We’re very happy to ship our latest app for you:

Tips for Kindle – 133 Kindle Tips

It’s just $1 and here’s what you get for your $1 -

  1. 133 Kindle Tips. These are the best Kindle Tips I’ve found over the course of 3.5 years of blogging about the Kindle and searching through tips Kindle owners have shared. You will definitely find some real gems – regardless of your experience level with your Kindle.
  2. The Ability to add your own Kindle Tips. It’s a living breathing collection of Kindle Tips and you can add whatever great Kindle tips you find from other sources to have one handy reference.
  3. The Option to Select and Export Favorites. Choose your favorite Kindle Tips out of the ones included and the ones you add. Then view only those or export them in text format and read them on your computer or print them out.
  4. Slideshow Mode. You can watch a slideshow of the included tips, of your added tips, or of your favorites. There are three speeds and icons to indicate the speed and which section you are in.
  5. Usability enhancements – Two font sizes, lots of shortcuts, in-app help, downloadable help files at the Kindle Tips App Help Page. Open the Kindle Tips App and every time you get a different Featured Tip.

It’s basically a Kindle Tip & Tricks living list that you can carry on your Kindle and which will help you get the most out of your Kindle. The best Kindle Tips from us are included - and whatever you find yourself or on the Internet you can add in yourself.

What Kindle Tips is Not

  1. It’s not a Journal or a Notepad or a Flash Cards App.
  2. It’s not focused on free kindle books. Simply refer to the Free Kindle Books section of my blog if you want daily updates on offers and deals in the Kindle store.
  3. It only has 133 Kindle Tips that are stable and tested and secure. There’s nothing here that’s about hacking or removing DRM.
  4. It is not a User Guide. Please refer to the excellent Kindle User Guide.
  5. It is not a book. It only works on Kindles and not on Reading Apps.
  6. It is not a wireless email app or wireless syncing app. You cannot wirelessly sync with other Kindles. You can copy over the particular file that stores your tips (more on that later) but there is not wireless syncing.
  7. There’s no emailing because developers have to cover the cost of wireless usage and if we add email then it means that the price can’t be $1.

It’s also not free because it took a lot of effort to code all the features and find all the Kindle tips and we can’t sell it for less than it cost to make. We think $1 is a steal for 133 of the best Kindle Tips in an app that you can add your own tips to. Not to mention you get a slideshow mode which is very handy.

Where to get Help for Tips for Kindle

Please feel free to leave a comment here or email me at booksummit@ymail.com. For both suggestions and help these are the two best places.

Our Kindle App Blog has help including Downloable Kindle Tips App Help files in PDF and Word and Kindle format. It will get more help posts soon.

If you like the app please leave a review at Amazon and tell your friends. That would be a big help as a $1 price doesn’t leave much room for marketing costs.

Tips for Kindle – Credits

Andriy Kanyuka (Developer) – Tips for Kindle is a light, elegant app with some very useful features thanks mainly to Andriy’s coding skills. It’s really impressive to get a pretty app with 133 Kindle Tips, slideshow mode, and favorites in a light 150 kb package. Plus, everything is quick and intuitive.

Maurine Lee (Quality) – Maurine is responsible for the app being high quality and usable and out. She’s also done the excellent help documentation which you can download and read on your PC or Kindle.

Sergey Reva (Test) – Lots of testing and finding bugs so we don’t have to stumble through the app. Lots of useful suggestions too.

Digant Bhatt and Sergey Shevchenko (Design) – We really like the design and hope you like it too. And the icons and the fact that it’s still fast to load.

Jennifer Merkley – For suggesting the Slideshow Feature. It adds a lot to the app.

Amazon Kindle App Team and Andrea – For pushing us to make more than just a simple list of Tips. Which led to the feature of being able to add your own tips and select favorites and added motivation to implement Jennifer’s idea of a Slideshow Feature. Also for making sure all 133 tips were tested and safe and actually valuable (which is why ‘Use your Kindle as a Butter Knife’ didn’t make it in).

Official Kindle Forum and the Contributors – Excellent Tips and just a great spirit. People like Happy Reader Joyce and Emily Bronte and Bufo Calvin and Andrys and the ones contributing at the Discounted Books Thread and the Tips Thread help make the Kindle ecosystem better and happier. A ton of credit to all of them for finding and sharing such great Kindle tips.

Kindle Superstar Bloggers – Andrys at Kindle World and Bufo at I Love My Kindle. They keep writing about the Kindle and spreading Tips. Special thanks to Andrys as quite a few really good tips were first found via her blog.

Happy Reader Joyce – For her daily Free Kindle Books posts.

Me (Abhi) - Program Manager. I still don’t know what that really means. Perhaps just to make sure other people aren’t blocked by random things.

Google – For putting sites that steal this blog’s posts above this blog in the Search Rankings and forcing us to find other ways to reach and help Kindle owners.

Please let us know your suggestions and any tips you might find. The Tips would be especially appreciated. We’re looking forward to making the app better but no promises on when an update will come out.

Thanks to Nate the Great at The Digital Reader for mentioning the app already.

Kindle Notepad V1.1 – Kindle Notepad just got better

We are super happy to bring you Notepad V1.1. It has a lot of really good stuff. First, please take 5 minutes to read the details on how to do a backup and make sure you do a backup of your Notes. Then, read up on how to do the upgrade and go ahead and upgrade to Notepad V1.1.

Please Read – A Very Important Note on the Notepad Update

Firstly, PLEASE make a backup of your notes and your backups folder on your PC or Mac before doing the upgrade.

The upgrade works seamlessly and does not cause any problems. Plus we’ve tested it a lot on our end. However, it’s best to have a copy of your Notes in the rare chance something goes wrong. Please read this post for how to transfer files from Notepad to your PC – Kindle Notepad to PC file transfers. And then make sure you do a backup of your notes on your PC before doing the upgrade.

Secondly, if you have WiFi or 3G then do the wireless update. The wireless update works automatically and flawlessly.

If you have to do a manual transfer via your computer -> Please make sure it’s an overwrite. You should not move the existing Notepad.azw2 file (it might have a longer name) from your Kindle to your PC until the new Notepad.azw2 file is in the documents folder and working.

Note: If you are doing a manual transfer it’s 10 times more important to do a backup of your notes before doing the upgrade.

How the Upgrade is supposed to work

It’s a good idea to exit the Notepad app before starting the upgrade.

1) Go to the Notepad Product Page. There you will see:

At the right top of the page where the Buy button normally is:

Update Available

Version 1.1 (Released Mar 16, 2011)  (**The date is wrong – it should be today but it might show as Mar 16 instead of June 21)

Send wirelessly to:

[Your Kindle Names (dropdown)]    [Go Button (yellow button)]

-  OR – (this is text, it’s literally — OR —)

Transfer via computer (button)

2) In the dropdown with your Kindle’s name (or your various Kindles’ names) -  Choose the Kindle you have Notepad on. Then press the Go Button.

Note: If you have Notepad on multiple Kindles then you will have to repeat the entire process (not just this step) for each Kindle separately.

3) The new file downloads to your Kindle via WhisperNet and overwrites the existing file. This happens automatically.

Please Note: You should not delete anything yourself. This is very, very important. Please do not delete anything on your end – let the automatic overwrite happen automatically behind the scenes.

4) Run Notepad – You should see a Welcome Dialog. It looks like this:

The Welcome Dialog when you update Kindle Notepad to V1.1

Kindle Notepad V1.1

5) Read the Help Pages by pressing ‘Go To Help’ button in the Welcome Dialog (Or, in Notepad, press Menu and then choose Help in the Menu). Pages 5, 9, and 16 detail what’s added in Notepad V1.1.

6) Read the new welcome Note – It’s titled `Welcome Note.

7) If you like you can enter your contact information into the `If Found, Return To note. 

Just to be absolutely clear: You should not delete the Notepad file yourself (since that also deletes the associated data). It has to be a file overwrite and the update process does that for you. All you have to do is click the ‘Go’ button on the Amazon product page for Notepad.

If you do the download wirelessly then you can skip to the Notepad V1.1 Update (An Introduction) section lower down in the post.

What if you don’t have 3G or WiFi?

Then you have to be extra careful when doing the upgrade. In fact, if you can get access to 3G or WiFi it’s strongly recommended to do a wireless update.

1) Make sure you are not in the Notepad App. Plug your Kindle via USB into your Computer. It will show up as a disk drive (named something like Kindle (K:) or Kindle (D:)).

2) On the Notepad Product Page click the ‘Transfer via Computer’ button. This is right below the yellow Go button.

3) A ‘Select a Device’ dialog will show up. In the ‘Select a Device’ dialog choose the Kindle you have Notepad on. Then click the ‘Transfer via computer’ button in the ‘Select a Device’ dialog.

Please Note: If you have Notepad on multiple Kindles, you have to get a separate file for each Kindle.

4) You will get a file download dialog with options (options such as Open and Save). Choose Save.

5) This will give you a Save File dialog. In that dialog choose your Kindle (which you should have plugged in, in Step 1) and then choose the documents folder of your Kindle. Press Save.

6) You will get a dialog that asks you to confirm an overwrite of the existing Notepad File. Confirm the overwrite.

Please Note: In some cases you will simply see a Notepad.azw2 file as the new file, while the existing Notepad file will be named something like Notepad_ASIN_B004LSLN0I.azw2. In that case, just copy the new file to your Documents folder. Make sure not to delete the older file.

After the download of the new file is done – Unplug your Kindle and open the new Notepad. You might have to try both ‘Notepad’ files listed. The new one is the one which gives you a Welcome Dialog. Once you have opened up the new Notepad and gotten the Welcome Dialog (shown above) – Then you can plug the Kindle back via USB into your PC or Mac. Then you can move the older Notepad file (the one with ASIN etc. in its name) to a folder on your Kindle. Do not delete it from the Kindle itself (i.e. do not delete it when unplugged from your PC) - just move it to a folder on your PC when you have your Kindle plugged into USB.

Very Important: Please do not move the older Notepad azw2 file out of the Documents Folder (and off of the Kindle) until the newer one is in place. Please do a backup of your notes BEFORE doing the upgrade.

What if you don’t get a File Save Dialog?

If the new Notepad.azw2 file gets saved to a Downloads folder (without giving you the option to save it to your Kindle’s documents folder) – then please copy the downloaded file and paste it yourself into the Kindle’s documents folder. At no point should you delete anything on your Kindle. Do an overwrite of the existing file – that is the correct way to do it. If the older file has a different name – then move it only AFTER the newer file is added to your documents folder and you have confirmed that you get the welcome dialog.

What not to do: Do NOT Delete the existing Notepad file in documents folder. First move the downloaded Notepad.azw2 file to the documents folder and make sure it’s working – Then move the older file (if it hasn’t been overwritten) to some folder on your PC or Mac. Please do NOT plug and unplug the Kindle while file download or overwriting is happening.

***This is a very good reason why it’s best to first do a backup of your notes before doing the upgrade.

Correct thing to do: Backup your Notes on your PC or Mac. Plug in your Kindle to your PC or Mac. Copy new Notepad file you get from Amazon into Documents Folder of your Kindle. When it asks if you want to overwrite the existing file – Choose Yes. If overwrite doesn’t happen, check that the new file works and you get Welcome Dialog – Then move the older file to a folder on your PC or Mac.

If you have doubts or questions please email me at booksummit@ymail.com.

Anyways, that brings us to the actual Notepad V1.1 Update.

Notepad V1.1 Update (An Introduction)

Notepad V1.1 has the following improvements:

  1. Persistent Shift. To get capitals you can now press Shift, let go, type ‘a’, and get ‘A’.
  2. The largest font size is now bigger. Earlier it was 30 and now it’s 33. Note: Your current font size doesn’t change unless you go into Aa menu (by pressing Aa key) and change it.
  3. Anti-aliasing option on newer Kindles. On Kindle 3 and Kindle WiFi you can turn on anti-aliasing.
  4. Speed Improvements. With Notepad V1.0 once you crossed 100 notes you’d see slowness and would also see things slow down quite a bit once you got to 200+ notes. With Notepad V1.1 even 300-400 notes work relatively fast and everything is faster to use. More on speed improvements at the end of this post.
  5. Word wrap. Now words don’t get cut at the end of a line.
  6. Smart Note Save Notification. Now the note save notification doesn’t take focus and doesn’t stop you from continuing to type. Press Alt+S and the note save notification appears at the top and you can just continue typing.
  7. New Movement Shortcuts. Move around quicker using handy shortcuts:

    Shift+Next Page: Goes to the End of the Note
    Shift+Prev Page: Goes to the Beginning of the Note
    Shift+Right on the 5-way: Goes to the end of the Line
    Shift+Left on the 5-way: Goes to the beginning of the Line
    You can press Shift and Up to scroll up quickly.
    You can press Shift and Down to scroll down quickly.
    Next Page goes to Next Page of the Note (Page Size = amount of the note you see on the screen at one time).
    Prev Page goes to Previous Page of the Note.

  8. Quick Delete feature – Press down on DEL and hold it. After around a second it starts deleting 4-5 characters per second.
  9. Undo Feature – Press Alt+Z to undo your last few moves one by one. If you delete something by mistake or want to undo typing you can press Alt+Z to Undo.
  10. Copy-Paste (Please Read the Details – This may or may not be your ‘perfect’ version of Copy Delete). Yes, Notepad now has Copy and Paste and Delete. It is a specific, limited implementation of Copy-Paste – which may or may not meet your expectations. There’s an entire section on copy paste below.

Some Help documents for Notepad V1.1 (thanks to Maurine for writing these):

  1. Notepad V1.1 PDF –  Notepad V1.1 Changes (PDF).
  2. Notepad V1.1 Word – Notepad V1.1 Changes (Word).
  3. Kindle compatible (PDF will also work on Kindle) – Notepad V1.1 Improvements in Kindle format (mobi).  

Copy Paste in Notepad V1.1

Perhaps the coolest feature in Notepad V1.1 is Copy-Paste.

A few clarifications to set expectations:

  • We don’t have access to anything outside the app. Copy-Paste only works within the app.
  • There are no shortcuts. You have to use a tiny pop-up menu. Note: We had to keep things simple and we weren’t going to rework existing shortcuts. That’s why there’s no Ctrl+C and Ctrl+V.
  • Copy Paste works across notes within Notepad.
  • Copy Paste works in all fields.
  • Copy Paste is persistent. So if you exit app and re-enter – that copied text will still be there.
  • You can only copy one thing at a time.
  • This is the first version of the feature. There might be bugs and there might be some obvious way to make it better – let us know your suggestions.

How Copy-Paste works is very similar to how Highlighting works in Kindle Books.

To Copy Something:

Move the cursor to the beginning of the section you want to copy. Press down on the 5-way. The cursor will become slanted (italic). Now move the cursor up, down, left or right and select whatever text you like. Text will be highlighted based on where/how you move the cursor.

Once you have highlighted the text you want to copy - press on the 5-way again to get 4 options.

  1. Copy – This will copy the highlighted text.
  2. Paste – This will paste whatever text is currently in memory over the selected text.
  3. Delete – This will delete the highlighted text.
  4. Cancel – This will cancel the highlighting.

Please note that all the movement shortcuts work while you are in Copy-Paste mode. So you can press on the 5-way at the beginning of a line and then press Shift+Right on 5-way to highlight the entire line.

To Paste Something:

You must have something copied in memory.

Move the cursor to wherever you want to do the Paste. Click on the 5-way twice. You get the Copy-Paste Menu. Click on Paste to paste the copied text (whatever is the last text copied into memory) at that spot.

To Delete a Block of Text:

Go to the beginning of a block of text. Press on the 5-way to go into Copy-Paste mode. Move the cursor to select/highlight the portion of text you want to delete. Press on the 5-way again and from the Copy-Paste popup Menu choose ‘Delete’.

If you delete something by mistake – you can get it back by pressing Alt+Z for Undo.

What else is in Notepad V1.1?

Mostly fixes and tweaks.

There will be a Note created automatically called `If Found, Return To. This is a note where you can add your personal information. In case someone finds your Kindle and opens the Notepad app they might run into this Note and know how to contact you.

There are several fixes including:

  1. When you press Alt+S and then press Home: There is no longer an extra, redundant copy of the Note created. Note: If you don’t press Alt+S and press Home by mistake – the copy will still be saved.
  2. There was a bug where renaming a note from TestNote to Testnote (N to n) caused the Note to disappear. That’s now fixed.
  3. A few other bug fixes.

In addition to the six backup slots (which you can use to do in-app backups), there is now an Auto Save slot. This saves a backup every week – automatically. It’s important to backup yourself too and it’s especially important to backup your Notes to your PC or Mac. However, this Auto Save slot adds a bit of security.

A Quick Clarification: If you try to open an external imported Note (text file created outside Kindle Notepad app) that is larger than Notepad’s Largest Note Size then it is not deleted or lost. It is simply left untouched. Instead a copy is created and that is truncated to fit within the size limit. So, if you try to open TooBig.txt then Notepad makes a copy, truncates it to fit the limit, and opens that. The original TooBig.txt file is left pure and untouched and there is no data lost at all.

There is now a ‘More from 7 Dragons’ link in the Main Page Menu of Notepad which takes you to the Kindle Store and shows a list of our apps.

Speed Improvements

You should see faster performance everywhere -

  1. Faster page turns.
  2. Faster font changes.
  3. Faster search.
  4. Ability to handle 200 to 300 notes quickly and gracefully. We’ve tested up to 400 notes on Kindle DX 1 and Kindle 3. Beyond that you’ll probably see slowness in some things such as changing font type. We haven’t really tested it with anything above 400 or so notes
  5. You might notice faster typing too – it was pretty fast to begin with and we don’t know how to quantify the improvement.

It’s just much faster to use overall - do let us know if it still isn’t fast enough for you. If possible, we’ll look at further speed improvements in future updates.

Keep letting us know your suggestions

Every item on the Notepad V1.1 improvements list is a customer suggestion.

Let us know what else you would like to see in Notepad. There are some things that are not possible or interfere with the simplicity of the app and therefore will probably not make it. Copy-Paste was a borderline feature and things more complicated than it probably aren’t a good fit for Notepad.

Everything else (that affects and/or helps at least 5% of Notepad users) we’ll try to get in (at some unknown point of time in the future).

Some new low priced apps for your Kindle

A couple of app developers have gotten in touch and they have pretty interesting apps available -

  1.  Kee-Ko’s Quest by A Gamz is a fun puzzle game. It’s $1.99. A Gamz also made Maze A Thon which is a really good ‘get the mouse to the cheese’ puzzle game and is rated 4.5 stars on 47 reviews. That one is just $1. Kee-Ko’s quest is very easy to use as it lets you use the keyboard and 5-way to move things around. It’s sort of like Sokoban and Pirate’s Quest and is a good puzzle game. I like how they link up all the levels by giving it an end purpose.
  2. The unfortunately named Futoshiki by Braintonik Games seems to be a really good game at $1. The reviews are effusive and it seems fun. It’d be nice if app developers chose a name that was – pronouncable and memorable.
  3. Fortune Teller by Sonic Boom is a fortune app. You can choose fortune cookies (only 3 a day unfortunately), have Hector the mysterious and ring-obssessed tell your fortune, and you can get the mystic pyramid to advise you. Very good graphics and who doesn’t love fortune cookies.

It is interesting to see the types of apps being released. A Fortune Teller app in particular is a very good sign that Kindle App developers are experimenting in new areas.

Kindle Calculator App

Our Kindle Calculator App is now out. It’s $1.

You can find downloadable help files at the Kindle Calculator Help Page. The app itself has a comprehensive help section – Press Menu and then choose Help.

You can find a few videos at the Kindle Calculator Videos Page. Have to replace these with better ones but these do a decent job of showing the Calculator’s features and walking you through how to use the “%” function to calculate tips and discounts and totals.

Should you buy Calculator?

Well, the first thing to know is that the Kindle comes with a very basic Calculator built-in. You can just type 345*32 on the Home Page and press Enter. The first search result on the Search Results page will be the answer. So, if you can get by with this, then you don’t need Calculator.

Reasons for buying our Kindle Calculator App:

  1. It’s very simple to use. You can use a NumPad layout for typing numbers OR you can use the cursor OR you can use number keys (if you have a Kindle 2). You can press Space or Enter or the ‘=’ button to calculate a result. So, no worrying about SYM and Alt+QWERTY.

    Keyboard Shortcuts for Numbers are in a NumPad layout:
    7 8 9        Q W E
    4 5 6        A  S D
    1 2 3        Z  X C
    0               Shift

  2. It’s Fast. Calculator uses zero images so it’s small (just around 100 kb in size) and very fast.
  3. It’s Flexible. Since there are no fixed images there is a lot of customization possible – Choose from 3 font sizes, go with either of 2 themes (black or white), and either display keyboard shortcuts on the buttons or hide them.
  4. It’s Forgiving – We built it so it doesn’t punish mistakes. If you type in a wrong calculation or want to go back to a previous step – simply use the special Undo feature that walks you backwards through your calculations. Example: 23*25=575, then 575+200=775, and finally 775-155=620. If you want to go back and change what you added to 575, just press Undo button (U key) three times to get back ’575+’. Then you can add whatever you intended to add. You can also use DEL key to do digit by digit Undo.
  5. Tired of being able to save just one number in Memory? Our simple solution is to have a Calculator History page that displays the last 10 calculation results and the last 10 numbers saved in memory. It makes things a lot simpler. Calculator History page keeps these 20 numbers available for next time if you exit the app.
  6. It’s Friendly – The App itself has a Help section that explains each function and a Shortcuts List section that lists all the shortcuts. The downloadable documents at the Help Page listed above can be read on the Kindle (choose the Kindle format files) or on a PC or Mac (choose PDF or Word).
  7. Full Support – Leave a comment here or at our Kindle App blog (the two links above) or email us (App has the email listed on About Page). We’ve taken pains (such as writing Help documents and shooting videos) to explain how to use Calculator features and will be glad to answer any questions.

Kindle Calculator is well worth a shot.

Things Kindle Calculator is Not

  1. It’s not free. It took time to get all the little features like History and Keyboard shortcuts in, and to make it work with different fonts and themes.
  2. It’s not a scientific calculator – The only functions supported are +, -, *, /, x^y, 1/x, square root, %, sine, cosine, tangent, and memory functions.
  3. It’s not a graphing calculator.
  4. It’s not form over function. So there are no animated page turns or wooden shelves or photos of butterflies. We had a unicorn but it ran off with a zebra.
  5. It’s not infallible. It’s V1 and there might be some eccentricities and some obvious things you think a Calculator should have, that it doesn’t have. Let us know and if possible we’ll add them in a later release.

Credits for Kindle Calculator

Andriy Kanyuka - Developer & Idea of making it without Images. The speed and simplicity and ability to transform (themes, fonts, display shortcuts or not) is all because Andriy managed to make a Calculator that doesn’t use any images at all. We gave Andriy a PSD (Photoshop File) of what the Calculator should look like and he did the design without using the image – which you have to admit is pretty cool.

Maurine – Quality. Maurine made sure everything worked and worked better and was simpler. All the Help documentation and the in-app Help and Shortcuts List are also thanks to her. It’s great because it lets you get the most out of your Kindle Calculator.

Chetan Sachania & Sergey Shevchenko- Design.

Lorraine & Tony – Beta Testers. Thanks a ton to Lorraine and Tony who volunteered their time and gave us some excellent suggestions and found lots of bugs. You can thank them for us adding in a larger font size, removing a lot of extraneous things from the main view, and fixing a lot of bugs which would otherwise be swarming all over your Kindle (and maybe even all over your hands).

Amazon – Lots of Improvements including faster cursor speed, using the NumPad layout for numbers, and using intuitive keys like Enter and DEL intuitively.

Me – The idea of adding an Undo feature and a History Page and a white theme (in case you prefer vanilla ice cream). Guarding the wagons against the Vampire Apaches.

Thanks for reading through this. With Notepad and Converter and Calculator we are steadily adding the Kindle apps we think Kindle owners would find most useful - most of the big ones are still in the works so do stay tuned.

Finally, thanks a ton to the bloggers that have written about Kindle Calculator -

  1. Andrys at Kindle World.
  2. Steve at Kindle Nation Daily.
  3. Kindle App News.

Their help is greatly appreciated.
