How does this work?
Clicking the “Test drive now” button launches a copy of this app on Amazon Elastic Compute Cloud (EC2), a web service that provides on-demand compute capacity in the cloud for developers. When you interact with the simulated phone using your mouse and keyboard, we send those inputs over the Internet to the app running on Amazon EC2 — just like your mobile device would send a finger tap to the app. Our servers then send the video and audio output from the app back to your computer. All this happens in real time, allowing you to explore the features of the app as if it were running on your mobile device.

Product Description

End the thumb wars with Thumb Keyboard

Thumb Keyboard introduces a revolutionary and innovative split layout keyboard for tablets and phones that makes thumb-typing easier and more comfortable. It also acts as a standard keyboard with numerous customizable features.

"An epic win for tablet typing." - Android Police

"Thumb Keyboard on Android phones takes customization to the next level." - Laptop Magazine

Rule of Thumbs

Thumb Keyboard offers a welcome solution to the uncomfortable stretching and juggling that often accompany thumb typing. This app has a keyboard layout to fit your needs, whether you're typing on your phone or tablet.

The split tablet keyboard brings thumb-typing ease

Choose from seven different keyboard layouts with special accommodations for comfortable thumb-typing. Several layouts are designed specifically for Android phones, each ergonomically designed for fast and comfortable input. Innovative split layouts feature wider keys, better layout for thumb-typing in portrait mode, and increased accessibility to keys when typing in landscape mode. Split layouts for tablets and large-screen devices feature increased accessibility to keys for thumb-typing on 5-inch, 7.1-inch, 8.9-inch, and 10.1-inch tablets.

These layouts offer predefined combinations. You can also choose your own layout combination for portrait or landscape view.

Features: Thumbs Up

Thumb Keyboard offers a whole heap of customizable features. Select your theme, background, keyboard height and width, secondary symbols, key size, font size, and keypress sound. You can also minimize or hide the keyboard; hide the right shift key; mark the two key blocks on the split keyboards with different colors; and access QWERTY, QWERTZ, and AZERTY keyboard layouts.

Set your theme, background, and much more

Other features include auto-correction, voice input (Android 2.2+, English only supported), a user dictionary, separate number keys and cursor keys in most layouts, fast switching between layouts, adjustable height (with separate adjustment of bottom bar), and easy popup keyboards (for additional characters, numbers, and smileys). Thumb Keyboard supports text prediction for numerous languages including English, Spanish, German, French, Italian, and Dutch.

Thumb Keyboard also uses Bigam Prediction, an algorithm that helps you type faster by predicting what you want to say. The system looks at what you have already typed and how it is used in the context of the sentence, and then provides a best guess of what you'd like to say next. With this method, there's no waiting around for your app to learn how you type. This feature will only work on Android 2.3 and Honeycomb.

Multilingual Typing is a Breeze

Thumb Keyboard supports a wide range of languages including English, Russian, German, modern Spanish, Norwegian, Swedish, Danish, and Finnish. The app automatically selects the keyboard corresponding to your system default language. If you have selected more than one language within the Thumb Keyboard settings, you can easily switch to the secondary keyboards at any time by sliding your finger across the spacebar.

Button Up, Down, all Around

You can also create your own custom buttons. When pressed, these buttons perform numerous small commands or can even be used to store commonly used words or phrases. To create buttons, simply tap the icon and type any word or phrase into the text field. It could be as simple as "lol" or as lengthy as "I'm on my way but caught in traffic." There is also a dedicated row of buttons that can be similarly programmed. Typing on your phone or tablet doesn't have to be a war when you have the Thumb Keyboard app.

Thumb Keyboard is compatible with Android 2.2, Android 2.3 (Gingerbread), and Android 3.0 (Honeycomb). Viewsonic G Tablet users must follow a special installation procedure for third-party keyboards.

Sometimes we are lucky with an app we download for our Android because it shouts 'professional design' and 'quality'. And Thumb Keyboard is one of them. It's a highly customizable, well designed, predictive THUMB, ONE-HAND and FULL keyboard app (yes, you get all three).


The developers not only provide on in-app setup screen that explains in detail and how to install this on Android 2.x and Honeycomb (separate sets of instructions) but there is also an embedded link to a Web side that has even more detail. As I proceeded with the setup, additional tips/warnings popped up, usually at the exact time I needed them.


Rather than gush about what you get with this app, let me calmly enumerate the options and let everyone decide:

- Separate keyboard sets for whatever kind of device you may have: phone, 7" tablet, 10" tablet.
- 28 themes, all free, some may require a download.
- SIX separate keyboard layouts: thumbs, right-hand only or full keyboard, each with or without customizable function keys.
- Sound - six custom sounds, from 'dvice default to typewriter to water drop.
- Sound volume
- Vibrate (or not) on keypress and vibration's strength
- Key popup feedback on/off
- Background if you want something other than the themes provide
- Adjust keyboard's dimensions - height (portrait or landscape mode), width... too many options to enumerate here
- Custom symbols

And there's more. This is a predictive keyboard where the most likely words are displayed as you type letters. Even better, and this is the difference between intelligent design and something done in a hurry, little details are addressed.

5.0 out of 5 stars great keyboard. July 27, 2011
It's a great keyboard and the hybrid split layout for portrait view works great on larger (4") screens. In my experience, it hasn't been any faster or slower than my other favorite keyboard, smart keyboard pro.

To the reactionary "unsafe app?" reviewer: the disclaimer about capturing the text is displayed by android because, well, it's an input app. Of course the things you type in it could be stolen if the app was malicious and intended on doing so. This is not the case with this app or any other reputable input app here or on the google market. Try any add-on keyboard and you'll see this is the case. Too bad you left a bad review of a developer's hard work because you're too dumb to research it yourself.

5.0 out of 5 stars best keyboard for Android tablets so far June 16, 2011
Verified Purchase
I used to think my 7" Android tablet was small enough to use with a standard configuration Android keyboard. When Amazon dropped the price on the Thumb Keyboard to 99 cents, I figured I'd give it a try. This is really great. In landscape mode, it displays all the alphabet keys and number keys at the same time so I no longer have to switch between modes. Even in portrait mode, the text prediction is much better than any other keyboard that I've tried. Thumb Keyboard doesn't have a "swype" mode, but that never works well with word predictions and swyping on a tablet-sized screen is kind of cumbersome anyway. Thumb Keyboard has lots of customization modes (like alternative layouts) that I may look into, but the basic layouts for each device size are probably best for most people.

1.0 out of 5 stars Great keyboard, but amazon ruins it July 29, 2012
By James
Verified Purchase
This is by far the best keyboard I've ever used, but amazon ruins it by not having more timely updates, they need to let the developer have control when it comes to updates especially for a keyboard app, they are currently on version 4.5 with this app while we are still stuck on (amazon app store), practically 2 whole versions, and i would have never known this had i not been browsing the google play store, this is where i think amazon is short ending us as customers by not updating our apps. There are important bug fixes and extra features we're missing out on due to amazon!

3.0 out of 5 stars No dvorak layout October 3, 2011
Verified Purchase
As a thumb keyboard this application works well. Plenty of thought has gone into the key position and size. With several language choices and layout variants. Its strange that a Dvorak variant is missing for English when are Azerty and Qwertz are present. As an Android user I want to use this keyboard. As a Dvorak typist I cannot.

5.0 out of 5 stars Best Keyboard Ever. Must Have for Tablets June 15, 2011
Verified Purchase
This keyboard is perfect for tablets and I refuse to use anything else after 2 mins of use. I have a Nook Color which is a 7" tablet. This keyboard has a ton of option for from phone layouts, two 7" tablet layouts, and bigger tablet layouts. It also lets you set a portrait and a landscape layout of your preference. The major beauty of this keyboard is that you don't have to struggle anymore which keys in the center of the keyboard anymore no matter how big your device is in landscape or portrait. It split you keyboard in half making a letter keys reachable on either side of your screen. The keyboard also looks quite elegant. You can choose all type of skins from honeycomb, ipad, windows7, gingerbread etc. Your guaranteed to find something you like. Another feauture I like is the ability to adjust height of keyboard so you can make it how tall or short you want. The keyboard itself is quite smart also. It has good text prediction and the fastest easiest way of using numbers I've seen on a keyboard.

Bottomline: Must have if you have or ever plan on having a tablet. Also a must have if you have a large screen phone such Evo, Thunderbolt, or Dell Streak. Just a really great keyboard no matter how you look at it. Its a steal @ 2.50 but even more so on sale @ a measely 99c
