MessagEase is an alternative, non-QWERTY keyboard for your iPhone and iPad. Created based on years of scientific research in user interface, MessagEase is designed and optimized for use on a touchscreen device. MessagEase is a patented, innovative design different from the antiquated QWERTY keyboard. If you believe that every keyboard must be QWERTY-like, then MessagEase is not what you are looking for. But if you are open to new ideas and up for experiencing a completely new way of writing you will be pleasantly surprised at how well, how precisely, and how fast you can enter text with MessagEase. Our current champion’s speed is 87 WPM— that's 87 Words Per Minute! Most people don't type nearly that fast with ten fingers! MessagEase essentially has 9 large keys with an optimized letter assignment to maximize your speed, increase your accuracy, and ease your writing. Since MessagEase is very different, you must spend a few minutes to get used to it. We have included several learning games to help you learn the new, innovative pattern of MessagEase—and you’ll save hours by texting and writing faster. With MessagEase you enter letters and characters with either a tap, or a drag (slide): taps for the most common characters and directional drag for the rest. Please watch the video, or see the section Essential MessagEase, to learn more. MessagEase's design is based on sound user-interface principles such as the Fitts' Law; it uses letter frequency and di-gram data to optimally place the characters on a keyboard with fewer, larger keys. That’s why the letter positions are non-QWERTY! If you are interested to learn more about the scientific details behind the design of MessagEase, please see this paper: http://www.exideas.com/ME/ICMI2003Paper.pdf We have lots of videos to help you become familiar with MessagEase quickly. Watch: http://www.youtube.com/watch?v=k3D3f3GWTSg There are many more on our YouTube channel. http://www.youtube.com/user/messagease Please also note that you can change the keyboard size by dragging up or down on the Globe Button. You can also reshape and recolor the keyboard in various ways. See Settings for details.

MergeKey — the first keyboard that hides the keys you don't need. As you type, MergeKey dynamically removes impossible letters and expands the remaining keys, giving you bigger tap targets and fewer typos. It's like autocomplete, but visual — you see your options shrink in real time. MERGE MODE — UNIQUE TO MERGEKEY - Keys that can't continue your word disappear instantly - Remaining keys grow to fill the space — bigger keys, fewer mistakes - Learns new words you teach it - Toggle Merge Mode off if you prefer just the disappearing keys without resizing 20 LANGUAGES English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Greek, Turkish, Russian, Ukrainian, Indonesian, Vietnamese, Swedish, Finnish, Danish, Norwegian, Romanian and Hungarian — each with native prediction and accented character variants. English (US/GB) and Portuguese (BR/PT) with correct regional dictionaries. SMART FEATURES - Prediction bar with word suggestions - Long-press for accented letters and symbols - Character preview bubble on key tap - Optional dedicated number row - Double-tap shift for caps lock - Backspace hold-to-accelerate (characters, then words) CUSTOMIZABLE STYLE - 4 keyboard styles: iOS 26 Liquid Glass, Classic, Flat, Flat Glass - Custom key fill and border colors - Transparency slider for key fill opacity - Spacebar icon options - Animation speed control BUILT FOR LEARNERS - Swipe up to teach MergeKey a new word - Swipe down for continuous mode (all keys visible) - Swipe left to delete whole words - Swipe right to repeat the last word - Built-in typing game to practice in any language PRIVACY FIRST MergeKey does not collect or transmit your typing data. Everything stays on your device. MergeKey never connects to the internet. The only network activity is the App Store handling the optional tips – that's why iOS shows a Mobile Data switch for MergeKey.
