About this app

I am 58 and my vision is far from perfect. I have fingers on my hands - not matchsticks, so I designed this keyboard for myself. If you’re under 35 and have no problems with vision, please do not install. You will need it later. But maybe it will be a good lifehack for your parents now.


This ergonomic keyboard for Android allows using 100% of your phone’s screen for big keys making it indispensable on small screen devices and for fat fingers (100% is not an advertising slogan: it is literally 100%). Swipe up to switch into 100% display mode.
This big keyboard preserves your vision and reduces eye strain.
Big keyboard keys are easier to hit – less typos.
The layout of this large keyboard for Android is easy to learn – it’s a QWERTY keyboard smartly compressed into extra large keyboard, what makes it ideal for large hands.

Ratings and reviews

Very useful app, highly configurable to suit individuals need. However when switched to Chinese text, the text bar turns black or sometimes white cannot see the text to select. Hope can improve and it will be perfect.

It tries to change what you are typing, its so annoying when you are on quora trying to help someone and then while you are texting someone or typing the text box disappears and or your words change into something you didnt say! And while you are typing Advertisments pop up. 😡. Its a good keyboard for big fingers but when you are typing and the letters seem to list different on screen. And the ads dont help either. Someone is behind the curtains pushing buttons. Hmm is this a hacking tool?.

Excelent! But why is the prediction font so big? Also the prediction area would work better if it could be constantly expanded to 2-3 rows. Also needs input language / dictionary switching hotkey and hotkey for cursor control window. I also want to use QWERTY for Čeština but it's QWERTZ only.
