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.

This keyboard has MANY great features, which make it very desirable, however it is so buggy that it makes typing messages ten times longer than necessary. The cursor shoots all over the place; words in random places get changed when typing. Its a mess. I really want this to work. One feature that would make a huge difference would be an undo button, so i can undo the mess this keyboard makes.

I bought a phone that has a common fault - it won't recognise touches on the very edges of the screen properly. The built-in keyboard worked fine...if you never use the spacebar, the backspace key or the letter p. It literally took the P. I downloaded this app and set it all up in about two mins. Problem solved! All keystrokes now register. Every lovely letter works once more. Many thanks! It was driving me insane.

I tried the app, and liked it immediately, except for the ads which took up space. I then purchased the app, and worked well in getting rid of the ads. Much easier to use with out them. But one big problem...I am unable to use the emoji icons in sms text. Instead of the picture, a small black triangle with a white question mark inside is shown instead. I have tried all different ways to get it to work, but to no avail. Settings are no help, and help button gives contact information, but unable to send an email,(on website, it is in Russian language). I would like to know how to fix this, then I will give it 5 stars, when I can use the emojis.
