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.

The ideal keyboard for use on a small screen with the ability to vary its size to suit your needs. Ability to customise almost every aspect of its appearance is really good. Spell check & suggestions are much better than main stream keyboards. As an older person whose eyesight & finer finger control isn't as good as it used to be this is really good with the larger keys. It took me a couple of days to get comfortable with the layout but it works great, fast & accurate. Pro is worth buying.
