Description
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.
Recent changes: Improved custom keys in landscape mode.

Must have keyboard. I used 42 types of keyboards inside play store but no one get perfect typing they were perfect in designs and themes but purposefully not worthy. This app gave me a wonderful experience and typing feel. There is no mistake typing this qwerty pad. The auto prediction and letter highlight was superb. Only sticker or GIF were missing inside the app. I think future update will resolve this. The word highlighting is my favorite in this app. Dear developer thanks a lot... 😍

Big keyboard with nice styles, but the letters are not on the right places where they have to be, which is totally confusing and annoying as I always have to search the letters independent of the thing that it's impossible to see what I'm writing as the keyboard is that big even after changing the size. If you made a positive update I'd appreciate that much, and I'll install your keyboard again.

I really like 1C Keyboard because the large keys make typing so much easier, especially for people like me who struggle with smaller keyboards. However, the voice typing/mic option is hidden inside the emoji menu, which makes it slower and harder to access. Please add the mic button to the main keyboard screen, so it’s easy to use without extra taps. If this is fixed, I’ll gladly give a higher rating.
