PentiKeyboard

well, I like the idea, and I started to learn it... but I'd prefer a physical keyboard or even an usual soft keyboard for long time usage because it's becoming harmful to use this kind of keyboard on a touch screen. You have to keep your fingers up in order to not touch anything, even if you can press out of buttons area to block the signal... it's not so comfortable. Also I have an issue... sometimes the 6th button is activating even if I don't touch anything.

Best keyboard alternative. Cool, beautiful, practical. Requires some time invest in learning but definitely worth it !

The best keyboard for Android by far. It takes time to learn but is really good especially for programmers and users of shells like Termux.

This keyboard is a cool futuristic type of keyboard. It took 45 minutes to learn the alphabet in my case. The repeat key is so handy for backspacing. It has a great variety of special characters and symbols. If there was a tab key, that would be nice.
