I’ve looked at a few on fdroid and they all seem like they aren’t being maintained anymore.
Edit: I’ve spent the past day trying most all of the suggested keyboards here and I think I’ve landed on either Unexpected Keyboard or AnySoftKeyboard. Thanks for all the suggestions. Thumbkey is quite the thing to get used to.
Hey, thumb-key is really cool! I’ve been using it for a bit and it has solved my issue of constantly fat-fingering wrong letters into what I’m trying to type on other keyboards. I just want to say thanks for developing it and keep up the good work!
