FlickBoard
APK
FlickBoard is a keyboard for Android that doesn’t try to correct or predict you. It doesn’t have an opinion on the correct spelling or tone. It certainly doesn’t use any AI. Because it trusts you to write what you meant to write. Instead, FlickBoard uses swipes to get away with using vastly fewer (and larger!) buttons than a traditional QWERTY keyboard, helping you build muscle memory, minimize typos, and touch type faster. Type the letters in the center of a key by tapping it. Type the keys in the corners by swiping in that direction. It’s that simple! FlickBoard is inspired by MessagEase and Thumb-Key.

Florid is basically F-Droid client, but better looking? This project started out as a hobby or you can say an experiment. This app should be able browse, download & update apps from F-Droid. You might have a question, isn't there other client that does the job? Yes, but this is my take on the application from a UX designers perspective. This project would be UX first priority for me, so don't mind leaving your feedbacks on Github. This project might expand to allowing other repos like IzzyOnDroid.
