Thumb-Key is a privacy-conscious smart keyboard, made specifically for your thumbs.
It features a 3x3 grid layout , as many older phones had, and uses swipes for the less common letters. Initial testing shows that you can reach ~25 words per minute after a day of use.
Instead of relying on profit-driven, privacy-offending word and sentence prediction for accuracy, as do most popular phone keyboards like Gboard and Swiftkey, Thumb-Key uses large keys with predictable positions , to prevent your eyes from hunting and pecking for letters.
As the key positions get ingrained into your muscle memory, eventually you'll be able to appromixate the fast speeds of touch-typing , your eyes never having to leave the text edit area.
This project is a follow-up to the now unmaintained (and closed-source) MessageEase Keyboard , which is its main inspiration.
