Description
Thumb-Key is a privacy-conscious smart keyboard, made specifically for your thumbs.
It features a 3x3 grid layout, and uses swipes for the less common letters. Its easy to learn, and designed for fast typing speeds.
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 approximate 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) Message Ease Keyboard, which is its main inspiration.

I've used Messages for 16+ years now. But now that it's gone to a subscription model, I abandoned it completely. I tried a variety of other keyboards... but nothing could compare. After googling for a while, I found thumb-key. It has the same key configuration, but the letter, are arranged differently. I was so pleased to see that I could arrange the keys to be the same as message ease, in the settings. So... I didn't need to have a learning curve. There are minor differences, most good

Deleted Messages, came here instead. I would like to see: 1. Adding '+' to the end of a string and hitting 'backspace' capitalizes the first letter: eg 'george+' & 'backspace' becomes 'George'. 2. adding '-' to the end of a string and hitting 'backspace' deletes the whole string: eg 'George' & 'backspace' = ''. 3. 'Underscore' is optionally used instead of the space bar (or set select your own symbol); 'return' is then a swipe down from 's'; more space, less keyboard.
