About Thumb-Key APK
Thumb-Key is a privacy-conscious smart keyboard, made specifically for your thumbs. It features a 3×3 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 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) MessagEase Keyboard, which is its main inspiration.
Thumb-Key APK was developed by Dessalines and is available under the AGPL-3.0-only open-source license. This means the source code is public and anyone can inspect it. If you like System apps, you can also browse more apps in this category.
