FXboard

FUTO Keyboard is a good modern keyboard that stays offline and does not spy on you. FXboard is an unofficial fork of it that adds keyfx effects and a few typing extras, for phones without root. It keeps everything FUTO Keyboard does (offline, private, swipe typing, voice input, predictions that learn on your phone) and tracks FUTO’s upstream code.

What it adds. Every keyfx effect, live on the keyboard, with key pops that scale the real keys and letter hop that uses FUTO’s exact swiped word. A vertical spacebar cursor that moves between lines when you drag up or down. An option to hide the keyboard navigation bar on Android 15 and newer. A Keyboard effects page with a Preview button on each effect and an Import box for settings designed in the keyfx lab.

Safe to install. It installs as its own app beside the official FUTO Keyboard, so you can try it without removing anything. Every release is built by GitHub Actions from the commit it names and signed with the same key, so updates install in place and keep your dictionary and settings. It is free, with no ads and no paid features.

FXboard is not made, endorsed or supported by FUTO.
