KT9
The 9-key T9 keyboard, fast and private.
KT9 brings classic 9-key T9 typing to Android — fast, accurate and 100% offline. With big, readable keys, it's built also for anyone who struggles to hit the tiny keys of ordinary keyboards. Type one-handed on the T9 keypad, or switch to a full QWERTY (QWERTZ and AZERTY too): one smart engine powers both. Everything stays on your device: no account, no trackers, no ads, your data never leaves the phone.

Key features
Easy to read and easy to hit
Senior mode: bigger keys and text, taller keyboard, strong vibration. Key preview bubble, adjustable long-press and a simplified look. Works with any theme.
Prediction measured, not promised
Quality verified with a repeatable benchmark on real texts: in Italian, 96% of words come up as the first suggestion and 100% within the first three. The engine learns what you actually use — while staying private.
T9 and full keyboard
Predictive 9-key T9, ABC multitap and a 123 keypad, plus a full QWERTY / QWERTZ / AZERTY. Three keypad layouts (Modern, Classic, Xperia). Adapts to the field (phone → 123, email → letters).
Nine languages, offline
Italian and English built in; download Spanish, French, German, Portuguese, Dutch, Polish and Romanian. Multilingual suggestions and automatic language detection (optional).
Built for one hand
One-handed mode, adjustable height, gestures (swipe to delete a word, long-press for numbers and accents) and instant undo of the last correction. Gestures can be turned off.
Your dictionary, your rules
Add your own words, favorites, abbreviations (shortcuts that expand as you type) and a block list. Back up and restore as a local JSON file. Full Privacy mode disables all learning.
Clean, fast, light
Compact memory-mapped dictionary: instant startup and snappy suggestions even after years of use.
