Traditional T9

TT9 is a Nokia-style 12-key T9 keyboard. It provides predictive text input in 40+ languages, configurable hotkeys, clipboard, undo/redo, and extensive customization. It works on touchscreens, physical keypads, and TV remote controls. And best of all, it doesn't spy on you!

Supported languages: Arabic, Bulgarian, Catalan, Simplified Chinese (Pinyin), Croatian, Czech, Danish, Dutch, English, Estonian, Farsi, Finnish, French, German, Greek, Gujarati (phonetic), Hebrew, Hindi (phonetic), Hinglish, Hungarian, Indonesian, Irish, Italian, Japanese (Romaji), Kiswahili, Korean, Latvian, Lithuanian, Norwegian, Polish, Portuguese (European and Brazilian), Romanian, Russian, Serbian (Cyrillic), Slovak, Slovenian, Spanish, Swedish, Moroccan Tamazight (Latin and Tifinagh), Thai, Toki Pona, Turkish, Ukrainian, Vietnamese, Yiddish.

Philosophy:

  • No spying, tracking, telemetry, reports, or data collection of any sort.
  • No ads or unnecessary bells and whistles. It only does its job, typing.
  • No unnecessary network connections. The Full version operates entirely offline, and the Lite version connects only to download dictionaries from GitHub. Voice Input may require Internet access, depending on the available voice services.
  • Open-source, permitting you to verify all the above yourself.
  • Created with help from the entire community.
  • Things it will (probably) never have: QWERTY layout, swipe-typing, GIFs, and stickers.
  • Not intended as a clone of TouchPal, Sony Ericsson, KaiOS, Samsung, etc. While it captures the feel of the classics, TT9 offers its own experience and won’t replicate any device or app exactly.

Note: the Google Play version is almost identical to the lite version, except that it includes extra "premium" features that are closed-source. Nevertheless, none of the extra components compromises the principles outlined above.

System Requirements

  • Full version: Android 7.0 or higher
  • Lite version: Android 8.0 or higher
  • Storage space depends on the Android version. The lite version requires at least 6-8 Mb and the full version requires at least 220 Mb.
  • Extra storage space is necessary for language dictionaries in Predictive Mode.
    • Languages with character predictions only (Korean): ~1 Mb per language
    • Tiny languages (< 100k words; Kiswahili, Indonesian, Vietnamese): 5-6 Mb per language.
    • Small languages (100k-400k words; e.g. English, Norwegian, Swedish, Finnish, French): 15-30 Mb per language.
    • Medium languages (400k-800k words; e.g. Chinese, Danish, Greek, Italian, Portuguese): 40-75 Mb per language
    • Large languages (800k-1.6M words; e.g. Arabic, Bulgarian, Hebrew, Japanese, Romanian, Spanish): 100-170 Mb per language

Storage usage for the dictionaries depends on the word root count and the average word length in each language. Some languages will require more space, even if they have fewer words than others.

Compatibility

How to Use Traditional T9?

Before using Traditional T9 for the first time you need to configure it and load a dictionary. After that, you can start typing right away in one of the three modes: Predictive, ABC, or Numeric (123). And even if you have mastered the keypad back in the day, you will still find the Predictive mode now offers more powerful and smart new ways of typing with even fewer key presses.

So make sure to read the initial setup and the hotkey tips in the user manual. Also, don't miss the convenient compatibility options aimed to improve the experience in some applications.

The user manual is also available in: Brazilian Portuguese, German, French, Italian, Russian, Spanish, Turkish, Ukrainian.

Support

The best way to support the project is to give it five stars on Google Play. While it may sound trivial, good reviews really motivate me to keep working on it. They also encourage the Play Store to promote TT9 to more people and ultimately help spread the word.

You can also give the project a star on GitHub. Higher-ranked projects can access development tools for free and apply for funding more easily.

And if you truly enjoy using TT9, buy me a beer on Ko-Fi or buy Premium on Google Play.
