Kinetica

Kinetica is a keyboard for two thumbs at once. Each thumb swipes or taps on its

own, at the same time as the other, and the two streams merge into one word.

Typing "something": the left thumb taps S, then E, while the right thumb swipes

O -> M and then T -> H -> I -> N -> G. Kinetica merges them into S + OM + E +

THING.

It is a spiritual successor to the discontinued Nintype, written from scratch on

Android's public IME APIs: not a fork, and no third-party gesture or prediction

library. The dynamic time warping, the trie search and the two-thumb merge are

all in the app.

The app declares no INTERNET permission, so nothing you type can leave the

phone. Decoding, prediction and learning run on the device, and password or

private fields turn off suggestions, trails and learning.

Features

* Two thumbs, each read with its own cursor, so a word can pass between them in

any order; one tap can stand for a double letter

* English, Italian, Spanish, Polish, Czech, Dutch, German, French and Norwegian,

plus Russian, Ukrainian, Hebrew and Arabic as experimental: 46k to 50k words

per language with real corpus frequencies. Accented words are drawn on their

base keys and restored on commit

* Several languages at once: mix two in the suggestions, or let the keyboard

follow the language you are typing

* Next-word suggestions, recent words on the bar, and a correction strip right

after each word

* Tap inside a word you wrote to swap it for another; swipe shift to change

its case
