Panda Zhuyin

Bopomofo without the misses.

Panda Zhuyin — Bopomofo without the misses.

A Bopomofo keyboard built for one-handed input. Panda Zhuyin packs 37 bopomofo symbols into a few large keys: tap for the center, flick four directions for the rest. Every key is "center + four directions" — wherever you tap or flick, you get one definite sound. Long-press a medial to open a selector, then flick once to pick the final — a full syllable in one motion.

Three clear zones: initials on the left, medials in the middle, finals on the right. Mandarin only uses 412 actual syllables, so impossible combinations are grayed out. Each key big enough you won't tap the wrong one.
