Simple Apps That Just Work
We build simple applications. Anyone can build complex — simplifying without losing functionality is much harder. We're tired of cluttered interfaces with hundreds of settings. Simplicity is when everything works without unnecessary questions.
A singing-bowl drone synthesizer you play by drawing. Trace a shape to start a sustained drone, stack several into a living chord, and drag to morph shimmer and timbre. No presets, no knob walls — just your finger. Works fully offline
Download on App StoreA theremin you play in the air. The front camera tracks your hands — raise them for pitch, pinch for volume. Continuous, no touch, polyphonic up to four hands. Fully offline: no mic, no network, no accounts
Download on App StoreA pocket touch synthesizer — a stylophone you play with your finger instead of a stylus. Slide across a hex keyboard and shape one electronic voice live with a handful of knobs. Four waveforms, fully offline
Download on App StoreA microtonal MIDI keyboard for quarter tones. The scrollable hex layout grows out of the familiar piano — flip from 12-TET to 24-TET and watch the quarter tones sprout between the notes. Play by touch or glissando and send MIDI straight to your DAW, synth, or hardware. Built-in voices let you hear yourself as you play
Download on App StoreA doomsday shortwave buzzer emulator. Recreates the eerie atmosphere of the real Russian numbers station on 4625 kHz: a continuous carrier buzz over a bed of shortwave static, interrupted now and then by a robotic voice reading a coded message — all behind a live waterfall spectrogram. Built for atmosphere, not utility. Works offline
Download on App StorePoint your phone at any music and it names the key, scale, and mode you're hearing — then lights those notes up on guitar, bass, and piano. The missing bridge between key finders that only listen and scale charts you have to read yourself. On-device, mic only, no cloud
Download on App StoreLive sound drawn as it happens.
