We make sound apps for Android: precise, easy to use and respectful of your privacy. The sound is generated on your phone, with no accounts, no ads and no internet access.
Meditation in sound tuned to your own voice
Resonance Meditation
Hum a comfortable tone for twelve seconds and the app recognizes your note, then tunes the whole session to it: the base tone, its harmonies, the binaural layer and the breathing rhythm. Eight ready Sequences, a Custom session builder, a breathing guide and practice with the phone locked. Tuned to A = 432 Hz.
A precise frequency and sound generator
Tone Generator
Tones from 20 to 20,000 Hz with 0.01 Hz accuracy, four waveforms, sweeps, white, pink and brown noise, and notes and cents with A4 at 432 or 440 Hz. For testing speakers and headphones, tuning and acoustics experiments. The Plus edition adds beats, a speaker phase test, layers and overtones, a live spectrum and export to WAV.
What our apps have in common
- Privacy. No accounts, no ads and no analytics. The apps have no internet access and analyze your voice only in your phone’s memory.
- A fair model. The core features are free, and the Plus edition is a one-time purchase with no subscription.
