Estua

Every meditation app loops the same 10-minute track. Estua generates music offline, locally — provably non-repeating audio for Focus, Relax, Sleep, and Recover, each with its own certificate proving it never plays the same thing twice. No streaming, no account, fully offline: the sound is synthesized in real time by a C++ engine, not pulled from a file. Pick a mode, and the music adapts and evolves for as long as you listen, multiple generative styles, a sleep timer, and a gentle sunrise wake.
