Liminal Flow vs Somaphi

Liminal Flow has no write-up on Specifiction yet; its figures are above.

Somaphi is a generative audio app for meditation, sleep, calm, focus, and flow. Its native C++ engine creates sound on the device in real time rather than playing recordings or loops. Five modes—Sleep, Drift, Calm, Focus, and Flow—use their own frequency ranges, scales, reverb spaces, and ambient textures. Sessions include a breath guide with inhale settings of 3, 4, 5, 6, or 8 seconds. Users can improvise with a chromatic keyboard tuned to the active scale, choose among three sequencer patterns, or use Symphony mode for continuous phrase and chord decisions. The free plan includes five modes with no account or subscription. Studio Pro adds keys, scales, chord voicings, 432 Hz tuning, breathing patterns, recording, and audio export. It is listed at $12.99 a month, billed as a one-time purchase. Exports can be lossless WAV, AIFF, or M4A, and the maker says they require no license, royalties, or attribution for listed uses. The maker says the app works offline, does not track users, and renders audio locally. It is available on iOS; Mac compatibility requires macOS 12.0 or later and Apple M1 or later.
