Somaphi vs Still

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.

Still is an iOS meditation app that generates tracks from user descriptions using AI. Seven presets are available: Ambient, Nature, Piano, Tibetan, Binaural, Lo-fi, and Classical; users can also describe a custom style. Sessions include 3-, 10-, and 30-minute examples, custom timers, and lengths up to 45 minutes on the listed plans. Generated tracks are saved in a personal library, while streaks, total minutes, session history, and the last session are tracked. The app works offline and supports Apple sign-in or guest use. It requires iOS 16 or later. There is no free plan, but a 3-day trial is listed. The monthly subscription costs $7.99 per month and the annual subscription costs $69.99 per year. Both plans allow up to two new tracks per day and auto-renew unless canceled at least 24 hours before the period ends. Payments use Apple In-App Purchase. Users retain ownership of generated content, although AI results are not guaranteed to be unique, high-quality, or suitable.
