Jayan

Jayan is a generative lo-fi radio station that plays in real time on your device. Choose a scene, press Play, and settle into warm chords, relaxed rhythms, and ambient textures. Six stations offer different musical moods: late-night jazz, tape study, rainy keys, dusty beats, bossa, and ambient night. Recurring melodic themes develop through calls, responses, changing harmonies, and intentional space. A calm illustrated player keeps listening simple. Pause and resume the same session, save a favorite sound to return to later, or set a sleep timer. Auto DJ can guide the music through new scenes while preserving your listening volume. Open the Sound Studio to adjust mood, warmth, swing, melodic space, rain, instrument colors, and the mix. Share a recipe to restore the same generated session on another device. Background playback and lock-screen controls keep your music close when the app is out of view. Highlights - Six distinct illustrated stations with locally generated music - Developing melodies, varied bass and drum phrases, and balanced output - Local saved sessions and a cancelable sleep timer - Reliable pause/resume, background audio, and lock-screen controls - Sound Studio, recipe sharing, and playback diagnostics - Native iPhone and iPad layouts with English and Simplified Chinese support No account or fixed streaming playlist is required.

Verdict
The clearest difference is in-app purchases: Jayan at none against Synth Box's 3. Synth Box's advantage is iOS requirement (15.0 vs 17.0). On price, update cadence, ads and device support there is nothing between them.
