An adaptive audio layer, not just background sound. Off by default.
soundscape
Hearing nothing on iPhone? Check the physical mute switch on the side — iOS Safari silences web audio whenever it's flipped to silent, the same as it would a video.

mode
"Café" isn't offered as a soundscape here — every sound in this app is synthesized live (no audio files), and overlapping café chatter doesn't synthesize convincingly. Everything else above is a real, live-generated sound, not a placeholder.
🪕
Kalimba
Play a short melody any time. After a 500 metre walk, you can also record it and leave it here as a Calm Echo for others to find.
Tap Record, then play something on the kalimba.
