Description by Yoji Hirabayashi Written by the developer, not by AppBrain. Click to read.
Sōon plays nine ambient and colored noises. Pick three favorites, put them in order, set a timer if you like, and listen. No accounts, no subscriptions, no endless catalog — just the sounds you actually use.
When you're ready to step away for a minute or two, Pause gives you three fixed patterns from the home screen — one to five minutes, with visual timing and gentle phase cues. If your sounds are playing, they pause while the session runs and pick back up when you're done. You can use Pauses on your own too, with no audio at all.
Apple Watch keeps your favorites in sync and plays from your wrist, even without your iPhone nearby. Headphones required throughout.
Also: widget, quick actions (long-press the app icon), Lock Screen and Dynamic Island controls, AirPlay, Siri and Shortcuts, dynamic app icon, and full accessibility support — VoiceOver, Dynamic Type, Reduce Motion.
We don't track how you use the app or who you are. Optionally save completed Pauses to Apple Health — off by default, entirely up to you. Listening History syncs with iCloud if you want it to — off by default. Export your full history as a JSON file from Data & Privacy any time.
