Flow Harmony

Flow Harmony creates a simple, quiet space for focus. Open the app and Rain begins gently — no account, download, or setup required. Choose from four bundled natural sounds: Rain, Ocean, Fire, and Wind. Pause instantly, adjust the in-app volume, or set a timer for a focused session. Background playback and lock-screen controls let the sound continue while you use another app or put your device away. Flow Harmony works offline. It has no advertising, analytics, tracking, or account. Optional gifts support future improvements but do not unlock features; every sound and focus tool remains available to everyone. Flow Harmony is a focus aid, not medical treatment or medical advice.
