About this app

Halo Swell is a breathing coach app that guides you through structured inhale and exhale cycles using a smoothly animated expanding and contracting circle.

No account needed. No internet required. Everything works offline, right from the moment you open it.

Choose from a selection of breathing patterns designed for different goals — calming your nervous system, sharpening focus before a task, or winding down before sleep. Each pattern controls the timing of your inhale, hold, and exhale phases, displayed through a clean circular animation that expands and contracts in sync with your breath.

The interface is minimal by design. A large animated halo guides your attention during each session, so you can focus on breathing rather than navigating menus. Sessions run without interruption and without any sound — only optional haptic feedback pulses gently to mark phase transitions if you prefer a physical cue.

Dark mode is supported with light, dark, and system-synced options. All settings and session preferences are stored locally on your device.

Halo Swell is completely free with no purchases, no subscriptions, and no data collection of any kind.
