About
A breathing app built for simplicity
Souffle guides you through daily breathing exercises designed to help you sleep, calm down, or focus.
Why Souffle?
No subscription, no account, no fluff. Souffle gets straight to the point: helping you breathe mindfully, at the right pace and with the right atmosphere.
Features
Choose from 4 preset programs — 5-5 cardiac coherence, 4-7-8 for sleep, deep relaxation, and box breathing — or create your own custom program by adjusting duration, rhythm, and phases.
Every session comes with synchronized haptic feedback and a floral animation that visually guides your breath. Add one of 13 soundscapes — rain, deep forest, ocean, fireplace, brown noise — for full immersion.
Your progress is tracked automatically: practice streaks, session history, and mindfulness minutes recorded in Apple Health.
Built natively
Souffle is built in SwiftUI with SwiftData for local persistence, AVFoundation for soundscape playback, and CoreHaptics for vibrations. No data ever leaves your iPhone.
