What makes BreathFlow different
Built for panic, not for calm people
Most breathing apps assume you can already breathe slowly. Panic SOS meets you at your real breathing speed (2s/2s) and decelerates over five minutes.
Haptic-first
Long-press to turn off the screen and let vibration guide you. For dark rooms, sensory overload, or moments you can't look at a screen.
No subscription. Ever.
All 12 techniques and the Panic SOS are free forever. No paywalls on what should be available the second you need it.
