About Sereo: Breathe & Calm Down
Sereo is the screen-free reset for your nervous system — a discreet, 90-second way to calm down anywhere, even in the middle of a meeting. No library to browse. No reading. Pick one of three intents — Calm, Focus, or Sleep — close your eyes, and breathe. Sereo guides every inhale and exhale with a gentle haptic tap on your iPhone or Apple Watch, so you can regulate with your phone still in your pocket. WHY SEREO IS DIFFERENT • Adaptive pacing, not a fixed timer. Sereo reads your live heart rate from your Apple Watch and actively decides how fast to slow you down, so each session meets your real state. • Built for discreet, everyday use. Pocketed and eyes-closed is the primary mode — regulate without anyone noticing. • Feel each breath on your wrist. Distinct haptic inhale and exhale cues on Apple Watch. • See your nervous system shift. A one-line recovery readout after every session shows how far you settled. FREE All three intents, full haptic and ring sessions, heart-rate-adaptive pacing, and the recovery readout for your current session. SEREO PRO • Settling-score trends over weeks • Custom breath ratios and new intents • Focus-mode and Shortcuts automations • Personalized pacing targets Sereo Pro is available as a monthly or annual subscription, with a free trial on the annual plan. Payment is charged to your Apple ID; subscriptions auto-renew until cancelled, and you can manage or cancel anytime in Settings. Sereo makes no medical claims and is not a substitute for professional care. Your heart-rate and session data stay on your device.
