WHY PEOPLE USE SERENO
Real-time stress monitoring
Sereno helps you notice stress while it is happening, not only after the day is over.
Apple Watch and Health insights
Connect Apple Watch and Apple Health to turn HRV, heart rate, resting heart rate, sleep, steps and workouts into readable stress signals.
AI stress explanations
Sereno turns your physiology into plain-language insights, showing what changed, what may be driving the shift and what to try next.
Anxiety and panic support moments
When stress rises quickly, Sereno can surface a calmer next step with breathing and recovery guidance.
Weekly reports
See how stress, HRV, recovery, sleep and activity moved across the week, so patterns become easier to understand.
Doctor-ready summaries
Generate concise reports for appointments or personal tracking when you want a clearer view of your stress history.
BUILT AROUND YOUR BASELINE
Generic stress scores miss context. Sereno learns your personal baseline over time, so changes are compared against your own body instead of a one-size-fits-all number.
BUILT FOR PRIVACY
Sereno is designed for personal health reflection. You choose what to connect and what to share.
SUBSCRIPTION
Sereno offers optional premium access for deeper AI insights, weekly reports, doctor-ready summaries and advanced stress tracking features. Subscription details are shown in the app before purchase.
IMPORTANT
Sereno is not a medical device and does not diagnose, treat or prevent medical conditions. If you are experiencing severe anxiety, chest pain, thoughts of self-harm or a medical emergency, contact local emergency services or a qualified clinician.
