Saphere HBPM is a personal blood pressure logging app. It guides you through a structured 7-day measurement cycle and produces a clear summary you can share with your doctor.

TWO WAYS TO MEASURE
• Smartphone camera — place your fingertip on the camera lens; Saphere's PPG (photoplethysmography) engine extracts a reading from the optical pulse signal. No cuff required.
• Traditional cuff entry — already use a home cuff? Type in your readings.

7-DAY MEASUREMENT CYCLE
The 7-day cycle organizes your measurements:
• Two sessions per day — morning (6–10 AM) and evening (6–10 PM)
• Two consecutive readings per session, one minute apart
• Daily reminders for the next session
• Three cycle variants: Most Accurate, Balanced, and Quick Check

7-DAY SUMMARY REPORTS
At the end of each cycle, Saphere HBPM generates a PDF summary you can share with your doctor:
• Morning, evening, and overall averages
• Adherence summary across the seven days
• Visual trends and per-session breakdown

PRIVACY & SECURITY
• OpenID Connect authentication with PKCE
• Optional Google Sign-In
• Encrypted credential storage on device
• No third-party analytics, no advertising

IMPORTANT
Saphere HBPM is a personal logging tool, not a medical device. It does not provide diagnosis, treatment recommendations, or medical advice. Always discuss your readings and any treatment decisions with your doctor.
The camera-based measurement is intended for adult use; if you have an arrhythmia or take certain medications, follow your doctor's guidance.

LANGUAGES
English and French. Voice guidance during camera measurement follows your phone's system language.

BUILT IN METZ
