HeartQ: Heart Rate Monitor

Your heart, explained. HeartQ turns a 30-second camera reading into something you can actually use: your pulse, your heart rate variability, and what they suggest about your stress and recovery today. MEASURE WITH YOUR CAMERA Rest a fingertip on the camera. HeartQ uses the lens and flash to estimate your pulse and HRV — no strap, no watch, no extra hardware. SEE YOUR HRV PROPERLY Both SDNN and RMSSD, not a single mystery number. Watch them move over days and weeks instead of guessing. STRESS AND RECOVERY A stress score and a recovery state drawn from your own readings, so you can tell a demanding day from a depleted one. BREATHE IT DOWN Guided sessions that are actually paced: Box 4-4-4-4, 4-7-8, and Coherent breathing for slow, even rhythm. Start one the moment a reading comes back high. BLOOD PRESSURE LOG Record systolic, diastolic and pulse, and HeartQ organises them with pulse pressure, MAP and a clear classification. Add context in notes — posture, cuff size, how you felt. BLOOD OXYGEN LOG Keep your SpO₂ readings in one history, with an optional symptom tracker for dizziness, breathlessness, fatigue and more. TRENDS WORTH READING Charts across days, weeks and months, so a single odd reading stops looking like a crisis. DOCTOR-READY PDF Export a clean report of your history to share at an appointment or keep for yourself. APPLE HEALTH Connect to Health to keep your readings alongside the rest of your data. ASK QUESTIONS A built-in wellness assistant for the things you would otherwise search for at midnight — what HRV means, why a reading moved, what a number does and does not tell you. HOW IT WORKS, IN THE OPEN HeartQ shows its methodology: what each metric is, how it is calculated, and the sources behind it. You should know where a number comes from before you trust it. SPEAKS YOUR LANGUAGE Available in 14 languages, chosen inside the app. IMPORTANT HeartQ is a wellness and fitness app, not a medical device. Pulse and HRV are camera-based estimates. Blood pressure and blood oxygen are values you enter yourself — HeartQ records and organises them, it does not measure them. Nothing here diagnoses, treats or prevents any condition, and no reading should replace professional medical advice. If something concerns you, talk to a clinician. Some features require a Premium subscription. Pricing and duration are shown in the app before purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the period ends, and can be managed in your Apple Account settings.
