Simple Heart Rate Monitor app analytics for September 8

Launch, tap Connect, choose your sensor. Your heart rate is on screen in seconds. No account. No sign-in. No questions about your goals, your weight, or your training plan. No ads, no subscription, no notifications begging you to come back. You buy it once and it does the one thing its name promises. REQUIRES A BLUETOOTH HEART RATE MONITOR APPLE WATCH DOES NOT WORK! This app displays readings from an external Bluetooth heart rate sensor. It cannot measure your heart rate by itself, and it does not guess or estimate one from the camera. You need a chest strap, armband, or watch that broadcasts on the standard Bluetooth Heart Rate profile. That covers nearly every strap sold today, including sensors from Polar, Garmin, Wahoo, Coospo, Magene, Suunto, and Decathlon. WHOOP works once heart rate broadcasting is enabled in its own app. Apple Watch does not broadcast heart rate as a standard Bluetooth sensor and cannot be used with this app. ON SCREEN A large BPM readout, sized how you like it, in portrait or landscape. Average, maximum, and elapsed time, with one tap to reset all three. The screen stays awake while you are connected. ZONES Turn on the five-zone display and see which zone you are in at a glance, at 50, 60, 70, 80, and 90 percent of your maximum. Enter your maximum directly, or let the app estimate it from your age and sex using the Tanaka and Gulati formulas. If readings during a session exceed your current maximum, the app raises it for you. SPOKEN READINGS Have your heart rate read aloud every 30, 60, 90, or 120 seconds and train without looking at your phone. Works with the screen locked. SESSIONS Recording starts on its own when you connect and ends when you disconnect. Anything under a minute is discarded. Browse your history, drag along the graph to read any moment, and export a session as CSV for a spreadsheet or PDF for reading. PRIVATE BY DESIGN The app contains no network code. Nothing is uploaded because there is nowhere to upload it to. No analytics, no tracking, no third-party services, no permissions beyond Bluetooth. Your sessions are files on your phone, yours to export or delete. IMPORTANT Simple Heart Rate Monitor is a fitness and general wellness app. It is NOT a medical device. It is not intended to diagnose, treat, cure, or prevent any disease or condition, and it must not be used to make medical decisions. Age-based maximum heart rate values are estimates and may differ substantially from your own. Consult a physician before starting an exercise program, and seek medical attention for chest pain, breathlessness, dizziness, or an irregular heartbeat.
