Heart Alert connects to your Bluetooth heart rate monitor and plays a sound the moment your BPM goes above or below the range you set. Choose a minimum and a maximum, put your phone away, and train by ear. No screen-watching. No zone math. No account. ## How it works 1. Put on your Bluetooth heart rate monitor or chest strap. 2. Set your min and max BPM. 3. Press start — you get an alert when you drift too high or too low, and another one when you are back in range. ## Features – Custom minimum and maximum BPM limits – High heart rate alerts and low heart rate alerts – Immediate audio alerts, with adjustable volume – Optional vibration – Repeat interval of 1, 3, 5 or 10 seconds while you are out of range – "Out of range for" delay, so a short spike or a passing dip stays quiet – Initial delay, to keep things silent during your warm-up – Sensor battery level at a glance – Runs in the background while you use another app – Fast setup, nothing to sign up for ## Works with your heart rate monitor Supports most compatible Bluetooth Low Energy (BLE) heart rate monitors, chest straps and armbands, including: – Polar H10, H9, H7, OH1 and Verity Sense – Garmin, Wahoo TICKR, CooSpo, Scosche, Decathlon and more Any sensor that broadcasts a standard Bluetooth LE heart rate signal should work, though Bluetooth on its own does not guarantee compatibility. If yours is not detected, send the developer a message. An external heart rate sensor is required. Camera-based and wrist-only phone measurement are not supported. ## Made for – Zone 2 work and aerobic base building – Running, cycling and indoor cycling – Cardio, gym sessions and interval training – Endurance and steady-state efforts – Easy recovery days, where the whole point is keeping the effort down – Anyone who wants a heart rate alarm and nothing else ## Why an alarm instead of a display? A number on a screen only helps if you look at it. An alert means your target range takes care of itself, and you only think about it when something actually needs attention — on the treadmill, on the road, or with your phone in a jersey pocket. ## Pricing Your first 5 tracking sessions are free. Unlimited tracking is a one-time purchase. No subscription, no ads. ## Privacy Heart Alert has no internet permission at all. Your heart rate never leaves your phone. ## Important: background use The app keeps tracking in the background, but Android may shut it down to save battery.

It is not a medical device, it is not intended to diagnose, treat, cure or prevent any disease, and it should not be relied on for emergency or continuous health monitoring. Check with a doctor if you have questions about your heart rate or your training.
