WhatsHeart is a unique Android application that provides heart rate tracking, audio statistics during training, GPS tracking, and workout analysis. This free app stands out from other similar applications in terms of convenience and practicality. WhatsHeart offers continuous voice notifications of heart rate and can work 24/7, even when the smartphone screen is turned off or locked, or when the smartphone is switched to another program.

One of the key features of WhatsHeart is the real-time output of heart rate to the smartphone screen. It also provides alerts when the heart rate goes beyond the selected interval, using voice, sound, and vibration notifications. The app displays heart rate charts, GPS tracks on a Google map, and records workouts along with heart rate and GPS track data.

WhatsHeart also offers audio statistics "by time" and "by distance" through voice messages. Users can create lists of required parameters such as pulse, pace, distance, and time, and these values are periodically reported during training. The app also provides tables and graphs showing the distribution of training time by pulse zones.

In addition, WhatsHeart automatically calculates Max heart rate values based on age and heart rate at rest, and forms pulse zones such as Anaerobic and Aerobic. It also calculates calories based on heart rate or the type of training using MET (metabolic equivalent of task).

Please note that WhatsHeart is not a medical app and does not record ECG.
