Hearty – Heart Rate, HRV & Stress Tracker
Hearty helps you understand your body using your smartphone camera. Measure your heart rate and explore Heart Rate Variability (HRV) insights to track stress, recovery, and daily readiness—no extra devices needed.
Simply place your fingertip over the rear camera and stay still while Hearty captures your pulse using optical sensing technology.
WHY HEARTY STANDS OUT?
Most apps only show heart rate (BPM). Hearty goes further by analyzing the variation between heartbeats (HRV), a widely used indicator for stress and recovery.
Instead of raw numbers, Hearty translates your data into simple, easy-to-understand insights so you can make better daily decisions.
