HRM Benchmark - Wrist HR vs chest HRM
Compares your watch's wrist heart rate with a chest strap at the same time, showing in numbers how closely they agree and how quickly the wrist follows when your heart rate rises. The strap connects to the app directly. Free.
Strong: original idea, runs on most watches. Weak: too few reviews to judge (0).
Originality: wrist vs chest heart rate test
