Photoplethysmography doesn’t work – Welltory: Heart Rate Monitor Review

If you’re looking for an app to measure your pulse/heart rate through the camera on your smart phone, don’t waste your time or money on Welltory. The readings I get never map on to what I can verify with other heart rate monitors, and often give me estimates that are double or even triple what my current heart rate is. This app is all shine and no substance. Do not buy the pro feature if you’re depending on the plethysmography for measuring!
