Key result
Contact photoplethysmography-based apps had better accuracy for heart rate measurement (mean absolute error 2-4.5 bpm) than non-contact apps (7.1-8.1 bpm) compared to electrocardiogram.

Do smartphone apps accurately measure heart rate compared to electrocardiogram in clinical practice?
Contact photoplethysmography-based smartphone apps offer better accuracy for heart rate measurement than non-contact apps.
Coppetti et al. (2017) reported an observational. Smartphone apps for heart rate measurement vs. Electrocardiogram and pulse oximetry was evaluated on Accuracy of app-measured heart rate compared to electrocardiogram (mean absolute error in bpm). Contact photoplethysmography-based apps had better accuracy for heart rate measurement (mean absolute error 2-4.5 bpm) than non-contact apps (7.1-8.1 bpm) compared to electrocardiogram.
