Smartphone apps accurately measure human heart rate

the verdict
SUPPORTED
the evidence backs this
Recorded sources
4 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that smartphone apps accurately measure human heart rate?

Yes. Multiple validation studies demonstrate that smartphone applications utilizing photoplethysmography (PPG) via built-in cameras can measure human heart rate with high accuracy compared to electrocardiography (ECG) reference standards.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

The retrieved papers consistently provide strong empirical validation across various settings (contact fingertip PPG and contactless facial vPPG) showing that smartphone apps measure heart rate accurately compared to standard ECG or oximeter references. No papers refute the claim.
