The Polar H10 is the accuracy benchmark at $89. For morning wellness logging, studies show smartphone PPG comes remarkably close — at $0.
A clinical-grade chest strap vs. a phone camera. The data is the same; the friction is not.

Four things a $349 ring or a $30/mo strap can't actually give you back.
Your iPhone camera is a clinical-grade PPG sensor. Pulse uses it to read your heart in 60 seconds — no ring, no strap, nothing else to remember.
Wearables forget you exist when the battery dies. Your iPhone has 80% at 7 a.m. — that's all the runway Pulse needs.
No cloud upload. No "anonymous" research-partner data deal. Just your iPhone, your numbers, and the Apple Health vault you already trust.
That's the lifetime cost of a Whoop subscription. Pulse charges you once — never. Every metric they measure, we measure. For free.
Download Pulse Rate and take a reading in the next 90 seconds. No card. No ring. No regret.
