The science

Receipts before the pitch.

We will not ask anyone to wear a heart monitor on faith. Every claim below has a study, a sample size, and a comparator. If a line is not yet validated, we say so.

The science
backs it up.

Three numbers from peer-reviewed cardiac literature. Each one is the gap between a wearable that watches and one that warns.
