Readiness, sleep and heart-rate insight from the strap you already own. On your phone. Yours to keep.
The app
Real screens, with a fortnight of readings behind them.
Daily use
No button to press, no session to start. Put the strap on, and in the morning your night is waiting for you.
A readiness score each morning, built from your own baseline — not a stranger’s average.
When you fell asleep, when you woke, how much you actually got. It notices on its own.
Every night kept on your phone. No account, no cloud, nothing that expires when you stop paying.
Compatibility
Yawp reads the standard Bluetooth heart-rate signal — the one nearly every strap of the last decade sends.
and most other Bluetooth chest straps and heart-rate monitors.
Privacy
There’s no account to make and no server holding your heart rate — because there’s no server at all.
If you want a backup, it goes to your own iCloud, the private part only you can open. It’s off until you switch it on.
Price
An app charging a subscription to escape subscriptions would deserve everything it got.
$0
Live heart rate and today’s numbers, with any strap you own.
$19
Sleep, trends, readiness and backup. Indicative price — not on sale yet.
Why trust it
The first night it recorded, Yawp found that its own heart-rate variability was twice the real figure — and it was fixed before anyone saw it. Every number in the app shows what it was worked out from, so you can tell a measurement from a guess.
