A nap timer for your wrist
Sleep first.
Count down second.
Choose a duration. Daydream, rest, or drift off. Siesta estimates when sleep may begin from your heart-rate trend, then starts the countdown.
A fail-safe wake is set the moment you start — even if sleep detection never triggers.

Wake gently
Soft haptics bring you back when your nap is done.
Your watch does the work.
Siesta estimates sleep onset from heart-rate trends on your watch. It cannot detect daydreaming or sleep stages; very still, relaxed wakefulness may resemble sleep and start the countdown early.
Heart-rate samples are processed on the watch and discarded after each session. No account. No ads. No analytics. No backend.Sleep detection is an estimate, not a medical measurement.
