PowNap wakes you when your body is ready.
Power naps on Apple Watch — guided by heart rate, not by time.
PowNap
Wake up when your body is ready.
PowNap is an intelligent power-nap timer for Apple Watch.
Instead of rigid time rules, PowNap uses your heart rate to detect recovery and wake you at the right moment.
You start the nap.
PowNap handles detection and wake-up — based on your current physiology.
---
Two Modes
Power Nap
15, 20, or 25 minutes.
- May end earlier if your body recovers sooner
- Ends at the selected time at the latest
Heart-rate detection with a fixed upper limit.
Infinity Nap
No time limit.
- Ends when your body shows signs of recovery or light sleep
- Ideal for stress, exhaustion, or when you don’t want a fixed duration
Not designed for deep sleep, but for short, measurable recovery.
Depending on your heart rate, this may happen after 10–15 minutes — or later.
---
Calm. Precise. Distraction-free.
- Detects relaxation and falling asleep via heart rate
- Wakes you with gentle vibration
- No countdown pressure, no unnecessary sound
- Subtle progress indicators instead of a classic timer
- Runs fully offline on your Apple Watch
Tap “Start” — PowNap takes care of the rest.
---
Adjustable (Optional)
- Vibration: Soft, Medium, Strong, or Increasing
- Heart-rate threshold:
- automatically adjusted to your resting heart rate
- or manually set as a percentage
Behavior may vary slightly depending on your daily condition.
---
Private & Local
- One-time purchase — no subscription
- No ads, no account, no tracking
- No cloud
All processing happens locally on your watch.
Saving naps to Apple Health is optional.
For heart-rate detection, Health permissions (Workout, Heart Rate, Sleep) are required.
Without them, heart-rate-based nap control is not available.
---
Important Notes
- PowNap is not a medical device
- For continuous heart-rate tracking, PowNap uses a “Mind & Body” workout session (required by watchOS)
As a result, exercise minutes are counted and Activity Rings are affected.
This behavior is system-controlled and cannot be undone.
---
Buy once.
No conditions.
Just calm, focused recovery.

Short FAQ
Why does PowNap start a workout?
- watchOS only allows continuous heart-rate tracking during an active workout.
Does PowNap fake activity or calories?
- No. All values come directly from watchOS.
Does PowNap affect Activity Rings?
- Yes, while the workout is active — this is system behavior.
Infinity = deep sleep?
- No. Infinity Nap is for short recovery, not deep or long sleep.
