Best Free Sleep Tracking Apps for Apple Watch (2026)
Apple’s built-in Health app is free with an Apple Watch. It tracks your sleep stages, heart rate and breathing rate and scores each night, but it has no smart alarm and records no sound. I make Snore Timeline, the free app I’d add, with no subscription, no trial and nothing locked. It turns your watch data into a recovery score against your own baseline, wakes you in light sleep with wrist taps, and records snoring you can play back. It picks up watch nights on its own, and it records audio.
Key takeaways
- Same data: each app turns the same watch data into its own score. I found no independent lab test of any of these scores.
- Automatic tracking: five of the six apps track on their own for free. Sleep Cycle charges for it.
- Free-tier catch: Pillow and Sleep Cycle make you start a Premium trial before the free version opens.

At a glance
An app counts as free here if it does something useful with the watch without a purchase. Apple’s built-in Health app gets its own section.

|---|---|
| AutoSleep | $9.99 up front; compared in AutoSleep alternatives |
| Rise | No free plan; the trial needs a card |
| Athlytic | Only a 7-day trial is documented |
| NapBot | Full history and trends need PRO; last updated Sep 2025 |
What does Apple’s own Sleep app give you for free?
Turn on Track Sleep with Apple Watch and the watch records your night, no app or fee. Apple stages sleep from the accelerometer [6].
| Question | Answer |
|---|---|
| Sleep stages | Awake, REM, Core and Deep |
| Sleep Score | 0 to 100: duration 50, bedtime 30, interruptions 20 |
| Vitals | Heart rate and breathing rate against time asleep |
| Wrist temperature | Series 8 or later, any Ultra |
| Sleep apnea notifications | Series 9 or later, Ultra 2 or later, SE 3 |
| Smart alarm | No, a fixed-time alarm only |
| Records sound | No |
| Before it tracks | 30% charge, 1 hour asleep with the watch on |
The score covers three things and says nothing about what to change. That gap is where the apps come in.
What does each app tell you from the watch data?
The apps read the same wrist sensors. The morning answer differs.
| App | What it tells you | Free or paid |
|---|---|---|
| Snore Timeline | Recovery against your baseline; sleep score broken down by factor | Free |
| SleepWatch | Sleep score, guidance and which habits help | Premium |
| Pillow | Stages and heart rate range; then detailed analysis and trends | Partly free |
| Sleep Cycle | Sleep graph from wrist motion; then heart rate | Partly free |
| Bevel | Recovery, strain and stress scores; an energy bank | Free |
| Sleep++ | Readiness score; stages, heart rate and oxygen | Partly free |
Snore Timeline rates HRV, resting heart rate, breathing rate, blood oxygen, wrist temperature and time asleep against your own last 28 nights, and shows how long oxygen sat below 95%. When the watch has staged the night, the sleep score uses its Deep and REM over the audio estimate.
Will sleep tracking drain the battery?
Few reviews raise it: 95 of 2,768 recent sleep reviews I coded mention battery, mostly about rings. A SleepWatch reviewer (21 Jan 2026) went from 100% at bedtime to 27% by morning.
Snore Timeline records on the iPhone, so a dead watch costs only the wrist readings. Keep the phone plugged in; recording uses about 3 to 5% an hour, per the FAQ.
Wear a ring or a different watch?
Snore Timeline reads any device that writes sleep to Apple Health. Whether the data gets there free depends on the maker:
- Free: Garmin, with Connect open for the sync to run [33]. Google Health, the renamed Fitbit app. Polar, sleep times only [31].
- Paid plan first: Oura Gen3 and Ring 4 (Gen2 is exempt) [29]. WHOOP, which stops collecting data without a membership [30]. Withings accounts made on or after 13 October 2026.
- HRV gap: none of those writes HRV to Apple Health, so recovery uses what arrives, such as heart rate. An Apple Watch Series 8 or later writes all six.
- Stays behind: daytime activity, strain and readiness stay in the maker’s app. Galaxy Watch4 and later don’t work with an iPhone [32].
Membership prices are in sleep trackers with no subscription.

Which one to pick
- Pick Snore Timeline if you want recovery, a wrist-tap smart alarm and snoring you can hear, with audio stages on nights the watch charges.
- Pick Apple’s built-in Health app if you want tracking that starts on its own and sleep apnea notifications.
- Pick Pillow if you want its own stage analysis of your watch data.
- Pick Sleep Cycle if you want a free smart alarm timed from wrist motion on the watch.
- Pick Bevel if you want strain, stress and training next to your sleep.
No watch hears snoring; snoring apps for Apple Watch covers that.
Snore Timeline analyzes audio. It is not a medical device and does not diagnose sleep apnea or any other condition. If a score or a recording worries you, take it to a doctor.
Frequently asked questions
Is Apple Watch sleep tracking free?
Yes. Apple charges nothing for it, and Apple’s built-in Health app lists what you get and what it leaves out.
Do I need a third-party app if I have an Apple Watch?
Not to track sleep, which Apple does for free. You need one for a light-sleep alarm, recovery against your own baseline, or the sound of the night.
Why do two apps show different deep sleep from the same watch?
Some show Apple’s stages and others run their own analysis. Deep sleep is the hardest stage for any tracker to measure, so the numbers differ most there.
The watch died overnight. Is the night lost?
For watch-only apps, yes. Snore Timeline records on the phone, so only the wrist readings are missing.
