Honest comparison
Tock vs Apple Health Sleep
Apple already tracks a sleep schedule, and with a Watch on your wrist it does considerably more than that. So the question is not whether Health is good. It is what is missing.
In short
If you wear an Apple Watch and you only want to see how long you slept, Apple Health already does it for free and does it better than any phone estimate. Tock adds the room: sound, snoring, a score, an alarm that can move earlier, and a coach that can explain what it found.

What Apple Health Sleep does better
Apple's built-in sleep schedule and Sleep Focus, with stage data when you wear a Watch to bed.
- It is free and already on the phone
- With an Apple Watch it produces measured stage data, which a phone on a nightstand cannot
- It is the system of record every other app reads from, including Tock
Runs on iPhone, Apple Watch. Tock is iPhone only, on iOS 26 and later.
Health is the record everything else reads from
Sleep Focus, a sleep schedule, and stage data when you wear a Watch to bed. It is free, it is already installed, and it is the system of record every third-party app reads from, Tock included.
Nothing here argues against that. Tock reads sleep, heart rate, resting heart rate, HRV, blood oxygen, respiratory rate and wrist temperature straight out of Health, and can write its own nights back if you turn that on. It is off by default.
Without a Watch, Health mostly records a schedule
That is the gap. A sleep schedule tells you when you intended to be in bed. It does not tell you that you snored for an hour, that the room got loud at 2am, or that you talked in your sleep.
Tock listens all night with the microphone and reads movement from the accelerometer, classifies snores, coughs and sleep talking on device with Apple SoundAnalysis, and keeps clips you can play back. It also builds 21 metrics in 7 groups over time, including a sleep regularity index and a chronotype from the rMEQ questionnaire in onboarding.
On phone-only nights Tock's stages are estimates. With a Watch, the measured stages in Health are better, and Tock will show those instead.
A schedule cannot move your alarm, and Tock can
A Sleep schedule wakes you at the time you set. Tock watches the last 30 minutes before that time for a lighter moment and rings a little early when it finds one, with your set time as the fallback. It is built on AlarmKit, so it rings on silent, through a Focus, with the app closed.
Then it holds one of nine wake-up missions in front of the off button until you solve something.
Where the two sit together rather than against each other
This is the least adversarial comparison on the site. Health stays the record. Tock reads it, adds what a phone in the room can hear, and takes over the alarm. If you turn on writing, Tock's nights land back in Health for everything else to read.
| What we compared | Tock | Apple Health Sleep |
|---|---|---|
| Price | From $39.99 a year | Free with your iPhone (stronger here) |
| Measured stages | Estimates without a wearable | Measured with an Apple Watch (stronger here) |
| Sleep Focus and schedule | Reads it, does not replace it | Built into iOS (stronger here) |
| Where your nights live | Health, if you turn writing on (about the same) | Health, by definition (about the same) |
| With no wearable | Sound, movement, a score (stronger here) | Mostly a schedule |
| Moving the alarm | Up to 30 minutes earlier (stronger here) | Fixed wake time |
| Explaining last night | A coach that reads your nights (stronger here) | Charts you read yourself |
Which one you should actually pick
Pick Tock if
Add Tock if you sleep without a wearable, or you want the alarm to move, or you want to hear what the room did while you were out.
Pick Apple Health Sleep if
Stick with Apple Health alone if you wear a Watch to bed, you are content with duration and stages, and you already like the alarm you have. It is free, it is measured rather than estimated, and it is the source Tock would be reading anyway.
Run both if
This is the normal setup. Health keeps the record, Tock adds sound and the wake-up, and the two stay in sync through Health.
Questions people ask
Does Tock replace Apple Health?
No, it reads from it. Health stays the record, and Tock can write its nights back there if you switch that on. The setting defaults to off.
Will my old Apple Health sleep data show up in Tock?
Yes, once you grant read access. That is the one migration on this whole site that actually works properly, because Health is shared ground.
If I wear an Apple Watch, do I still need Tock?
Not for stage data, which the Watch measures and Tock only estimates on its own. You would be buying the alarm, the sound classification, the missions and the coach.
Can Tock use the Sleep Focus I already have?
Tock ships a Focus filter and reads your Health data, and it does not ask you to tear down your existing Sleep schedule to work.
If Tock is not in the running
Plenty of people land here already choosing between two other apps. These go through those pairings without us in them.
Other comparisons
The same treatment, applied to the rest of the category.
- Tock vs the iPhone Clock appIf you want an alarm and nothing else, keep the Clock app. Tock rings on the same Apple framework it does, so the reliability argument is a draw. Tock is only worth paying for if you want the night before the alarm to change when it goes off, and you want a morning report and a mission before it stops.
- Tock vs AutoSleepIf you wear an Apple Watch to bed and you already have an alarm you like, AutoSleep is hard to beat and you pay for it once. Tock makes sense if you do not want to sleep in a watch, or you want the alarm and the tracking to be the same app.
- Tock vs PillowStay with Pillow if you track on your wrist, because it runs on the Watch and Tock does not. Choose Tock if your phone is the only thing on the nightstand and you want the alarm to be the centre of the product rather than a feature of the tracker.
- Tock vs Sleep CycleSwitch to Tock if you want the alarm itself to be different: a system alarm that rings on silent and through a Focus, moved up to 30 minutes earlier into a lighter moment, with a task before it stops. Stay with Sleep Cycle if you have years of history in it, or if someone in the house is on Android.
Elsewhere on the site
A different corner of the same problem.
- Tock for youEarly risersYou are up before your alarm most days, lying there working out whether to get up or risk another twenty minutes. On the days you go back to sleep, you feel worse than if you had just got out of bed.
- RoundupsThe best alarm clock apps for iPhoneFor most iPhone owners the best alarm clock app is the one already installed. The Clock app is free, reliable and enough. Tock is the upgrade worth paying for once the Clock app stops working, which usually means you dismiss it without remembering or you wake up feeling wrecked every morning.

- Sleep by ageHow much sleep adults needThe American Academy of Sleep Medicine recommends that adults sleep 7 or more hours per night on a regular basis to promote optimal health. It is expressed as a minimum rather than a range because the evidence supports a lower bound far more firmly than it supports an ideal figure.
- NapsThe 90 minute napA 90 minute nap is approximately one full sleep cycle, which means it ends in a lighter stage rather than in slow wave sleep. That produces much less grogginess than a 30 or 60 minute nap, and it includes both the deep sleep and the REM that shorter naps miss.
The alarm is the part we actually rebuilt
Tock rings on silent and through a Focus because it is a system alarm, moves earlier when it finds a lighter moment, and asks for one small task before it stops.
