Head to head

Apple Health Sleep vs Pillow

Apple already tracks your sleep, which makes the case for a second app harder than it was a few years ago. Pillow still has one.

In short

Apple's built-in tracking is enough if you want hours and stages and nothing more. Pillow is for the Watch wearer who finds Apple's presentation too thin and wants the night detected and shaped for them without pressing anything.

Try for freeiPhone, iOS 26 and later. From $39.99 a year with a 3 day trial.

Apple's version is the floor, not the ceiling

With a Watch on your wrist, Apple gives you measured stage data for free, in the app that every other sleep app on your phone reads from. That's a strong floor, and it's why the bar for a second app is higher than it used to be.

What it doesn't do is interpret. You get the night, plainly, and you're left to decide what it means.

Automatic detection matters more than it sounds

Pillow works out when you fell asleep without you starting anything. That sounds like a small convenience until you count the nights you'd have forgotten, and a tracker you forget to start is a tracker with holes in its history.

It also ships a real Apple Watch app, so the tracking happens on your wrist rather than being inferred from somewhere else.

Round-tripping Health data is the quiet reason people switch

Pillow reads from Apple Health and writes back into it properly, in both directions. If you've got years of Health data you care about, that matters more than any chart on the screen.

It also runs on iPhone, Apple Watch and iPad, which is one more place to look at the night than Apple's own setup gives you.

Apple Health can hold data from more than one source, but two apps writing the same night can look messy. Pick one writer.

Neither of these is the thing that wakes you

Both describe the night. Neither is built to ring at the end of it. Tock is an iPhone alarm first, built on AlarmKit so it fires on silent and through a Focus with the app closed, and its tracking exists to move that ring into a lighter moment.

Tock has no Apple Watch app of its own. It reads your Watch data through Apple Health.

Which one to actually install

Pick Apple Health Sleep if

Stay with Apple if hours and a stage chart answer your question. It's free, it's already running, and anything else you install is going to read from it anyway.

Pick Pillow if

Pillow is the upgrade if you want the night caught without starting it, a Watch app of its own doing the work, and results written back into Apple Health thoroughly rather than dumped there.

Pick neither if

If what you actually want is the alarm to know what the night was doing, neither of these is that. Tock rings on AlarmKit so the alarm survives silent mode and a Focus, tracks from the phone on your nightstand, and can move the ring a few minutes earlier into a lighter moment. A 3-day trial, then from $39.99 a year.

Questions people ask

Do I still need Apple Health if I use Pillow?

You do, and Pillow wants you to. It writes into Health, which is where the rest of your data lives and where anything else you install will look for it.

Does Pillow work without an Apple Watch?

Some of it, but you lose the part people recommend it for. The Watch app and the automatic detection are the reasons to pick Pillow over what Apple already gives you.

Are phone-only sleep stages as good as Watch stages?

No, and no honest app claims otherwise. A phone on the nightstand estimates the shape of your night. A Watch on your wrist measures signals from your body.

Will running both double-count my sleep?

Health can hold several sources, but two apps writing the same night makes for a confusing chart. Let one write and the other read.

If neither of them is quite the alarm you wanted

Tock is built on Apple AlarmKit, so it rings on silent and through a Focus, moves earlier when it finds a lighter moment, and keeps ringing until you solve something.
