Head to head
Headspace Sleep vs Pzizz
Neither of these apps knows whether you slept. Both stop at the moment you drift, so the choice is purely about what you want in your ears on the way down.
In short
If you nap in the afternoon, or you get bored hearing the same track night after night, Pzizz. If you want to be taught how to wind down and to still be doing it in three months, Headspace Sleep.
Headspace is trying to change your evening, not just fill it
The sleep content in Headspace sits inside a course structure. There are sleepcasts and sleep music, but they arrive with teaching attached and in an order, which is the difference between having something to play and learning a routine you keep doing.
It also runs guided wind-down exercises with a voice walking you through them. Some people need exactly that. Others find being instructed at 11pm the opposite of relaxing, and there is no point pretending that is a small difference.
Pzizz owns the nap and the never-the-same-twice trick
Pzizz assembles music, voiceover and effects into a session rather than playing a file, so it does not wear thin the way a recording you have heard fifty times does. If repetition is what breaks a sleep app for you, this is the direct answer to it.
Its nap module is the best-designed thing of its kind, and nothing else in this comparison comes close. If you nap and take that seriously, the decision is made.
Both leave the morning entirely to you
Neither app rings, and neither one records anything about the night. That means neither can tell you whether the wind-down helped, whether you woke at 3am, or whether the nap ran long.
For people whose only problem is the hour before bed, that gap costs nothing. For anyone trying to work out why their sleep is bad, it is the whole missing half.
Both are audio products. Judge them on what you want to hear, not on data they were never built to collect.
| What we compared | Headspace Sleep | Pzizz |
|---|---|---|
| Afternoon naps | Not built for them | The best part of it (stronger here) |
| Repeating itself | Fixed recordings | Different every session (stronger here) |
| Learning a routine | A course, not a playlist (stronger here) | Press play and go |
| Quality of the teaching | Genuinely good (stronger here) | Not what it sells |
| A voice you follow | Guiding you through exercises (about the same) | Voiceover woven into audio (about the same) |
| What it knows about your night | Nothing at all (about the same) | Nothing at all (about the same) |
Which one to actually install
Pick Headspace Sleep if
Headspace Sleep is the better long-term purchase if you want structure, teaching and a voice guiding the wind-down, and if you will use the wider meditation content too.
Pick Pzizz if
Pzizz is the better purchase if you nap, or if you want sleep audio that is assembled fresh each time so it never gets stale.
Pick neither if
If you want the audio and an actual morning, neither of these covers it. Tock has a silent wind-down, sounds generated on the device so they never loop, and an alarm that waits for a lighter moment before it rings. iPhone only, from $39.99 a year after a 3-day trial.
Questions people ask
Does Headspace Sleep include an alarm?
No. Headspace has no alarm and no tracking, so it only ever covers the front half of the night. You will still need something else to wake you.
Is Pzizz good for anything other than naps?
Yes, it does full-night sessions as well. The nap module is just the part that has no real competition.
Which is better if I hate being talked at?
Neither is ideal. Headspace is instruction-led and Pzizz threads voiceover through the audio. If you want sound with nobody talking, you are looking at the wrong pair.

- Calm vs Headspace SleepIf you want to be told a story by a voice you recognise, Calm has the deeper and better-produced library. If you want to be taught a wind-down and nudged to keep at it, Headspace's course structure does more for you.
- Calm vs PzizzIf you nap, or if hearing the same recording twice ruins it for you, Pzizz is the better buy. If you want big-name narrators and a library that carries you through the daytime too, Calm is the deeper product.
Elsewhere on the site
A different corner of the same problem.
- NapsThe 60 minute napA 60 minute nap includes a substantial amount of slow wave sleep, which is useful for recovery and for some kinds of memory, and it usually ends before the cycle completes. That means the benefit is real and the wake-up is often groggy, so it suits situations where the hour afterwards is flexible.
- Wake tonesMusic boxMusic box is Tock's slowest and most nostalgic wake tone, a thin bell-like melody that unwinds instead of alerting. It rings reliably through silent mode because Tock's alarms run on Apple's AlarmKit, but as a tone it is the weakest choice in the set for anyone who genuinely sleeps hard.
- FeaturesApple HealthTock reads Apple Health for sleep, heart rate, resting heart rate, HRV, blood oxygen, respiratory rate and wrist temperature, and shows them on the night they belong to. It can also write its own nights back into Health, but that setting defaults to off.
- Sleep soundsBrown noiseBrown noise puts almost all of its energy in the low end, dropping roughly 6 dB with every octave you climb, so it reads as a rumble or distant surf rather than a hiss. That low weight is exactly why it covers traffic, footsteps and a neighbour's bass better than white noise does, and also why it can feel like pressure if your room is already quiet.
- Tock for youLight sleepersYou wake at everything, and then you are awake for forty minutes at 3am doing arithmetic on how much is left. By morning you cannot say what woke you, only that something did, several times.
- AlternativesTock vs Headspace SleepHeadspace Sleep is the better choice if you want a voice walking you through a wind-down inside a proper course structure. Tock is the choice if you want the night measured from the phone and an alarm that moves into a lighter moment. Neither one covers the other.
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.
