Head-to-head duels
All reviews (10)
Sleepio
The most clinically serious app here — a validated CBT-I course that treats insomnia, not a tracker or a sound library; the strongest pick if you have a real sleep problem.
Sleep Cycle
The most polished mainstream sleep tracker — a smart alarm and clean analysis, with a genuinely useful free tier.
SleepScore
A research-led, contact-free tracker — the strongest here at turning your sleep data into something to actually act on.
Sleep as Android
The most complete sleep app on Android — tracking, smart alarm and wind-down sounds in one — if you do not mind a feature-dense interface.
BetterSleep
The richest wind-down library of any sleep app — soundscapes, stories and meditations — with light tracking bolted on; a relaxation app first, a tracker second.
Pillow
A detailed, well-presented sleep tracker for the Apple Watch — excellent if you are on iOS, irrelevant if you are not.
RISE
A sleep app that reframes the goal as daytime energy — it tracks sleep debt and your circadian rhythm and tells you when to do things, not just how you slept.
Pzizz
A focused sleep-audio app — its algorithm builds a fresh soundscape every night so it never gets stale — but it does one thing only and does not track.
AutoSleep
The purist Apple Watch sleep tracker — accurate, automatic and subscription-free — but it only measures sleep, it does not help you get it.
Endel
An AI soundscape app that adapts its audio to time of day and inputs in real time — beautiful and distinctive, but it plays sound, it does not track sleep.
