User Reviews

Users praise the app for solid sleep tracking and an effective smart alarm when accessible, and note its long-running reliability. However, widespread paywalls locking core features, intrusive ads, and occasional tracking inaccuracies drive dissatisfaction and uninstallations.

Pros

Good sleep tracking accuracy and a neat sleep tracker
Smart alarm can wake you up smoothly and effectively when the feature is accessible
Longstanding app with many users using it for years (over a decade)

Cons

Smart alarm and other core features are locked behind a paid subscription/paywall, causing dissatisfaction and uninstallations
Intrusive ads and notification ads, especially affecting free users
Inconsistent sleep tracking accuracy (misreads wake times or time to fall asleep)
Recent updates reduced free functionality (e.g., removing wake windows) leading to frustration

this thing records me 24h ... just found out all my conversations are recorded even during the day.

Al*****, 2026-08-28

it is a good app. the only thing is that it doesn't see if you are still asleep even after your alarm goes off to wake you up. I have had it a few times now where I wake up from the alarm, turn it off and go back to sleep. it doesn't spot i am still sleeping therefore doesn't track it through my watch. if a feature could be added where it can tell through your watch if you are asleep or not would be super useful. I have also had it where I forget to turn the alarm on before bed.
