Review summary

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

2026-08-08	Yv*****	Does not accurately track your sleep or accurately record and label sounds during your sleep. I stopped using it and hadn't opened it since June. Now, in August, it set me up for an unauthorized monthly autopay of $70. I wouldn't know except that PayPal notified me. I had no way of getting in touch with the app people so PayPal helped me by canceling the subscription and refunding the unauthorized charge. Idek how they got my PayPal information. DO NOT TRUST THESE PEOPLE.

2026-08-08	Ri*****	It gives me a rough idea of how I sleep and how much I snore. However, it never seems to know when I wake up during the night, even when I get out of bed and go to the toilet. Also, it will say I fell asleep after X minutes, even if I'm laying awake for much longer than X minutes. I guess it is not truly able to tell when I'm awake as opposed to when I am laying still for several minutes.
