Comments on Sleep Cycle: Sleep Tracker for Android

★★★★☆ Adam Smith · Oct 9, 2026
I really like the app, and do find it helpful to wake up less tired and groggy especially when doing early mornings (4/5am wake up times for me) and there's a good few positives about it. If there's anything I'd like is, when tagging the noises it records, it's not clear what I should tag some as, for example bird noises of outside, I tag as other, but it'd be nice to have the option for bird noises (I know I can do manually, but that wouldn't mean sleep cycle does anything with the data.
★★★★☆ Ian Duarte · Sep 4, 2026
I've been using this app for 4 years and always loved it, but now I'm deeply disappointed, because they discontinued the ALERTNESS TEST, which was one of the best features of the app! What's the point of doing this? I'm sad...
★★★★★ Uche Nwaiwu · Sep 21, 2026
A good experience, using the alarm I have always woken up on time never late cause it times when one is no longer in deep sleep and sets on the alarm and the data it provides is detailed
★☆☆☆☆ Luis Meza · Aug 20, 2026
They would not give me a refund on the day the free trial ended and the yearly billing cycle started.
★☆☆☆☆ Yvette Quintanilla · Aug 8, 2026
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.
