Comments on Sleep Cycle: Sleep Tracker for Android

★★★★★ Raj Sutaria · Mar 25, 2026

Not kidding but app really works to wake you up in amazing manner that you do nit feel asleep after wake up. Because of their patent technology it worked for me. I was struggling to wake up very early in morning but not able to wake up, tried many apps, but none worked perfectly. Watched sleep cycle app on YouTube recommendation and give it a try, and it worked very 100% perfectly. Hats off to developers and engineers of this app. Loved this app so much. Thanks !!

★★★★☆ Becca Proschko · May 24, 2026

Insightful as to how my sleep effects my overall moods each day. Still loving this app. However, needing help with the time report often coming up as Multiple time logs. Instead of showing from hour to hour I guess it's adding minutes in-between making it one Huge Long cluster of data I am not able to comprehend. I have tried looking in settings for something that could change this to Normal hour to hour logging of noises n all sleep habits but no luck so far. I obviously do not know...

★★★★★ Aditya Jadhav · Feb 26, 2026

Great idea to wake up during light sleep 💡 😁, would be even better if it allowed custom songs at free ✅

★☆☆☆☆ Samer Saffarini · Mar 18, 2026

Turned the smart alarm into a premium feature after years of offering it for free. Uninstalled.

★☆☆☆☆ Q Maulidiar · Mar 24, 2026

I use it mainly for the smart alarm, while the sleep tracker is neat and all but I don't really care about that. What made me decide to give this a one stat is because they decided it was smart to make a core feature locked behind paywall.

★☆☆☆☆ Brittanie Blake · Apr 13, 2026

I canceled my trial, and was still charged for a yearly premium subscription. Would not recommend.
