Comments on Sleep Cycle: Sleep Tracker for Android

★★★★★ Hs Tan · Jul 23, 2026

This app is what I'm looking for. Last time I always used to wake up groggy but now with this app, I always wake up....REFRESHED

★★★★☆ 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...

★★★★★ Matthew Schwartz · Apr 5, 2026

This app WAS fine for years until you whack jobs decided that smart alarm would now be a premium feature, but that I could keep it for free if I logged in. So I did, and it turns out it's not free! It's still locked behind a paywall. Did I just hand some random company my health data on false promises? EDIT: it's back to how it was originally. Thank you, Sleep Cycle for listening. 5 stars for now.

★★★★★ Jun-Jun A · Jul 24, 2026

Monitors my sleep & Smart wake-up alarm are very informative and useful.

★★☆☆☆ Max Deike · Jul 23, 2026

The gentle alarm and sleep aids are great, but the tracker is trash. It can't truly distinguish sleep from wakefulness, relying on guesses than actual data. Have had and tested the app for a long time, it recorded me as "asleep" while I was awake or even out of bed, and failed to capture speech. The cycle tracking feels like a simple timer rather than analysis of actual sleep data. If you need a real tracker, look elsewhere; I encourage users to test the app for themselves and see the flaws.

★☆☆☆☆ Brittanie Blake · Apr 13, 2026

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

★☆☆☆☆ Samuel Jędrzejewski · Jun 13, 2026

Useless app, you cannot go to the toilet during the night because it assumes you are awake and cancels your alarm. Thanks for destroying my important visit
