Editors' Notes

When your alarm goes off in the morning, is your first reaction to throw it against the wall? The problem isn’t with you—it’s with your alarm clock. Thankfully, Sleep Cycle offers a clever solution for improving your rest. Rather than yanking you from your slumber at a specific minute, the app analyses your sleep patterns and then picks the moment you’re sleeping lightest (within a half-hour window you define) to rouse you gently. Best of all, unlike some smart alarms, this one doesn’t need extra hardware or require your device to be resting on your bed: it tracks your sleep using just its microphone!

The best alarm clock app out there!

This has been the best alarm application out there. and it honestly does the work as described. I was introduced to the app by one friend back in 2015. since then, this app is on my “must have app” even if i am running low and space. but somehow this time space isn’t the issue. Issue is, that it drains my mobile battery real quick. in 6 hours when I am asleep, it drains my phone battery from 100 to 18%. This never happened to my iPhone 5, but now in iPhone 7. I don’t like to keep my phone connected to power all time when I am asleep, due to over charging and stuff. Kindly resolve the issue, and take 5!

Developer Response ,

Hi! Please make sure that you haven't set an alarm in the default Clock app on the phone. Also check the tab 'Bedtime' in the Clock app as well.
Note that we have a battery warner as well, if the battery of the phone is about to discharge an alarm will sound. 

All the best, Nora
