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!

I’ve always had trouble trying to get up in the morning from my normal alarm so I decided I’m just going to get a proper app. I was looking for some good app that will help me and I came across sleep cycle. It looked really good and had great features I tried it for the first few days and it was great!! I happily woke up in a light sleep and I actually was ready to get out my bed instead of my normal alarm which was insane!! I also love how as soon as you wake up if tells you have long you slept for unlike other sleep apps you have to wait along time just to find how long you slept that night?! Sleep cycle is just so easy to use and is absolutely great for people who have trouble waking up in the morning! Even though I don’t have the premium it still works great and fine! So I am very impressed with how great this app is! Question- Does sleep cycle still work even with people sleeping in the same room near your phone or can it mess up the cycle a bit hopefully not because I have roommates how like to snore and I hope that doesn’t affect anything!!😀 5 stars!⭐️⭐️⭐️⭐️⭐️

App can’t adjust to time zones

Generally this app is good, however I also use this as my alarm clock and it turns out the app cannot be trusted when you travel to other time zones. I have overslept because the app thinks I am in the old time zone and been late for my meetings as a result. On the return trip it has woken me up an hour earlier because it again struggles to adjust back to the change of time zones. Absolutely hopeless and it will take a long time to regain the trust in the app again.

App developer responded saying that the phone needs to be restarted in full to avoid this issue. Now I know how to resolve the flaw, but pretty poor resolution and I am pretty certain that most users will not have read my review and will not be aware of this issue / resolution. I would have expected the app developer to say that they will resolve the bug rather than putting the responsibility on to the user...

Hi there! If you change time zone, make sure to restart your phone to avoid any issues.
All the best, Nora
