Reviews for Sleep Cycle: Sleep Tracker

What an interesting tool! I have been trying it out a little over a week. I notice my deep sleep cycles are in regular pattern. I know not to set alarm for 6 AM because I'll feel bad all day from getting jarred out of a deep sleep. If I would need to readjust my sleep schedule, I'm sure the app could help see the progress. On a side note, I do not have a nightstand. I use microphone mode with a TV & fan running. The app runs an hour before I sleep and has recorded that accurately.

I have used Sleep Cycle since 2014. I even purchased the app (they have since switched to a monthly service fee and my purchase is no longer honored). Suddenly, about a month ago, Sleep Cycle started freezing when I try to open the app. Re-downloading the app fixes the freezing issue for a few days, then it starts freezing again. I love this app, it's too bad it no longer works.

This is the second time in the past 10 days that I've had to uninstall this app because the alarm refuses to shut off. App crashes when I try to go into the journal to see how long it was actually tracking today since it won't shut the alarm off. I will not be reinstalling it a third time. Also, I paid for the premium content. I want my money back.

Great app. It's nice that I can leave the phone on my night stand instead of my bed; does a good job of tracking deep sleep vs light sleep. PLEASE add an EDIT feature where I can change the time I went to bed or woke up. Sometimes I forget to end the tracking when I get out of bed since I'm still sleepy, and then an hour later I realize it's still tracking. It would be nice to delete that extra time and enter the correct wake time. EDIT: I would also like the option to edit how much sleep I got.

Love hate relationship. I sleep through all traditional alarms. For some reason, the smart alarm in this app wakes me up perfectly! So long as it actually works. I have to keep uninstalling and reinstalling just to get the gradual alarm to function. Which is dangerous because I never know when it's going to fail, and I wake up late. Instead of the gradual alarm softly getting louder until my actual wake-up time, it'll just ring at the time I set; no different than a regular alarm. Upsetting.

So I've used this app daily since 2016, when it was 99 cents. It's typically great, but something with the latest update really screwed up the alarm. it no longer goes off, it will just vibrate twice and go back into snooze mode. I've had the alarm decide to go off 45 minutes after it was set. all the settings have remained the same, there is no wakeup window, volume is up etc...

Great app overall. If it's able to detect noises and movement while you sleep, it should automatically end the sleep tracking once using phone or moving around. That would be an awesome feature. Also, a subscription is hard to justify when most of us have watches that can do the tracking and meditation apps that have sleep stories. Edit: down to one star because there is no "sensitivity" setting. I've been getting woken up as soon as my 30 min window starts even if I'm in deep sleep!

Update: as of about 2 weeks ago my snooze started playing a dripping water sound. It's like being in a cave. I hate it. I can't turn it off though because it doesn't exist in the settings. My wake up sound is "morning mist" but this is entirely different. Looking for new app. I've been using the free version for 3 or more years and love it. I like all the options for alarms and mostly love being able to confirm a good night sleep. or, know why I feel exhausted the next day. great sleep tracker!

I really like this app, but: 1) I often sleep in 2 phases 4-5h at night and 2-3h in the afternoon, and the app doesn't support that - second sleep erases any data from first and statistics show I slept 2 hours for a few days of week. 2) You can't change wake-up time when the alarm rings, there is a snooze button, but if you decide to stay in bed longer you need to turn it off and back on - and have the issue from point 1. It may be a pro for some who have trouble getting up, for me it's a con.

There's not much I like about this app and it is so limited in what it shows you if you prefer not to do a 5-day trial that it's virtually worthless. It also was off compared to my Fitbit. My Fitbit and I have been together a very long time and I know it's accurate and simple things like time asleep are completely different between the two devices. Furthermore it kept saying I was talking in my sleep when it was listening to the included audiobook- audio clip included! Bad!
