Sleepzy - Sleep Cycle Tracker

It worked great up until recently. Before I say the problems, I do really like the sleep debt tracker and the alarm. The added noise for falling asleep is pretty great too, I like it. The downsides are it performs horribly, when I start the app I have to wait 2-3 minutes before I can even start tracking because it is completely frozen. This is on a new iPhone 11 Pro Max. I have reinstalled it and all that jazz and I’ve just accepted the fact that it is optimized like garbage. I don’t know if you could call it a problem but the second thing that bothered me is the mic can recognize things that aren’t you as you. I couldn’t figure out why but for a couple weeks it kept saying my sleep quality was less than 20% and that I didn’t sleep all night racking up sleep debt as high as 40 hours in one week. I fell asleep one night with my fan off and it went back to normal, turns out the app thought my fan was me snoring or rolling around and throwing the data way off. Overall good app but it can be inconvenient to use sometimes.

This app is great. You set a time to wake up and it will wake you up sometime up to 30 minutes before your set time to try and use what it collects through the night and what we already know about the human sleep cycle to wake you up at the perfect timing for where you are in your current cycle. The issues with this app is sometimes I feel as though the app doesn’t know when to really wake you up because it doesn’t get enough information accurately about your sleep. But in its favor it’s noninvasive (you don’t need it in bed with you) The bugs are just annoying more then a hindrance. Sometimes it’s only buggy when your trying to do something that would be weird like setting your alarm to activate the application for the night while on the phone talking to someone still crashes the app. If you are in the app while on the phone and try to start the alarm for the night after getting off the phone the app will either crash, freeze, or just not respond to the start button. You have to restart it and usually it will work. I get ads even though I’m premium. But rarely and seem to be short ads. When you get a phone call while the alarm is activated if you don’t play or even just have the background noise paused it’ll start playing it when when the call stops. Hopefully the developers can squash these bugs since they been around for a little bit. Happy sleeping sleepzyers!

I really love this app. I saw some other reviews saying it has a lot of ads or that it thinks as soon as they set the phone down they're asleep... I haven't had that problem at ALL. I don't think I've seen any ads (or so little that I forgot them) and it shows I'm awake for a while before I actually fall asleep. That could just be because I move a LOT when going to sleep; but either way it's perfect for me. It's also really interesting to see the sleep analysis, I don't know how accurate it is but it seems to be pretty true... and it's really cool to see. And it reminds you how much sleep debt you need to catch up on which is ALSO cool, plus the wake up within a half hour of when you need to be up is nice, as it can pick when you are in the lightest sleep and ready to be woken up. My only issue is that I have to remember to unplug my headphones or else it'll just play in them (I usually listen to music before bed, and often I fall asleep and they fall out of my ears) but thats a small price to pay for a great alarm clock!
