Keeping on bed is inaccurate. My partner moves and it detects it. Maybe if linked with Android wear watches could be great app with more accuracy 3/5

I've used it for a while until I got my fitbit... and since its function overlaps with the fitbit sleep tracker, I stopped using it as much. It would be amazing if it syncs with the fitbit though. 4/5

I wish the smart alarm had a "before and after" option, where you can tell how much longerAFTER the set time you want it to keep tracking, because if, by an unknown reason, you don't get to light sleep within the 30 minutes, it wakes you up mid-REM anyways. It's not a problem when I do the setting up, since I can set it to 15 minutes later than the right time, but it is an issue with auto-alarm, and snooze can't help you go back to REM, so you spend the say exhausted as you did with your cell phone alarm. 4/5

This app is really good. I like knowing how long I've been sleeping for and also writing my dreams in the note field. I have a few suggestions though; auto-capitalization on the note field would be good. Also perhaps allow the punch-in offset to be entered rather than selected; big difference between 15 and 30 minutes. I also found this morning my log wasn't showing and I had to close and reopen the app a few times. I was worried I'd loose all my entries! 4/5

Really cool app. If you want to learn about your REM sleep cycle, I highly suggest this app. Was really amazed at what I found out. Won't ruin it for you, get it and you will know what I'm talking about! 5/5

After my first child was born everyone (including myself) kept wondering how much sleep I was getting. I was waaaaay to tired to do the math after waking up 4 times in the night. (or even remember when I was awake or asleep). This app filled the gap wonderfully. I don't use the alarms at all, but the sleep tracking is exactly what I needed. 5/5

This is really good! Helped me a lot. Now I'm more aware when I need to rest and sleep. I will give it 5 stars if you can make it not reset the alarm for another 8 hours when I wake up and go back yo sleep again after several minutes. Other than that this is really good. 4/5

Firstly, this app has many great tips and trick to help you stay awake or fall to sleep but.. The smart alarm for me anyway (Samsung Galaxy S4) seems to have quite bad timing, it acts like a regular alarm clock waking me up at the start of its 30 min period, instead of evaluating current trends. 4/5

It came up in the search engine for Zeo, I've been looking for a more stable alternative to the discontinued MyZeo app for adaptive alarms but this doesn't seem to be able to connect to the headset. 3/5

I like it, but I wish you could pick which alarm was the smart alarm because I have to take medicine two hours before I actually get up and the smart alarm only works for the earliest alarm so I used my phones alarm to take my medicine, but it messes with my phone's alarm by not allowing me to turn the alarm off. I wish this could be fixed. Other than that I love this app. It really has helped me with sleeping. I just wish that one issue could be fixed. Please? 3/5

I've only used the sleep log option, so I have no idea how well the other options work. I do wish there were an easier way to log sleep disturbances (i.e. kids coming in at 5 am to ask for water...) I'm a stickler for logging every thing, and the fact that the auto alarm resets every time I wake up for 5 minutes is kind of annoying. 4/5

I like almost everything about this app. Usually it does wake me up during a lighter stage of sleep, but sometimes it wakes me up in the middle of a dream (guess I'm moving and it's misinterpreting the movement). I tried Sleep Tracker a while back and returned it, partially because the bulky watch sucked to wear. I like not having to wear anything on my wrist to use this. Something I would change is the giant Snooze button that I often hit by accident. It should have a slider instead. 4/5

I've been using this app for years and am experiencing bugs. I CANNOT answer calls that come in before my alarm goes off. NOT GOOD. The alarm ALWAYS repeats. I have it set not to, but it will go off again if I don't go in and manually uncheck it. Luckily I remember to do so or I would be in a lot of unwanted situations out and about. 2/5

I am finally able to setup the app to be useful to me. It has many options - some of which are not related and are too detailed for the average Joe. The sync process could improve. Also, it seems like the daylight savings time is not calculated correctly for the Offset hours. 4/5

I have been using this app for nearly a year now and it is hands down the best alarm clock, sleep analyzer, and dream journal out there. Not to mention that all your data is synchronized and backed up online! Would definitely recommend. 5/5

I've had this app for over a year but all of a sudden it's started making up its own time to wake me up, like at 4 o clock this morning despite the fact I set it for 7 with a 15 min leeway. WTF! When I set 1 alarm, don't expect the app to erroneously set an extra 3 at it's leisure and at rediculace times of the morning. 2/5

I would have to actually unlock my phone before it would allow me to dismiss the alarm, and even then it wouldn't always work. I pretty much would have to turn off the phone. And the smart alarm didn't seem to work. Good idea, but it has an lot of bugs. 2/5

The graphs are not log scaled so you don't see much of your sleep activity, indeed the light sleep shows as spukes on a flat deep sleep for me. Even after waking up on the light sleep alarm, it goes off again at the alarm time for me. You don't get to select your alarm. I guess you get what you paid for with this product but at least it works sort've, well not really for me. 3/5

I tried to set my alarm for a given time, but the app refused to set an alarm any earlier than eight hours from the current time. These are tools for us, not the other way around. Uninstall. 1/5

My phone memory got full even though I removed every music image or film to my computer. Then I found that if you choose to record sound it is not just checking if you are making noise. I actually saves all sounds you make. I tried to erase them one by one but I could not. When I erased the whole directory I freed 900 mb. Fix that please 2/5
