Not sure about accuracy but heck what do you get for free? Know the time awake is not usually recorded. Would like to make more sense of the pie chart in stats. Have that explained. Good for a free sleep monitor.

I love this app, but with the last update I shuts down overnight. Three nights of no morning alarm or recording if my sleep pattern m.

Great!

The app seems to sense movement fairly accurately and like similar apps allows you to add your own daily notes. The only thing I would love to see added, as someone with hypersomnia, would be the ability to record more than one sleep event each day and designate whether a sleep period is a nap or main sleeping period so that stats can be gathered for both types. Otherwise short daytime naps end up messing with the stats for the main overnight sleep period.

It is so helpful to be able to keep track of my sleep quality and hours, and I love the alarm!! The spare snooze backup feature is especially helpful, if I accidentally go back to sleep!!

Seems pretty accurate. Detailed historical graphs. I like the calming wake up alarms available. Could do with some more information about what it all means, to save having to look it up elsewhere.

The alarm is like being gently woken by a delicate sunrise, but the sunrise is made of pillows. The charts are pretty sweet too.

Great insight

A great monitoring app. I can see that other reviews can tell you how great it is, but I'd just like to share how I love the way the app gradually wakes me up without the usual jolt of regular alarms. I feel much healthier when I wake when I need to and feel I've woken naturally.

I've used this app for a couple years and it has been great. I switch to airplane mode and have it under my pillow while I sleep. Recently it has been draining my battery when I use it. I will wake up and find my phone died hours before. Please fix this app. (iOS 10.2.1 iPhone 5C).
