Benefits of using a sleep tracker and sleep cycle alarm clock
With modern day work schedules, our sleep patterns have become widely irregular and oftentimes much shorter than they should be. PrimeNap Sleep Tracker can help you analyze your sleeping patterns and correct them if necessary. Using PrimeNap's smart alarm functionality, you can avoid being pulled out of deep sleep by a well-meaning time-based alarm clock, and instead wake up gently after sleep cycle completion and thereby simulate a natural awakening.
How it works: Movement during sleep is known to roughly correlate with the actual sleep stages obtained by polysomniography. This sleep movement is registered by the phone and translated into fairly accurate sleep cycle information.
Recommended use: Use this sleep app with proper hardware. If convenient, switch on airplane/flight mode to minimize any emissions. Reboot or close other apps that might cause the phone to heat up during the night.

It worked perfectly for a week and the last 2 nights not at all. Last night said I had 12 minutes of REM sleep and over 8 hours of light sleep and no deep sleep. And I was really sleeping all night. So don't download this app whoever created it didn't study sleep patterns at all. Back to the Play store again. Love what it offers though Deep and REM sleep.

It has exactly what I was looking for And more which I like, however the graphs are a bit confusing with 2 sets of times. Ease of use could be better but over all its a good app!

Had varying degrees of success with it, thought initially was great untill I had a night of no sleep and it measured a having deep levels of sleep, I guess if I'm not tossing and turning though, its going to record as a good night's sleep. Last night was different and I believe it got it spot on, i remember a lot of lucid dreaming, waking up briefly and going immediately back to dreaming. It measured only 10% of deep sleep and around 45% of rem and light sleep which seems consistent with my nights sleep.

I like how it shows how long you've been in a light or deep sleep. It really helps when I tell people I'm a heavy sleeper and I didn't get the message

It gives you the general idea of your sleep patterns. Wish the sleep sounds would last a little longer, sometimes they turn off before I've fallen asleep.

I use this app solely for the Night Mode feature, in conjunction with the app "SleepBetter" for the alarm and for tracking sleep. I really enjoy the night mode on here. It's customizable, so it's not just one color. You can dim it VERY dark which I love because I am very sensitive to bright lights. And the red filter does a great job at blocking blue lights and creating a more calming screen when used with dimming. And there is a button within your notification bar so in the morning you can simply click and the night mode is off. I have not tried the other aspects of the app, but if you're looking for a good night mode or red filter app, I would use this. I have downloaded others before that gave me ads and notification advertisements on my phone too.
