I'm sincerely enjoying the ability to track my sleep and the activities that affect it. It's intuitive that exercise helps you sleep better buts it's impactful to see it proven in the app.

I don't know how they are obtaining all of the data but it's working for me. I have used it 2 nights in a row and have woken up feeling fine. I have had 2 great days in a row which is rare for me, keep up the good work.

I love Zen Labs apps. They are easy to use and do what they say they will do. I want to get the right amount of sleep for me. It's amazing it wakes me up at the time my body is ready to wake up. I like seeing the analysis to see how much deep sleep I got. Helping me with my health goals. Keep up the great job!

Zen Labs has produced far more than "just" an alarm clock. This application tracks your sleep, dream patterns, etc. Very helpful tool.

Being able to see my sleep pattern depending on the activity I did is really helpful. For me personally, working out before going to bed seems to really improve my sleep, so now I try to dedicate some time to make sure I get in some exercise. Win win situation for me!

Very disappointed in this app. I have used it two mornings in a row and both times it has failed to go off - good thing I woke up on my own and didn't sleep through any meetings at work. The first night I used it, it also said I was awake the entire night, possibly because I had a white noise app on at the same time. I can't believe I paid $4 for this; I've asked for my money back and we'll see if they agree. Obviously I'm better off using the sun as an alarm clock than this app. Don't waste your money.
