Most improved


Sleep watch has improved to the place I want it to be. I get all the information I wanted that I got from other non Apple apps in here. The one feature lacking that they fixed was estimation of actual time slept. A while back, about 6 months ago, their app couldn't accurately track my sleep time. If I woke up at 6:00 am then went to bed at 6:30 to 8:00 again, the app missed it. TODAY it captures that to give a very accurate assessment of ALL my sleep. Yeaaa!

Also they are updating and adding more features that I didn't have in the non Apple apps.

Hats off to Sleep Watch! Today it is a great app and I recommend it if you want to improve your sleep habits or just find out how really crappy your sleep really is.

Night shift


Great app! Still trying out the “experimental” feature of the all day sleep detection. I work 12 hour night shifts 3 times per week as a nurse, so you could say my sleep patterns are irregular. I was off all weekend so I slept at night and the app worked beautifully. However, today as I slept in preparation for my shift tonight it did not detect that I was asleep at all. Since it is an experimental feature, I’m going to give it a few more chances or maybe increase the sensitivity of sleep detection. I hate to make the comparison but I did recently switch from Fitbit to Apple Watch and there was never an issue with sleep detection no matter when I slept with Fitbit. Hopefully strides are being made for those of us who enjoy tracking our sleep! Again, a successful app.

Great performance


Sleep Watch is the easiest, most accurate sleep tracking app I’ve used. The way it charts restfulness vs restlessness alongside my sleeping heart rate has taught me so much about my own sleep patterns. I tend to sleep at all weird hours… napping during the day and not going to bed until well after 1 AM. Sleep Watch accurately & automatically detects all my sleep – even 20 minute naps in the middle of the afternoon. This app has identified how irregular my sleeping patterns are and now I’m working to change that. I feel better, I’m less like Shrek in the morning and I have become more aware of how important a good night’s sleep really is. Sleep Watch is one of the few apps that I truly can say is life-changing.
