1. 5/5Thank you, best sleep tracker

   I am suffering with sleep issues and wanted to try apps that tracked sleep, I used for a few nights and got no deep sleep rating, so I did a blind test and got my wife to wear it, so same watch, same bed different person. I wanted to see if it really saw deep sleep. It does it tracked her and saw the deep, rest etc. On the bad side shows had bad my sleep is, but I know the data is true as we both show completely different sleep patterns. Then I emailed support, it turns out I can fiddle with the settings. Once I lowered the sensitivity, my sleep data is showing up correctly. I am happy, just wish the instruction is easier to find, but otherwise it is a great app.

2. 1/5No stars

   I downloaded this app in anticipation of getting my watch so it would be ready to go when it came in. I have the 3. Set up the watch as per direction, paired it with my phone and all my apps were there including this one. Set up the app everything looked good. Wore my watch to bed and had a horrible night of sleep. I’m not sleeping well and wanted to see how much rest I’m actually getting. Woke up and checked the app on my watch. No data. Checked my phone. No data. Synced my watch to my phone again. No data. Ok maybe I did something wrong. Uninstalled the app and reinstalled it. Second night I had the app open in my phone and on the watch (as much as you can leave an app on). Wore my watch to bed. Slept better so I thought for sure it would have something. Still no data. Phone- no data. I have now uninstalled it and purchased AutoSleep app. Don’t waist your money.

3. 4/5Has a bug :-(

   My best friend and I both loaded this application over a girls weekend...the information from the first nights sleep was amazing...love the layout and the heart rates etc. The second night both of our watches were dinging almost hourly telling us to either stand up or breathe...ALL NIGHT LONG ! I have called Applecare and they state that it is s third party app causing the issue...and suggested either turning off the reminders for stand and breathe before going to sleep and turning the reminders back on each morning or NOT wearing the watch to sleep...that’s a work around I’m not willing to do :-( As soon as the developer fixes this problem I will reload the app.

4. 4/5I think this will work out in the long run.

   I just download this app yesterday morning (5/28) and have went through all the settings. I took a 2+ hour nap and timed it. It was off by so I adjusted the sensitivity. Went to bed last night and it was only off by about 8 minutes (going to sleep) and I adjusted my middle of the night bathroom break time this morning in the other portion of settings. Over all, once I find my perfect combo of tweaking, this one is going to be the best sleep app for me of all of them I’ve tried (and paid for 🤢) You have to be patient and perfect your settings for the best possible accuracy. The other thing I’d like to see is a combined hour and time of hours/minutes slept a night IF one has gotten up in the middle of the night instead of it being broken up. That’d make it a 5 star app for me.

5. 5/5This one works

   I don't know what the negative reviews are about, but they inspired me to write my own. I've tried a lot of sleep apps, and this one actually works like (or better than) my old Fitbit. There's no way to know the real accuracy, but after I adjusted the sensitivity, it matches my recollections of my sleep, including how long I was awake reading, better than any of the other apps I've tried. As for other apps: AutoSleep is just inaccurate unless I tell it when I'm going to sleep, and it says you need to have the complication on your nighttime watch face, which is basically the same thing. Pillow wants me to tell it when I'm going to bed too, and then refuses to work unless my battery is like 60%. Since I charge it in the morning when I'm getting dressed etc, that doesn't work for me. This one, SleepMatic, works great.
