1. 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.

2. 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.

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. 5/5Quite fun after accurately set up.

   This is definitely worth the investment. I’ve recommended it to my family. Helps me track apnea episodes n compare to my weight n exercise+meditation regimen. My doc likes reviewing my results when I go in. I’ve found that I have fewer apnea episodes when i weigh less n exercise/meditate more. Duh, i should’ve known this. Need more time with my swordsmanship. As Miyamoto Musashi said of the sword ... This Is The Way. Especially at 53. I wonder what it will be like with series 7 or 8 watch assuming spO2 measurement improvements. I highly recommend this over the others in the market. I rank this number one in the top 5 in App store! Pillow n others were a waste of money.

5. 2/5Not very accurate for me

   I started looking at the clock when I wake up during the night so I could compare data with the sleep app. It does not count my wake episodes. I adjusted the sensitivity and it hasn’t improved. My fall sleep and wake up time isn’t correct either. I also do not like that I have to have WiFi on for the app to record my pattern. I sleep with my wrist by my head and do not want the WiFi signal near my brain. I had a free app that worked without WiFi on. It sent the data to my phone after I turned it back on. I just didn’t want the advertisements that came with the free app. I might have to switch back and deal with them because it recorded my info more accurately. Sorry, I really don’t like to post negative reviews. Funny it won’t allow me to post unless I have more stars. I only wanted to give 2 but it keeps saying my nicknames are all taken.
