Most accurate of the five I've tried

I've used FitBit and Garmin and those have good built-in sleep trackers. I was disappointed after getting my Apple Watch that it doesn't have a built-in tracker, I reckon so they can make more money on app sales. Anyway, I tracked five different sleep tracking apps assiduously for three months and I can confidently say REM is in the top two (the other you could call SW).

I give REM the top score for accuracy, the other app the top score for additional factor tracking such as HRV, blood O2, and respiration rate. REM is my top pick if you want a simple and accurate sleep tracker. It would be hard to beat and worth a sub if they added a couple more factors that the watch can track and provide to the app.

I didn’t originally love this app.

Unsolicited review. I bought this after reading several reviews about it. Wasnt crazy about paying for a sleep app when there were free one’s available (including apple’s health app). Most of the apps I used prior to this either were really not accurate or provided a million details I didn’t care about. When I downloaded this for a trial, it didn’t seem to track my sleep accurately. I provided feedback to the developer and it has become very good. It provides exactly the level of detail I want, and is very accurate now. Definitely worth the few bucks a month in my book if you want to track your sleep patterns. Ive always struggled with sleep regularity so I love it now.

Most accurate sleep tracker I've found

I've tested several sleep trackers now and this one has been the most accurate. I love that I don’t have to explicitly tell it every night that I’m going to bed, it figures it out, and it doesn’t record false positives during the day.

It also does a good job of accurately reporting data to the Health app. A few of the previous trackers I used really messed up my sleep data.

My only gripe is I wish there was a way to schedule daily smart alarms. Currently, I have to go in and set the alarm every night, which kind of ruins the whole “automatic” aspect of this.
