Unfortunately, it does seem true that most of sleep monitoring devices are not very good (I'm hopeful for the head-mounted ones, but I don't have any data).

But the advice at the end of your post... I'm trying to put it politely - it's insulting rubbish for anyone with moderate to severe sleep issues.

Correct advice, in the absence of actual REM tracking devices, is to go to the doctor - sleep specialist and possibly also a psychiatrist.

Sorry... it did sound snarky. I actually am familiar with few of the apps and devices and they do just make those recommendations. They throw fancy charts and nice UI at you and then make similar recommendations. I honestly don't think the data collected factors in much. They try and get you to normalize your routine and eliminate distractions and known sleep disruptors. I truly mean that you do not need the devices in order to get that advice. If you have a medical condition then by all means seek medical attention.

A large percentage of the population has sleep issues, suggesting they try the basics is actually very good advice. Much like tech support asking you to restart the device, which verifies it’s plugged in and a host of other issues.

If that’s not working then get a full on sleep study, otherwise save your time and money.
