Do you feel tired? You didn't sleep enough. Do you feel fine? You slept enough. C'mon OP. What's a computer going to tell you that you 3-million year-old endocrine system doesn't already know?

Maybe not a bad first approximation, but this approach would suggest I should be asleep always... Sometimes information can be handy, even if all you're getting is an automated way of collecting information you already had access to.

Sounds like something other than lack of sleep. Maybe dietary or environmental issue. A lot of people who spend time in air conditioned rooms are actually mentally impaired due to high concentrations of CO2 building up in the room. I am not a real doctor, by the way, and this is not medical advice.

Not a user myself. My wife loves her Oura ring. Super comfortable, with the caveat that it doesn't come in ring half-sizes. My college-age kid uses an older FitBit for sleep tracking and is happy with that. I have no insight as to whether the Oura ring is going to give you restless-leg data directly or indirectly, but it is extremely reliable for recording other sleep disturbances in my wife's experience.

I feel like my Oura is pretty accurate. The fact it's a ring makes it very comfortable for sleeping, no issues at all. FWIW, my sleep doctor says Oura rings are not accurate at all, but anecdotally I don't agree with him. I do find the Oura is terrible at tracking activity like exercising, it's just wildly wrong. But for sleep it seems very accurate.

Trying to divine exercise from accelerometer data is hard. My kid's fitbit counted 2 hours of knitting as about 15 thousand steps.

None. Period. I was in human sleep research for 14 years as a technologist and proj manager. I tested dozens and dozens of devices- a mattress pad that claimed to track sleep. None of them are accurate.

to track limb movements you need EMG attached to your legs and then to a recorder. Then a sleep tech certified in scoring must review the results.

A board certified sleep doctor can get you home devices to track periodic limb movement if necessary.

Acti-watches are the only devices that you might be able to get "accurate" sleep(not limbs)tracking. They're expensive and you need to buy analysis software to view results. I would not waste your money on any publicly available device- they wont get you the data you want.

Autosleep for Apple Watch has had a significant impact on my life and I always rave about it to friends. I've been able to recognize choices in my daily life that significantly impact my sleep quality and have made changes that have improved my sleep because of it. I don't know how accurate it is in terms of tracking restless legs unless the movement of your legs causes movement of your upper body that would impact w…

Do you wear your watch when sleeping then now? When do you charge it?

I have a Series 4, and I normally have "Wake Screen on Wrist Raise" turned off except for 30-40 minutes per day when I'm exercising. I'll also sometime turn that on if I'm using a timer that I want to be able to see at a glance.

I charge it in the evening, when I'm relaxing reading or watching TV. I can usually get it to 100% before I go to bed. If not, I'll put it on the first time I wake up to urinate that night.

By the time it gets to the next evening, it is usually at 55-65%.

If I forget to charge it in the evening (e.g, I fall asleep while reading or watching TV), it would probably make it fine to the next evening. In those cases, though, I'll stick it on the charger while I shower and have breakfast. That's more than enough to ensure no problem getting to the evening.

https://ouraring.com/ is pretty awesome. I've started sleeping more, at more consistent times, and consuming less caffeine and alcohol. $75 off - http://ouraring.com/partners/rohannatraj - doesn't benefit me, just a coupon I received myself.

Bought it few months ago, mostly due to being impressed by the engineering side of it, then had a closer look at the data it was collecting at night and it looked very much like something pulled out of someone's ass. It literally did NOT correlate to what's been happening. It showed "deep sleep" for times that I was awake and was checking my watch, it also showed REM sleep when it was clearly a deep phase, etc. First…

I've been using the ring for a couple of months now and never these issues. Whenever I was awake (even when I didn't move), the ring correctly recorded it. When I wake up even for just a second to roll around and faintly remember it, the ring correctly tracked it.

Not saying it's the most accurate thing because it likely isn't, but it's still far better than other trackers IMO

Thanks for the discount, don't know if I ever had a coupon that forces me to make a decision in 30 minutes! Smart way to make a sale, give me just enough time to do a little research knowing the clock is ticking... I was about to close the tab but then I saw they have developer tools where you can get an API key to access your own data -- very cool

I assume this is sarcasm?
