I am using smartwatch, I know it's not the bast way to track it, but I am not having sleep problems so it works for me

smartwatch for me

I am using a Garmin- tracks Rem, light sleep, etc. and then gives you a sleep score. Idk how accurate the score is but alot of friends love it.

Personally I use a Garmin Forerunner 235. The whole forerunner series would work pretty well, especially the cheaper ones if you just want resting hr and some basic sleep tracking. I like it since I use a Garmin edge 530 head unit so activities/stats from both sync to one account. The watch is great for tracking hikes, commutes, strength workouts etc... When I don't have my head unit.

My favorite part of the Garmin ecosystem for this is body battery, which is almost like recovery score but it is updated throughout the day based on rest/stress your watch detects. For example, it recharges while I sleep, depletes as I go about normal activities/exercise/deal with stress, and recharges if I nap or otherwise rest throughout the day. It takes a few weeks to learn your rhythms, but after that I've found it to be a really good proxy for how I feel, a lot more useful than just resting HR. It's not perfect, but if I had to choose one number to track my metrics it would be that. The sleep tracking is mostly okay, although it gets a little weird sometimes.

I wore analog watches before buying this and in the the three years since I've liked the Garmin watch so much that I'll probably never go back to analog watches.

Oura ring.

otherwise, get a Coros Pace 2 and wear at night only.

I absolutely love my Garmin 955 solar. I tried Whoop (horrible experience and a stupid subscription,) Apple Watch (tech isn’t there yet for athletes,) and now Garmin universe! The body battery feels accurate, and it’s nice to track HRV and resting heart rate.

I like my Garmin Forerunner 945 for tons of things but Garmin is notoriously bad at like properly tracking sleep so I just rely on a phone app for that and keep my phone on my bed while I sleep.

I do like the body battery feature which is an HRV monitoring thing. It's nice to look at and generally correlates to how I feel but I would never base anything on it. Same goes for any HRV monitoring device, though - none of them are actually accurate enough unless you're using a Polar H10 HRM strap and checking every morning at the same time.

The RHR measurement is also nice, though again it's from an optical wrist sensor which is far from wholly accurate. I trust the RHR pretty well, though I don't trust the sensor at all during activity.

I think Garmin's watches are among the best out there - just realize that anything you're getting from a watch should be taken with a pinch of salt and won't be completely accurate.

I scored a whole blood pressure, pulse, EKG, and oxygen meter machine from a medical supply company. Straight from an ICU that got torn down. I hook up the wires, point a video recorder onto the machine, and I go to sleep. Next day I can watch the footage and see how the numbers look. I also use this method to ensure I’m getting the appropriate amount of nocturnal erections since the “supplements” (wink wink) I use for cycling has a few unpleasant side effects.

Brown skinned here, which may affect OHR. It’s perfectly adequate at rest, when exercising it’s often very very wrong, I got a HR strap for when I’m actually moving. Otherwise love the Garmin. Bought mine used for ~130, Forerunner 935.

I use Sleep Cycle apps with my Apple Watch. Works great for me.

My Fitbit Luxe was less bad than my Garmin Vivosmart 5 for rotating sleep. Had/have to correct its start/end times a fair bit regardless of timing, but that my be more ME/CFS. Graphs the staircase ok.

Tried the Oura, didn't like it

You could have a look at the reviews from The Quantified Scientist on YouTube - he compares his results from wearables with professional sleep tracking devices.

From what I've seen, Apple, Pixel, FitBit, Whoop and Oura are the most accurate, but still, it's a one person 'experiment' so other people have had ok results even from devices that didn't have the greatest accuracy for him.

You should also think about what kind of metrics you're trying to track. Just the sleep onset/offset and a sleep score? Temperature? HRV? Snoring and/or sleep apnea? Do you also want to use it for other purposes - certain apps, exercise tracking? And generally the specs of the device like battery life.

these prob arent as accurate, but there are sleep apps where you put an iphone on the mattress to track

Anything that tracks heart rate gives me anxiety and disrupts my sleep

Have you tried a different band for your watch? I use a soft nylon one for my Garmin at night and it doesn't bother me.

You can put the apple watch on your leg wrist

Eight sleep has sleep tracking built into the mattress cover but it’s not very good.

I use my Fitbit wristwatch, have for quite some years.

But I don't look at it too closely, it's more hours slept, quality I can gauge myself in the morning anyway.

If hours slept starts to drop over a set period I start to up my dose of quetiapine, normally it's ~25mg but I'm free to up that to 100 if I want to.

Too little sleep is a very clear indication of hypomania for me, so keeping a lid on that helps tremendously.

I do! I just use my Apple Watch

Bro I’ve tried every tracking stuff app and I can’t even remember to input my progress XD

What sleep? 😭

I track myself manually using daylio for sleep hygiene - did I go to bed on time, wake up on time, did I have anything to drink, what was my sleep quality, etc. For sleep logging itself I use Fitbit on my pixel watch.

Oura Ring has been super accurate for sleep tracking for me. However it is not the most affordable option. You could look for used rings, people do resell them for cheaper.

8 really like my FitBit Inspire 3. The sleep seems accurate, especially comparing yourself to yourself on different days, it's pretty cheap and small. I use it for all my daily things for like a year and a half now, and still super happy. No monthly payments required either

I like my Whoop for sleep tracking but it’s not cheap. I find it’s more accurate than my Garmin and correlates better with how I feel

I have an Apple Watch and an Oura. I recommend the Oura for sleep. Here's why: the device you use need to be charged up and ready to go when you go to sleep. The apple watch has about 1 day of charge capacity and the oura has about 6. Meaning if you wore the apple watch during the day or forgot to charge it up, it wont be available to track your sleep that night. The oura can sit on its little charger at your bedside and you just slip it on when you get in bed. Easy peasy. Always ready to go. No mental overhead about attention to charging. I also find it more comfortable to wear the ring to sleep than a watch, personally.

I like the Apple Watch through AutoSleep honestly. Mostly use that plus Eight Sleep (the latter is the more reliable for time slept).

I’m really enjoying the Oura ring, I own the Apple Watch Ultra also and it’s great but I hate wearing a watch to sleep but with the ring you can’t even tell it’s there.

8sleep has the best sleep tracking but is very expensive and cannot track exercise or during the day.

Apple Watch has second best sleep tracking, almost the same as 8sleep, and doesn’t require a subscription. However, it presents the information poorly, has a lower battery life than whoop and oura and maybe be uncomfortable to sleep with for some.

Oura 3 with the latest update does quite well for sleep tracking and slightly better than Whoop. It also has a much lower subscription fee and the best battery life and form factor. However, it has a steeper initial price and requires you to buy new equipment if you want to always have the latest and greatest.

Whoop did better than oura for sleep tracking until recently. However with the new update, oura rings wins by slightly but not much. Whoop has no upfront cost, but a higher monthly subscription. The subscription includes being provided with the latest and greatest new equipment without paying for it. It also can track sports and fitness the best.

I use the watch ultra. It has two to three days of battery life.

If you are just looking for metrics and no smart watch features like time, notifications, google assistant, etc. Check out the whoop strap. I have been watching a lot of videos on it recently and most of the athletes testing it say it has really amazing accuracy. I havent tried it myself but I am thinking of trying it because it is getting such rave remarks about sleep tracking specifically.

edit: for reference one guy mentioned in his video that the fitbit checks our heartrate about once every five minutes unless you manually switch yourself onto "workout mode" which brings it up to once a minute. The whoop strap analyzes something like 100 times a minute always. It also has extra sensors that the fitbit doesnt have.

All-day heart tracking, be careful with android watches because most (if not all) of them that claim "24/7" heart rate tracking are really only checking a few times an hour, mainly for battery considerations. Ticwatch does this; maybe 3-4 checks per hour. Contrast with samsung and fitbit watches that do "continuous" heart rate tracking.

For sleep tracking, check out this guy's youtube channel below--he's studying sleep science and data science, and does comparisons between wearable devices and sleep study devices: https://www.youtube.com/channel/UChNWxrTlmh4IRSevon1X93g

Personally, between using fitbit, android wear/wearOS, and samsung watches, I've found fitbit is the most consistent and accurate with sleep. Samsung is the least (mine never registers any real deep sleep, I think there is flaw in their measurement because this has happened in the active and active 2). I wore my fitbit while I did a sleep study, and it was in pretty good agreement with the sleep measurement devices.

If you want accurate sleep tracking Fitbit would be the way to go plus you would get much much better battery life. I tried the to watch pro 3 GPS for a little while and the sleep tracking always really hit or miss. One time I was at a movie and it recorded it as if I were sleeping. If you want battery life Garmin is a good option. I have the Garmin Venu and get usually about 4 days of battery life. But I will say Garmin makes actcivity/fitness trackers with some smartwatch capabilites they have alot of options in terms of devices and if you are a data junke Garmin is truly the way to go

Sleep tracking - other than duration its all a very bad guess. Can't properly determine sleep stages without tracking brain waves.

So as long as it automatically starts tracking when you sleep and when you stop to give you duration - you are good to go.

For the rest you are probably better off with a Garmin and or a Fitbit as both seem to go into estimating health off things like respiration rate. Not sure how really valid all of this is, but they think they can tell you.

This is a great channel for super accurate sleep tracking analysis. Fitbit is leading according to his tests.

Anecdotally, I am super impressed with my Fitbit Charge 4. It is very accurate when it comes to my sleep times and times I wake up. From what I can tell, it is also accurate when it comes to my deep sleep and REM stages. I haven’t tried any other product, though. There are quite a few studies and reviews online, I think some that are credibly scientific.

check out quantified scientist on youtube. from his tests it seems like as far as wearables fitbit is the most accurate

My cat always knows when I'm asleep.

I love my ōura ring.

I use my Garmin watch, the 7 series, but the Tactix model.

It gives excellent reading of all my sleep cycles and seems very accurate. It also has a body battery tracking program that is scary accurate. I base every single day of my life off that battery level.
