Anecdata: Have sleep apnea, so am interested in better sleep, and I'm hooked up to a CPAP machine which registers every breath I take. I've tried several devices (withings, 2 garmin smart watches and a fitbit), and quite frankly, the results have been appalling. Some random observations: * My latest garmin has an "SpO2" sensor. Which is basically a random number generator with red LED. When I compare the results with…

This reminds me, I was suprised to learn that ECGs can measure breathing (well, not the least expensive ones but most). If breathing is enough then an ECG might be one of the better ways for anyone who doesn't need CPAP and there are some available with local analysis software. They do require a prescripition in many places.

Can anyone recommend a good sleep tracker with a smart alarm?

I had one of the original Jawbone Ups, and it was great for this. Sadly, it didn't last forever and now they're discontinued. I did a solid search about a year ago and couldn't find anything that suited - essentially a sleep tracker with a smart alarm that's not tied to a mobile phone, and ideally with the ability to wake via light as well as noise.

(I get that the Apple Watch offers options, but it never seemed sensible to use a) use quite a bulky watch to sleep with, and b) choose a watch that would ideally charge overnight, to capture sleep data.)

I haven't seen Withings Sleep mentioned - https://www.withings.com/us/en/sleep . This one is basically "set it and forget it". You put it under your mattress and calibrate it, then it tracks automatically. I like it because I don't have to bring any gadgets into the bedroom, or remember to turn on tracking. It seems pretty accurate from what I've seen so far, although I don't have anything to compare it to. I've foun…

I've been using one for me and my SO and it's been working pretty well for us. Can definitely confirm that it shows marked improvement in sleep once I got a cpap

They are all garbage, without monitoring brainwaves you have essentially zero useful information about sleep quality/duration/stages. No amount of accelerometer/heart rate data is going to accurately reflect your sleep stages, regardless of what marketing spiel you read.

For a brief time there was a consumer product "Zeo sleep monitor" which was a legitimate EEG-style brainwave headband you would wear to sleep. From what I recall, comparing it's results to those of in-lab sleep studies, it was fairly accurate.

Sadly they went out of business as it was a fairly niche product and pretty expensive.

Autosleep app on the Apple Watch is perfect for me. Completely automatic and accurate to ~5 mins plus info on deep sleep and heart rate. It only requires the presence of mind to charge your watch another time rather than overnight.

Hmm. My Fitbit (Alta HR) considers masturbation exercise.

Though, it has recorded that I was in deep sleep while I was awake.

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…

Seconded, Autosleep works fantastically well

Sleep As Android I don't think it will directly track leg movement, but it tracks sounds, so if you're shuffling the sheets it could possibly pick that up. It's a very highly rated app and I've used it successfully myself.

These types of apps are great in my experience... unless you use a white noise maker or a fan.
