Hi Julie, Did you decide on one and if so how do you like it?

I'm considering getting the Dreem 2 on sale for $299, but I'm struggling to find time to research it well (as with everything else ;) ). Also the Dreem app just has average reviews. One would think if their device is so much better than others they would be putting time, money and energy into a highly rated app experience. No update in seven months despite the complaints, so not sure what to think about that. Optimistically, maybe they're working on a major overhaul?

A while back I read the FDA registered isn't the same as FDA approved, but I'm not clear on the difference.

Thank you for letting us know. That's a huge sale, down from $499!!! I'm going to order today. My research suggests that this is by far the most accurate sleep tracker out there as it uses actual EEG measurements vs. proxy biomarkers. The Oura Ring appears to be the next best thing. A Google search reveals various reviews comparing the two.

Thanks for that feedback. I'm conflicted about ordering it, only because of any cost for anything these days, and because I desire to go more low tech in life in general. I don't like what being hyperfocused on data does to me. I'd like to know what Dreem 2 'thinks' about my sleep, but have a feeling once I get the pattern I wouldn't use it, so in the long run it's still expensive unless I wear it long into the future. Please let us know, if you think of it and have a chance, how it works for you.

I've used the Dreem2 for over 300 hours along with the Oura ring that I've had for about 2 years. There's no doubt that the Dreem2 is more accurate as it measures your brain waves. Here's a good YouTube video documenting that:

https://www.youtube.com/watch?v=OIokaYy5dXk

The 2 trackers are pretty aligned on time in bed, awakenings and heart rate. But not on sleep onset or sleep stages. They are not congruent there. I trust the Dreem 2 on that. I like the Oura ring with respect to HRV which I understand is pretty accurate. I think that is very important. However, I stopped using the Dreem2 after about a month as the information was getting repetitive and not actionable. I only use it if I make a notable change in my sleep protocol. For example, recently I stopped using my CPAP machine as I lost 20 pounds and wondered if I still needed it and how that would affect my sleep. Well to my surprise both devices (I used Dreem2 for a week) indicated significantly more deep sleep. I was very surprised needless to say. The Oura ring is obviously easier to use (more sticky as Matt Walker put it on a recent podcast with Peter Attia), but the algorithm used for sleep stages needs improvement. If you want accuracy and can afford it, I would recommend Dreem2.

Thanks Jim. Great feedback. I'm still hemming and hawing over the cost, even on sale.

If it makes you feel better, Circ, my Dreem2 is still sitting in the box. I've been too busy to play with it, but plan to bust it open tonight. I think part of me is afraid of what I'll learn, lol. I've also recently discovered this continuous pulse oximetry gadget, for only $179. I think I'm gonna bite.

Interesting. Thanks for the link. Please let us know what you think about it. I need an upgrade from the inaccurate $30 Pulse Oximeter I bought, since bad information is worse than no information.

the continuous pulse oximeter in your link is quite a good little gadget, I believe, but we didn't get the ring model. Instead we got the Sleep-U, made by the same manufacturer, Viatomtech, which is a wrist band unit with an attached sensor that goes on your thumb. We got one to monitor how well Marion's CPAP is doing for her, and we've both tried it. It is, of course, bluetooth enabled, and I can see the report every morning on my iPhone. It works marvelously well. Out of curiosity, why did you want a non-bluetooth, Julie G?

For me, I don't sleep around radio enabled devices.

'kay, thanks... i suspect that's the case with many folks. I don't know if it would make any difference to those who feel similarly, but the Sleep U only transmits data after it's "turned off", that is, after it is no longer actively reading (removed from the wrist and finger/thumb).
