Best Sleep Trackers EXPOSED: What Actually Works!

Best Sleep Trackers EXPOSED: What Actually Works!

I’ve always believed that if your sleep quality isn’t dialed in, everything else – your workouts, your nutrition, even your mental performance – falls by the wayside. But actually measuring your sleep can feel daunting. Which device is most accurate? Do you really need to wear something on your head at night, or subscribe to an app that spits out data you can’t make sense of?

In this video, I’m breaking down the best consumer-friendly sleep trackers based on scientific literature, validation studies and my own hands-on experience.

Over the years, I’ve tested just about every form of wearable device under the sun, including WHOOP 4.0 (a wrist strap), the Ultrahuman Ring Air, and the Muse S (a headband that leverages EEG technology to measure brainwaves). All of these devices have their pros, cons and ideal use cases.
If you’d rather not wear anything at all, the Eight Sleep Pod system uses a pressure-sensing grid built into a mattress cover to automatically track sleep phases while also regulating bed temperature. It’s an excellent solution if you want effortless sleep data with zero gadgets on your body – although there are serious EMF considerations you should think about before pulling the trigger.

And yes, the latest Apple Watch models can provide basic sleep metrics. Just don’t expect the same detailed insights or targeted coaching as you’d get with the options listed above.

No consumer device is 100% perfect. Even full-blown lab studies fall short because you never sleep the same under observation as you do in your own bed. So don’t get hung up on minor discrepancies. Instead, look for meaningful trends and patterns. Is your deep sleep improving when you skip that evening glass of wine? Does your HRV dip when you stay up late scrolling your phone? That’s the real power of sleep tracking; spotting cause-and-effect relationships, then making lifestyle tweaks to wake up genuinely rested.

In the end, the best tracker is the one you’ll actually use. Check out the links and any available discount codes below if you want to give these devices a try. Let me know in the comments which sleep tracker you prefer. And remember, great sleep is the foundation for a stronger, healthier, happier you.

    How about radiation of those devices?

    Worrying about EMF exposure sounds extreme to me. You’re going to be just fine.

    I have had Oura, Ultrahuman, and several smart watches. I now use the RiingConn, because it has a working Airplane mode so that it is not beaming me with Bluetooth while I am sleeping. When I tried the Ultrahuman it had an airplane mode that didn’t actually turn off the emf’s and I contacted them and they said they would consider it. That was a couple years ago, so I don’t know if they have fixed that. You need to test it with a meter when in Airplane mode to see if it is fixed.

    Can you lift weights with the ring?

    Thanks Michael for this great review of sleep trackers. Doing research on sleep trackers with smart watches – you are correct, most of them are not very accurate compared to some of these other devices like the Muse S. or Whoop 4. Lots to digest here to understand it all hard for the everyday joe to find a simple device to tell you the full story on your sleep tracking or give you enough help to improve it. I hate to say it, but I like my Garmin Fenix 8 and use it with my sleep tracking and as the Chinese say – Chabuduo. Not the best, but enough for me.
