What people say. Recommended for its data-driven analysis of Apple Watch sleep tracking and heart rate accuracy.

On “Apple Introduces Apple Watch Ultra”

Apparently, the Apple Watch link to this video . link reviews all the sleep/heart trackers and records accuracy. He’s a professional scientist specialising in sleep research and the reviews concentrate on data/accuracy only.

On “Analysis of Apple Watch running data”

For anyone interested in heart rate accuracy and sleep tracking accuracy I will recommend to check The Quantified Scientist reviews . From his latest reviews of the new apple watches, heart rate is pretty much on par with chest strap and sleep tracking is also far better than anything he tested.

Apple Watch was not tested, so for anyone interested, here are two videos by "The Quantified Scientist" creator Rob ter Horst, a postdoctoral researcher who specializes in bioinformatics (studying biology using machine learning and statistics).

On “Apple Introduces Apple Watch Ultra”

Kind of... Apple's sleep tracking is by far the best on the market1. However if your watch doesn't last many days it's a pain in the ass to use it that way, because you charge it overnight instead of tracking your sleep. 1 link to this video

On “Study uses wearables to show that physical activity lengthens REM latency”

I find my Apple Watch information useful. I don't remember when I fell asleep but my apple watch does. This keeps me honest about going to be too late. Additionally, when I first got it, I found that I was only getting 40 minutes of deep sleep which is why I was always somewhat tired. After adding magnesium to my diet I am getting around 70 minutes of deep sleep. I wouldn't have been able to pinpoint this without the data. The apple watch is the best sleep tracker 1 so your data might be too noisy to find results. 1 link to this video
