I also knew that of the three pillars of health - nutrition, exercise and sleep - sleep was the one where I needed the most help. Since CES 2018, I had been testing a number of different sleep technologies since sleep was one of the hottest new categories at the show that year.

I gravitated to SleepWatch because it felt like the most polished, most detailed and the one that was most like a feature Apple would design.

So I wanted to see if the Apple Watch actually had strong enough battery life to handle sleep tracking, if I minded wearing my watch while I slept, how accurate its tracking could be, and what kinds of data it could provide.Īfter testing the free versions of several sleep tracking apps. Part of my motivation was that reports had begun circulating that Apple was working on adding built-in sleep tracking to the Apple Watch. It all kicked off last May when I started testing the SleepWatch app and a couple other sleep tracking apps on the Apple Watch. Combined with a couple other apps on the Apple Watch, I was able to improve my stress and track my progress by following Heart Rate Variability.

But it led to a series of events that helped me not only quantify my sleep better than other sleep tech, but also identified a bigger issue: my unhealthy level of stress. When I started using the SleepWatch app on the Apple Watch a year ago, I intended to mostly compare it to other sleep tracking products I had tried.
