Oura Ring ($299 and up, $6 a month)
Everyone's favorite smart ring, designed to track your body's signals (sleep, cycle, heart rate stress, and more), can now help guide you through pregnancy, too. The brand recently launched a new health feature, Pregnancy Insights, which can track your gestational age and provide weekly pregnancy insights and educational cards to help you understand your sleep and vitals throughout pregnancy. Pregnancy Insights is still new and there aren't many reviews out there yet, but one of our editors tested out the Oura Ring and couldn't speak more highly of the tech.
"For me, the most useful application has been tracking my sleep. I don't generally have an issue falling or staying asleep, but I do wake up tired often, as opposed to refreshed, energized, and ready to start the day. There are also lots of nights in which I don't get as much sleep as I'd like, and I was curious to see how that would affect my next day. I found that, in fact, when I got a sleep score lower than 80, I did feel more sluggish during the day. Most notably, when my amount of REM sleep was suboptimal, I would wake up with that tired feeling I've become accustomed to." — India Yaffe, former associate commerce editor
