Ultrahuman RA-RT-Size14-US Smart Ring Health Tracker: Comprehensive health tracking
Why you'll love it:
- Ever wondered what your sleep's really like? Get the lowdown on REM, deep sleep, and those annoying wake-up moments.
- For the ladies: multi-biomarker tracking that doesn't just throw data at you—it gives you the 'why' behind the numbers.
- Stress and recovery metrics that tell you when to push hard and when to maybe just take a nap.
- All the essential features without that sneaky subscription fee. (We hate those too.)
- Bonus: HSA/FSA eligible, because saving money on taxes feels almost as good as a perfect night's sleep.
