So I know y’all, like me, have Fitness Tracker Burnout. Pebble! Fitbit! Garmin! Apple! Misfit! Jawbone!
(I’ve owned three of those, so I’m right there with you.)
But this, it might still be worthwhile:
That’s titanium ring with a tracker crammed into it, and according to the MacWorld review it works pretty darn well: three day battery, two colors available, comfortable and basically invisible.
I’d get the gray version, but for me a ring is much more interesting; even the Apple watch wasn’t able to displace my beloved wristwatches from my wrist forever, and I’m unwilling to wear a watch on one wrist and a tracker on the other.
