Garmin Vivoactive at a great price (seriously great) I jumped on it. It tracks a ton of things: steps, walking and running (with maps), biking (with maps), indoor treadmill and stationary bike, golf, and swimming.
Since I was planning on swimming...bonus.
And so far, this has been my favorite activity tracker. I connected it to my cell phone and get a gentle buzz when I get a text message (which I need because I can never hear the phone when it's in my pocket), I get a repeated buzz when I have a phone call (which is always a wrong number), and if I sit too long, I get 2 short buzzes to remind me that I should get up and move.
But damn, Garmin...when I get a movement reminder in the middle of a game of racquetball that's drenching me in sweat and making me think I want to drink half the swimming pool...that's kind of offensive.
I am moving, dammit.
So fine, I'm not moving all that well and I play a sucky game of racquetball but you don't need to rub it in. Sheesh.
