I got this as a gift for my birthday and I love it. It's comfortable and lightweight. I like that it has a touch screen to quickly check the time, your step count and other fitness info. I find this to be a huge help in motivating me to get moving and stay in shape. It will vibrate each hour reminding me to get off the couch and move in order to try and reach your hourly goal of at least 250 steps. And when you reach 10,000 steps it's like a little party on my wrist. It vibrates and celebrates reaching your goal. You can pair it with your smartphone to see full stats for the day. I will say that my initial setup had to be done with a computer, although I'm not sure everyone does. It is rechargeable and I usually charge it about every week and a half. It charges quickly. I highly recommend the Alta.
Pictured above is a screenshot of a badge you earn through the app. This one was for reaching 15,000 steps in one day. Below, is a screenshot of the dashboard on my phone through the app. Not shown in picture, but it also tracks sleep, calories burned and your weight loss goals.
