Great tool if you don't want to spend so much on a smart watch! You can even compere with friends! I use it to make sure my clients are getting their steps in and calories burned!
My son has the Very Pro-Fit. Pretty basic. Step counting, active minutes, time, and a few other things. He doesn't remember to wear it everyday, but he has had it for over a year, and it is still going strong. I do have to have the app on my phone as he doesn't have a phone, however it updates very quickly.
