Fitbit is by far the best I have used. Currently, I am using my samsung edge phone for tracking activity. It works wonders. The downfall is sometimes I forget to carry my cellphone while in the office or the battery runs out. But I slightly take it as a win given that there is a surplus of activity unaccounted for...
Stay away from misfit. I ordered an activity tracker from there. Never received it. I waited for a month and a half. I am glad about that though because I saw their reviews and their facebook feedback and my goodness...so many people have headaches with their wristbands and then there are counting errors. It seems like a hassle. I am glad I dodged that bullet.
