I've always heard from my friends that Fitbit's are addictive. I did not believe that one little bit. Recently, however, I downloaded a pedometer (step counter) app called Pacer. It got 5 stars where the Fitbit app only got 3 1/2. I have an iPhone 6 if you're wondering. Anyway, I'm on day 3 of having this app and guess what... I'M ADDICTED!!!...
