Activity tracker HELP!!!

austepants

I have been looking into trackers and finally decided on and purchased the Fitbit Charge HR. I absolutely love it especially the app that goes with it. The problem is I am allergic to the nickel in the band and broke out in a itchy red rash by day 2 of wearing it. I tried making it looser and changing wrists but the other wrist broke out within hours of it being on. My question is do I buy a spandex cover for it off Etsy in hopes it will fix my issue or do I return it and buy something else? I have been researching again and there are too many to choose from. I want it to accurately track steps and distance. I was pretty set on the Vivofit2 but then read how horrible the smartphone app is. I was also intrigued by the Withings Pulse O2 now that they make a watch band for it. I like the trackers that set a daily goal or challenge for you. What are your recommendations? I have an android phone as well.
