Honestly, i never counted my steps neither ever trusted on those apps. Even I uninstall #actifit app after few checks. As said intention is more important than attention. If you really have the intention for a healthy well being, many things needs to focus on rather than mere counting the steps. I personally belive if you focus on number of steps then you carrying an extra burden on your mind and it does not going to get you the results. Focussing on walk and then stretching your body gives out a better result. I usually walk for 3km, I never looked at the distance but finding my body fits this distance I am ok with it.
