Not sure what happened but today I just got an increase in user rank of +3 thereby making my current user rank of 36!!! Wohooo!
I've been really quite active lately on using the Actifit app and have not missed even a single day of achieving at least 5,000 activity count but I almost accepted the fact that I will be stuck at user rank 30 forever after being stuck for weeks LOL.
Good thing it started to increase this week. XD
