Ive had that app for a long time. Ive never completed a whole challenge because Ive either gotten lazy, or my phone got messed up, etc. I really enjoy this app. The longest Ive gone is 12 days and I had AMAZING results. So, imagine how great the 30 day result will be! I recommend this to anyone willing to put time in to do this daily.
