Your streak should mean you actually showed up. C-Rex ties every check-in to the gym you are standing in, so the streak, the XP and the leaderboard are all earned.
Most fitness apps take your word for it. C-Rex does not.
C-Rex is a GPS-verified gym and workout tracker that turns showing up into real progress.
Every check-in is tied to the gym you are actually visiting. Build streaks, earn XP, compete on monthly gym leaderboards and train with people around you.
