Not working after a week

After reviewing a lot of apps for tracking my crosfit routine I decide on this one since it works with the apple watch. Everything was ok fro a week but then I totally crashed. It only works as a chronometer since it dosent rcord my pulse, intensity... so I lost track of my training at the gym
Big disapointment since Im trainig for an Iron man and this app served no purpose
