Run Tracker: Best GPS Runner to Track Running Walk

The app did not keep track of time correctly. It said 3 minutes on a run that took over 30 minutes. It did not give indication of time or distance during the run. After, the map was not stored to be viewed at a later time. There was no possibility to convert miles to kilometers or the calorie count from Ibs to whatever. Calorie count could possibly be more accurate by letting the user enter weight and height? This app needs severe improvement.
