Some phones have problems using e.g. Endomondo while not getting accurate GPS location info. Without and with Tracker Booster result images attached. Google Maps looses the GPS signal when phone falls into power saving mode. This application keeps the GPS busy so that Google Maps is always in correct location when you need it.
