This is one of the best workout apps out there. The GPS works really well and with the different settings for sensitivity you can chose how exact you want it to be. This also helps with the battery life if you have an older phone and running the constant GPS signal drains it fast. The different options of biking, walking, treadmill walking, running, stationary bike and aerobics covers most of your workout options also. If you are a social media person using Facebook you can have it post results in your wall and have your friends help you with motivation. I have recommended it to several friends and they are equally impressed.
