Step GO

Step GO is a health and exercise app that, as soon as it's launched, monitors your steps, exercise time, and calories burned every day. Whether your phone is in your hand, bag, pocket or armband, it automatically records your steps even if your screen is locked.
The signature multi-functional report section, which presents data in a graphical way, can help you understand your daily exercise in more detail. You can view statistics for each item for the past 24 hours, weeks and months just within the report.
Step GO uses built-in sensors to count your steps. There is no GPS tracking, so it consumes almost no battery power from your phone.
