StepTracker Fitness Pedometer is a health and fitness app designed for the iPhone. It utilizes the iPhone 5S's M7 motion co-processor to automatically track your steps throughout the day, providing insights into your activity levels and helping you lead a healthier lifestyle. Unlike traditional pedometer apps, StepTracker doesn't need to run in the background, ensuring minimal battery consumption.

With StepTracker, you can easily access your step count history, add comments to your data, export information, set daily goals, and even compete with friends via Game Center. The app offers a user-friendly interface, displaying step counts in various formats, including graphs, and providing a Notification Center Widget for quick access to your progress.
