"Pedometer+Walk weight loss" is a free iPhone app developed by Techathalon Software Solutions PVT LTD. It utilizes the iPhone's built-in pedometer to track your steps and provides valuable information about your physical activity.

With this app, you can easily record the number of steps you have taken, along with the number of calories burned, distance covered, and walking time. The app also calculates calories based on your weight and distance, and adds them to the HealthKit store.

Using the app is simple - just give all the necessary permissions and hold your smartphone as you normally would while walking. The pedometer will continue to automatically record your steps, even if you put your phone in your pocket or bag, thanks to its vibration pattern-based step calculation.

This app not only quantifies important metrics such as steps taken, calories burned, and distance covered, but also rewards you once you achieve your goals. It also uses HealthKit permission to import calorie-related data from the app to the HealthKit store, allowing you to access and share this data within the app.

Overall, "PedometerWalk Step Weightloss" is an easy-to-use and feature-rich app that helps you track your physical activity and reach your fitness goals.
