Step Counter Activity Tracker
Is this app "Friendly"?
It helps you track how many steps someone has taken and how much calories they have lost. It lets you set a goal number and each time you walk the percentage of your goal goes up. It's very easy to use. The app is free, you won't need to pay any money to get the app.
My favorite function is that it tracks how many steps you have taken with your phone off or on. It tracks the steps you have done before getting the app, because you have put your information in from the previous days. Great use for the weekends.
