If you have an iPhone 5S or higher, the Runtastic app can now count your steps during an activity.
You can access this information after your activity when you open the session in the History of the app. There you will see your average and maximum number of steps as well as your step length. The step length is calculated from the distance and step count.
Note: For the steps to be counted, you have to allow the app access to the motion sensor of your iPhone. When you install the update of the Runtastic app you will be asked to do so. If you want to change these settings later on, you can do so in the settings of your iPhone. Go to the settings, select "Privacy" and then "Motion & Fitness". Check if you have enabled access for the Runtastic app.
