As of version 3.1.0 the application has built in support for Pedometers.
This can either be manual entry of steps, using your iPhones built in sensor (iPhone 5S and above have this) or sync with your Fitbit or Jawbone.
This is located on the left hand menu on iPad and on the iPhone please go to the More tab and you will see the Pedometer option.
Please note : Pedometer is an additional purchase within the app
