title: detect the distance walked
body: <p>I'm thinking of developing an app that finds the distance of user walked. Firstly i tried to implement it via GPS location but is there any different idea with using sensors?</p>
  
  <p>Basicly my app is;
  The user clicks the start button and the walking starts 
  The user clicks the stop button and the walking ends 
  And app says you have walked bla meters.</p>
  
  <p>I want to implement it without location (latitude or longtitude)</p>
  
  <p>Is there any other way?</p>
