This is an open question and I was really hoping for advice...
I am planning on creating a mobile app which will track your steps and distance (based on GPS), while sitting in your pocket.
I was planning to make the app out of html5 as I know you can calcualte the motion of the device using this
So, I am really asking if people think this is possible on HTML5?
Thanks
Assuming you know JavaScript, you should be able to accomplish this with PhoneGap's Geolocation object.
Appcelerator has Titanium.Geolocation as well.
