Step Tracking Apps

SouthernCountryGirl

I have pedometer on my iphone for tracking my steps when i'm walking outside. i just tried to use it in the house, and it's working, but i'm now wondering how accurately. it kept tracking steps when i was sitting in front of my computer :noway: does anyone know of an app that tracks the steps you take? i would be very interested!! thank you for any help (besides the fitbit, can't afford that right now)
