$15-25 USD / hour

I've had an app created that involves texting. After completing the contract with the initial developer, I've decided I'd like to do some cosmetic work on the app as well as add some additional features. I need someone who can modify the existing code for cosmetic and substantive changes, as well as incorporate a feature involving accessing the phone's GPS. NDA required.
