I am looking for a mobile app developer to create an app for iPhone and Android. I have the source files for the app design. I have a PSD and PDF format. This app will need to use the users voicemail, contacts and access to incoming calls from their mobile device. You will need to sign a non-disclosure agreement to begin the project. The person I choose to be the freelancer on this project will get access to the design, no one bidding will have access to view the files. Please make sure you have worked with or understand the different API's that are required to build this app.
