Apple/Android App

We require an app to be developed for Apple, Android & Blackberry devices. The process from start to finish includes developing the apps, through to launching the products onto the App Store and Android Markets. Brief Description: The app will entail 5 screens, with basic mathematical calculations in 1 screen. App design, development, logo and launch are required. The app is very simple and is for professional use, and the design needs to reflect this. Further details will be discussed after a Non-Disclosure Agreement is signed. Requirements: * Experience in designing and developing for iPhone and Android apps (Please show me your best iPhone Apps that were developed by you). * Ability to work at a fast pace, take direction, understand and follow instructions. * Fluent English. Payment 20% down payment before project starts. Balance of payment will be released once both apps are functional and approved on the App Store and Andriod Markets. I look forward to hearing from you.
