I need a cell phone app (IOS). Very similar to "Giftme" or "GYFT".
3 main page - Buy, Sell and Wallet. Addition to this we will have FAQ, Home page etc.
Users should be able to sign in using Facebook or google account.
Payment should be made using bitcoins (bitpay).
Once a buyer purchase E-gift cards. It will appear in wallet. A wallet will convert egift card number and pin to barcode with the store logo.
I need a reasonable estimate and the performance of the app should be as smooth and quick as "GIFTME" and "GYFT"
