I need someone to build me an IOS and Android app (same back/front end).
I have a comparative site to use. Should work similarly to the existing app "segundamano"
Potential clients should be able to register to the app via facebok, google+ and email.
Handle credit card payments.
Validator module user accounts via SMS (with cost per message) or by email
Create module users and roles of administration privileges
API Google maps
API OpenPay/[login to view URL]
Open to build a responsive website instead of the apps
