We are new Telco in Australia and would like to have our own app built for customers to message each other via IP/3G. An app similar to Whatsapp/Tango etc.
Sending pictures would be preferable too.
This needs to be launched on the Apple Store, Android PLay Store, Windows App store & Blackberry(If possible).
Needs to be very easy to use, no registration required.
Please only bid if you have done a similar project before with references to the app. Please explain how you are going to achieve this with timeframes.
