I am looking to develop an iPhone application where someone can send a "check" to one of his contacts.
The principle is as follows:
Mr. X is part of the application, send a check to Mr Y.
Mr. Y receives an alert on IPhone kind "check that!" . It opens the application, a big hand is on the screen. Mr. Y can complete the virtual check by putting his hand on the screen. It will rock the iPhone and send a warning to Mr. X.
This is the basic idea I have for over a year and a half. I wonder how much it would cost to develop.
Thanks for answering me,
