I am taking estimates of different mobile application development companies to make the budget for getting the mobile app developed for my business.

It will be very helpful if anyone could kindly tell me the cost of different place that offers the best mobile app development services.

I wanted a cross platform application developed by a professional, and selected an iOS & android app development firm, but I haven’t contacted them yet or ask for the quotation.

I was hoping first I get the estimates of other places before I talk to them.

Can someone kindly guide me with the cost of the mobile app development services?

Rapid Application Development is a software development method which is entirely based on rapid prototyping and iterative based delivery.

It is a part of agile development techniques but is it any different from Scrum and Extreme Programming (XP) methodologies?

Or does Agile Development itself fall into the category of RAD as its subset?

Because I have heard from plenty of rapid mobile app developers that both RAD and Agile were developed to eliminate the limitations with traditional software development and have the serve same purpose.

Is iterative development the only commonality between them and do both methods work on prototypes?
