Is it possible to install an iPhone app in MacBook Pro?
Nope.

The only way you can run iOS apps on OS X is if you have the iPhone Simulator and have a version of the app specifically compiled to run on the simulator.

The iPhone Simulator (available from Xcode) is not an emulator and can't run ARM code, which means that it has to run a specific version of iOS 7 designed for OS X, and is not able to run iOS apps that have not been designed to run on this version of iOS 7 (i.e. IPAs from the App Store).
