Hi hasnainm342,

Welcome to the Support Communities!

It's possible that the app you downloaded is only compatible with an iOS device.  Apps that are compatible with the computer are found in the Mac App Store.  They are downloaded to the Applications folder on your computer.

The following articles will explain more:

Apple - OS X Mavericks - Mac App Store

Can I use my iPhone, iPad, or iPod touch to purchase from the Mac App Store?

No, the Mac App Store can only be used on a Mac.

Where can I find an app once I've downloaded it?

New apps are downloaded to the Applications folder on your Mac, and the app's icon will be placed in the Dock.

Cheers,

- Judy
