Buy apps on one device, download it on another

[Supadoodles]

So, I've used 3 devices....

my iMac, a Macbook, and a friend's iPad.

I bought a paid game on the iMac, downloaded a few free apps on the Macbook, and bought one app on my friend's iPad (after logging into my own account).

Once I get an iPad of my own, will I be able to get the app I bought on my friend's iPad on it? Or is it a one-time-purchase, one-time-download thing?
