App purchase, 2 devices, 1 Apple ID. Do I get charged twice?

I purchased an app downloaded on 2 Macbook pros using same apple ID. Do I get charged twice?

I purchased keynote on my mac.

My mac is broken so I'm using my dad's mac for now.

I needed to use keynote for work so I downloaded it (again, in a sense)

from app store using my dad's mac and my apple ID.

Will I be charged for it again?
