Changing Apps Once they have been Published
 

I'm a newbee to the Apps publishing game.
My idea is to publish a free business directory app (eg. Florists) for a local area and then sell upgrades to the listings, such as "tap to call", to individual businesses.
So my question is: How easy is it to make changes to Apps once they have been published for both Apple and Android?
Thanks, Frank.

Unless I misunderstand what you're saying Frank, I think making a whole (I presume you're talking about a native) app just to provide click-to-call is massive overkill. A simple web page would provide this functionality for a tiny fraction of the substantial cost of having an app built just to provide a click to call button. You may also have trouble getting something so simple approved as an "app".

To answer your question, native apps are updated all the time so it's as easy as submitting your changes and waiting for them to be approved.
