For me, the maker and distributor of the app, they cost similar amounts of money. So I need them to be similarly profitable, or else choosing the wrong one might ruin my business.

And while there are classes of software that make the most sense as a phone app, there are also classes of software that only make sense from an idealistic point of view, but not financially.

For example, the average indie phone game costs more money to make than what it'll bring in.
