I don't know, this sounds really silly. It's better to raise purchase prices; of course nobody would make living off $0.99 apps. But how many people would be willing to pay you a recurrent tax on your software either? Very few. How many apps would you be willing to keep if you needed to pay subscription? Yes, there was a race to the bottom in mobile apps, as the space was pretty new and trivial apps were feasible; for those it worked very well. The situation is different, ad revenue is falling and one-off prices are too low. Just increase them then!
