Jeffrey Mincey has A Few Words About App Subscriptions.
There should be no question that app developers– Mac, iPhone, iPad, or whatever platform is chosen– should sell their wares for a price that makes money. The market will decide whether the app is worth the money.
The problem I see so far in the subscription trend is the major jump from a nominal price tag to sum that adds up to significant money very quickly.
Good examples, too. I wish app developers well because they should be rewarded for their efforts, but some of the subscription prices add up over the years.
