>I don't see a reason to subscribe for apps that are one-time pay and periodic long term use.
This. I'm a developer of such a "sporadic use" app and I don't see how a subscription model would benefit my users. And I honestly wouldn't feel too good about introducing subscription pricing to a tool someone might need once in a few weeks.
On the other hand this might be a solution to the upgrade pricing problem if one could set the subscription interval to 1 year.
Optimally priced annual subscription may work well. Again, this depends on the app's context justifying the subscription model.
One such annual subscription offer that I was totally in favor of was WhatsApp. Given the volume of use I had from the service, I would have gladly paid more. I would prefer subscription to a clean chat service instead of a free service shoving news, themes, icon-packs etc. in my face to make money.
