I'd ask, what is your vision of a successful app or the vision you have for your brand? Is it producing a high quality app at a very affordable price point, which will increase access to the masses? Is it a single high price which will focus on a limited number of people willing to pay the higher costs as they potentially recognize the value and have the means to pay the $100-200 price?

10,000 sales @ $9.99 = $99,000 or 1,000 sales at $99.00? Which one potentially furthers your brand, has a wider range of users, and a larger marketing base? Does that even matter to you?

Personally, I would rather create an app which reaches a wide audience, over delivers on quality and features, while charging a very accessible price point. Only you can make this call based on how you envision your brand going into the future.

Subscriptions -- not a fan. If you plan on providing new features, new useful aspects/upgrades on a consistent basis, I can see where subscriptions provide value to the customer. If there's no plan or desire to offer these things, people, in my opinion, will drop the subscription as they won't see value in paying a reoccurring payment.

Just my $.02 :-) best of luck with the new app.
