Yeah I just tried it out and holy shit it's light years better than the default camera app when it come to letting you adjust manual focus and what not. I signed up for the trial. The yearly fee is only $11.99. How did you spend $80?
Australian dollars/app-store pricing, and bought outright instead of subscribed.
Happy with what I paid there.
> In-App Purchases

That is to say, the one-time was immediately easily accessible.
