The IAP model is a waste of time and energy
While this is a very capable photo editor right out of the box, the IAP model that the developer is using is a real pain, borrowed from the gamers genre, where you do things (like on Facebook, give a five star review here!0, etc.) or pay to get stars, and then use stars to upgrade your effects and filters. Come on, this is not a game app. Put a price on the IAPs if you want to and be done with it. What a waste of energy and time. If you were to just pay cash to upgrade all the filters and lightleaks it would be over $8, I think Ill pass.
