Just wait, I think! – Formulas - Photo Lab Effects and Custom Frames Review

This is a good app that will get better as the developer refines it. And Samer Azzam & team certainly will. It makes elements of Stackables easier to use, with the sliders for easy adjustment. I don't care about frames, but these are a great assortment. I would add the basic tools - contrast, saturation, highlight, shadow, etc. Then it will get 5 stars from me.
