Great utility, better UI

The featureset of this app is exactly what I needed. The UI is very polished and it is obvious the developer took care of the interface both at a macro level, by laying out the core functionality at the center front, and at the micro level by taking care of screen transitions, help messages... I would recommend it to anyone.

Very fast & easy!

This was exactly what I needed to combine some screenshots. It was so fast and easy!

Work in Progress

Can't overlap images. Can't rotate one image slightly to manually align. I just spent $2 to tell the developer what he/she already knows.
