Sweeeeeet
This app is seriously great in a number of dimensions.
1) The layout is super easy to use
2) There are many options to adjust, resize & recolour individual pics within the "collage"
3) You can save them to your device or send them after youre done.
I use this app to show sequences of events or foods for my instagram :)
