Collage is another photo editing/creating app for the iPhone that allows you to manipulate your existing pictures and make them into a collage. You'll be able to load up several pictures onto the cutting board and customize them to your hearts content.
The app provides you with the option to change the background to whatever color you choose. Form there you can upload all your different pictures onto the board and arrange them how you like. There's even a tool that allows you to cut them up and move those pieces around.
Once you're done messing around you can click the save button and the collage you've just built will be saved as one of the images on your iPhone. Sometimes the different buttons don't seem to be that responsive and you can't seem to cut through pictures if that's the only picture on there.
If you're a fan of taking pictures with your iPhone and you like to scrapbook or make collages in general, you'll definitely like this app. It's simple and straight forward, yet with the right pictures you can really make it your own. If you don't have a lot of pictures on your phone, then you should probably skip this app.
