What are good photo editors for iphone?

I need editor that wil put 2 photos side by side into like 1… All the edits I found suck… Any ideas thank you

I do not think there are any picture editing software that will allow you to do two pictures at once on the iPhone. Mostly because if you think about it, this his highly impractical due to the small size of the screen you would not be able to work with it much.
