iOS app for easily adding a logo featuring transparency?

[alexjholland]

Hey, when I'm out and about, I like to upload photos to our clothing company's Instagram and Facebook pages.

At home, I use Illustrator to add our company logo in vector format to our photos, as it has sections of transparency (obviously I always pick a contrasting colour to the background in the bottom corner that I place it).

Here's an example:

Is there an iOS program that would allow me to place our logo quickly and easily whilst on the move? For every-day stuff it may not be necessary, but some shoot promos I'd like to brand.

Thanks

The most direct method I can think of would be save your vector graphic out as an oversized bitmap with transparency, and use a PS analog like ArtStudio to apply it.
