Must-have tool for the basics
Photogene is great at doing basic image processing tasks, and the ability to scale images on export is a rather unique feature for an iOS photo editing app.
Having RAW support (works with Leica M8 and M9 DNGs, and that is a nice thing for me) makes it easier to work with RAW than using apps like PhotoRaw (quite good) or piRAWnha (not stable at the moment).
Photogene is not suited for every task, though. But in combination with Snapseed, Perfectly Clear and Photoshop Touch you are good to go!
