Darkroom, a powerful new photo editor and sharing app for iOS, is now available for free on the App Store. One of Darkroom’s more powerful features (Curves) is only available after a $2.99 in-app purchase, but given how much control and precision it gives you while editing your photos I think it’s well worth the cost.

I’ve been beta testing Darkroom for a few months and I’ve been really impressed with it. The developers have managed to get an incredible number of editing controls into the app considering it only being a 1.0 release. From preset filters, undo and revert to original, and their raw RGB control feature their calling “Curves,” Darkroom is shaping up to be a staple application in my iPhone’s photography folder.

They’ve also produced a great introduction video showcasing the application’s more impressive features.
