Sure, the name isn’t the greatest, but this little tool is fantastic. Basically, every agile coach knows that you need to take photos of whiteboards, and every photo of a whiteboard either looks super crappy or needs to be processed after the fact to make it presentable. RectAce does it for you. It detects the edges of your whiteboard (or any other major rectangular feature in the photo), and then does all the color and contrast adjustments necessary to make it look nice. Here’s the link to the iTunes store for this app: RectAce.
