The Photographer's Eye for iPad on sale this weekend

The Photographer's Eye for iPad is on sale for Father's Day at 80% off in the iTunes Store. I just bought it for $4.99 and it's downloading now. It's almost 350MB. I'll write a review once I've spent some time with it, but just wanted to let you all know about the offer as it's a substantial discount and it seems it'll only be for this weekend. There's a good review at The Photoletariat.
