As a huge nerd for all things having to do with Black and White...
This just became one of my most used iphone apps again for photos I post on flickr. I taken and tend to process a lot of photos with the iphone and while I like the Fresh Baked Donuts and Grumplestiltskin forumula it was always the noir chemical and Blackout forumula I really loved this application for (makes your photos b/w)...it does fantastic b/w on your photos and while I feel the best app for b/w is Vint B/W, swankolab pretty much replaces that for me. I tend to use this and monochrome (and PhotoFX) if I am doing b/w. Anyway the newest update fixes the bug glitch that prevented me from using this for sometime. Anyway great app, I highly recommend it, I use this way more than Hipstamatic, which is a fantastic app in itself but I like a lot more control to be given to post processing and not be stuck with a photo I don't have a lot of choice with after the fact.
