There has been a bit of a rush on filter apps, but this is steps above the others as you can see the effects in real-time. The app also lets you convert videos and photos you've already shot. The filters mostly look great too, which is more than I can say for the other filters I've messed around with lately. $4 was a little steep, but at $1.99 it's a lot more palatable. App info is currently processing and/or the app is not yet fully available for sale on the US App Store.
