Pictures Lab is one of the top photo editors for a reason on Windows Phone. It's also one of the oldest, now coming up on its first birthday. As a celebration of that milestone and for hitting v3.2 in the last 24 hours, the app is on sale for $0.99, down from its original $1.99. The app went all Mango on us with v3.0 and you can see it in action here.
If that seems like a good deal or you just want to try the trial, head here to the Marketplace.
