You've taken a great photo, or so you think, but darn, the camera moved ever so slightly and you lost the shot.
Anti-Blur Camera (US$1.99) gives you a better chance at getting the photo you want, by taking a series of 4 photos and automatically saving the one that is the best.
Start by framing your shot. The app begins shooting as soon as the camera is steady, even if you haven't pressed the shutter button. Once four images have been taken, Anti-Blur Camera analyzes each one and selects the best one to save. You can view all four images while the app is running if you'd like to see the other three.
This is a bit different than the burst mode that Apple builds into the iPhone camera. That feature takes several pictures while you are holding down the shutter button. It can be used to find an image with sharp focus, but it's mainly for finding the perfect moment during a sporting event or the best smile in a portrait.
