As we use our iOS device cameras more and more, we get interested in squeezing out better performance from the built-in camera.
That's where QuickCam comes in. It's a US$0.99 app (introductory sale price) that works on the iPhone and the iPad, and the name says it all. QuickCam is really, really quick. In my tests, the app started about a second faster than the stock iPhone camera. Most important for some users, it has a burst mode, where it will fire off a series of pictures very quickly. It is sort of like the old motor drives that started out on film cameras. It's nice for sports photography, and anything where shooting rapid images is important.
QuickCam also takes video, with a twist. While you are taking a video, you can grab stills at the same time, which is definitely a neat trick. Other nice features are a single tap to set exposure and focus at the same time, and a double tap, which sets exposure only. Flash is supported, and of course, both the front and back facing cameras can be used. Saves to the camera roll are very fast. Even in burst mode, as soon as you are done taking your photos, everything is in the camera roll and ready to go.
