In the settings, I tell the app to take a picture every second, and stop after 300 photos. I set it for "No Video," and to "Store Photos" in my iPhone's Camera Roll. Those are the settings that convert the app into a camera that just keeps taking pictures.

If I'm going to take a group shot, a posed shot or a timed shot -- instead of trying to capture that one moment when nobody blinks -- I use TimeLapse. I just have the app take a picture every second. Everybody poses, and I end up with a few dozen pictures to choose from.

After all, why take one picture when you can take many?

These products represent the early days for cameras that keep capturing by default.
