What app is used for automatic timer camera?

This self-timer camera app not only has countdown timer but also snaps multiple photos with delay in between since no one takes just "1" photo. :-) You can adjust the number of countdown seconds before photos begin, and you can adjust the number of photos you want your camera to take. Beeps will alert you when camera is getting ready to snap and also when photos are complete, so you know the status of when its done.
