A timer function is maybe one of the more basic functions that every camera should have. Its so incredibly hard to take stable shots because your finger influences the screen on pressing the shutter button and this gets recorded in the boomerang. Seriously, this app hasnt had an actual feature update since maybe it was created. It needs a timer and a built in stabilizer at the very least.
