I wish there was a way to add a timer delay that way we can use the front facing camera and create Boomerang videos without having to have someone else there to push the button to start recording. The app is pretty simple, no real features that I could see, thats why I gave it 3 starts. A delay timer would definitely make this app much better! :)
