We did a team-building activity a few years ago that included creating catapults and launching water balls 50-100 feet. One group made a trebuchet-style device that threw the payload so consistently that the team members could catch the payload. One team member decided he wanted to video it, and had the team launch his smartphone. He caught it, but then dropped it to the grass-covered ground.

I imagine the strong horizontal acceleration and in-flight rotation of the phone may "throw off" (heh) the height calculation, but it likely would have earned an impressive score.
