An app for Apple devices released in 2011 allowing you to overlay various action movie VFX over self recorded video.
One of the most recognizable, and probably overused effects, is "Side-Swiped" where a car is hit from the side by a police car.
The app (and stock videos) later gained resurgences around 2023 as a part of various ironic shitpost meme videos, often without removing the green screen for comedic effect.
