On-set prop screens, built for production.

prefx is a professional iPhone app designed for film and TV sets. Swap screen colors instantly, set motion tracking markers, and load custom UI templates — social feeds, news layouts, streaming interfaces — so every prop screen in frame looks exactly right, every take.

Built by filmmakers. Available on the App Store.
