Film crews often need phones, tablets, and monitors to show believable interfaces on camera. Dead screens push work into post-production; rigid mockups cannot respond naturally to a performance.

Baffe supplied the product requirements. My job was to turn them into a production iOS application and ship it.

I implemented the initial app independently in SwiftUI, including configurable digital-prop surfaces, production controls, local media, purchase entitlements, and the scene lifecycle required to drive connected displays.

• Customizable messaging, social, streaming, news, live-feed, chroma, and RGB experiences.
• Independent external-display output for USB-C/HDMI and compatible display routes.
• Local-first media behavior appropriate for on-set use.
• RevenueCat and StoreKit subscription and lifetime-entitlement paths.
• iPhone and iPad layouts, orientation handling, and App Store delivery.

The difficult work was not simply drawing realistic screens. The app had to keep editable template state, production controls, media playback, entitlements, and external-display scenes coherent as devices connected, disconnected, rotated, or reset between takes.

The architecture separates the control surface from the presentation scene so a crew member can configure an experience without exposing controls on the display being filmed.

After the initial production release was complete, I handed the application to Baffe. Baffe now owns the product and continues to maintain and improve it. Current App Store screenshots may include later Baffe updates; this case study claims only the initial application and features I can verify from my delivery source.
