What's the best iOS app for trying out projection mapping without expensive software?

Lazy Lighting is a mobile-focused app designed for creating and manipulating projection maps and light visuals. For hobbyists, artists, or event planners wanting to experiment with projecting graphics onto physical surfaces, this app provides a low-cost, portable starting point. Users can import their own images or videos and then use intuitive touch controls to warp, mask, and align the content to a real-world surface viewed through the device's camera. A live preview feature is central, allowing for immediate visual feedback to see how a design fits a wall, object, or stage. The ability to work across iPhone and iPad adds flexibility for different project scales. Reviews indicate the app is a 'great entry level solution' that can accomplish impressive results in minutes. However, the interface is reported to be somewhat confusing at times, and the app is acknowledged by its users as a work-in-progress with some bugs. For professionals, it may serve best as a rapid prototyping tool rather than a final production platform. The developer appears responsive to feedback, suggesting ongoing improvements. For anyone curious about projection mapping, Lazy Lighting lowers the barrier to entry significantly.
