Many photographers enjoy the tactile feel and simplicity of film cameras, but don't want the hassle of actual film. A mobile app could replicate this with basic manual controls and authentic film presets.
Build a camera app with minimal UI, physical dial-like controls, and preset filters mimicking popular film stocks. Offer a pro version with advanced controls for serious users.
The app could monetize through premium filter packs and a one-time pro upgrade. The core experience should remain free to attract users.
Start with a basic camera with 3-5 film presets and simple manual controls. Gradually add more presets and features based on feedback.
The main risk is competition from established camera apps, so focusing on the film simulation niche is key.
