Smartphone photographers need better tools for low-light conditions, but most high-quality night photography apps are iOS-only.
Create an Android app with advanced night mode, long exposure controls, and noise reduction algorithms.
Monetize through premium features or one-time purchase, targeting photography enthusiasts willing to pay for quality tools.
Start with basic long exposure and manual ISO/shutter controls, then add advanced features like astrophotography modes.
The biggest risk is competing with built-in camera improvements from Android manufacturers.
