Designing and uploading App Store screenshots with a local first JSON project file

Designing and uploading App Store screenshots with a local first JSON project file targets a $600M = 2,000,000 app publishers x $300 ACV, where publisher count approximates active apps and indie/publisher entities doing regular releases total addressable market with medium saturation and a year-over-year growth rate of 8-12% annual growth as mobile app volume and localization demand rise.

Key trends driving demand: Asset complexity growth -- apps support more device sizes and locales, increasing the number of screenshots needed per release; Local-first tooling preference -- creators want ownership of project files and offline access for security and workflow control; Designer workflows converging on canvas editors -- Figma based mental models are dominant, so single-canvas UIs reduce friction; Automation and CI/CD adoption -- teams want scriptable asset files to plug into release pipelines via fastlane or custom scripts.
