The entire process consists of: project analysis, UI/UX design, development & QA testing, and support.
Analysis: gather and analyze all the project requirements and documentations.
UI/UX design: create wireframes, prototypes, and design the app screen by screen.
Development & QA testing: build iOS and Android apps using cross-platform framework React Native paying attention to proper QA-testing.
Support: publish the game in the App Store and Google Play. Plus, provide post-launch support if needed.
