Building a Mobile App with Claude and ChatGPT: A Non-Technical Developer's Workflow
A developer with no computer science background built a complete mobile application called BloomDay while unemployed, using Claude and ChatGPT as primary development tools. The app is a task-completion garden simulator where users grow virtual plants by completing daily tasks.
Technical Stack and Components
The application was built with:
- React Native for mobile development
- Supabase for backend services
- RevenueCat for in-app purchases and subscriptions
- Cloudflare for infrastructure
- 131 plant illustrations generated using Claude Code
The developer also built the accompanying website and handles marketing independently.
AI Development Workflow
The developer used a specific two-model approach:
- ChatGPT was used to refine prompts and help formulate technical questions
- Claude handled the actual code generation and implementation
This "ChatGPT → Claude pipeline" helped translate non-technical ideas into clean prompts for Claude to execute.
Claude's Strengths in Development
According to the developer, Claude demonstrated several advantages:
- Strong context retention across complex codebases
- Ability to explain why code was broken rather than just providing patches
- Patient responses to basic questions without making the developer feel inadequate
Development Challenges
The main difficulties came from the developer's lack of technical background:
- Difficulty writing effective prompts initially
- Limited ability to recognize when generated code was heading in the wrong direction
- Learning curve for understanding technical outputs
The app is currently undergoing App Store review, with a waitlist available at bloomdayapp.com.
