The Concept

An AI-powered habit tracker that connects personal behavior change to verified planetary impact—see exactly where your trees are planted, plastic is removed, or bees are protected on a map.

The Challenge

Traditional habit apps focus only on personal achievement. Users seeking environmental impact can't verify where their contributions go or see tangible results.

Design & Development Process

Phase 1: Brand Development & Product Design (1 day)

Used ChatGPT for concept generation and Midjourney for visual inspiration. Built brand identity and product specs in Figma, including complete visual identity, mobile-first user flows, core screens, and personalized achievement system design.

Phase 2: AI Coach Development (1 day)

Built custom GPT clone trained on BJ Fogg's Tiny Habits principles using a simple RAG implementation. The system queries a behavior design knowledge base before generating personalized recommendations.

Phase 3: Core Feature Development (2-3 days)

Developed habit tracking with streak visualization, GreenSpark API integration for verified impact, interactive map showing contribution locations, timeline of all impact actions, daily emotion tracking, and personalized achievement system.

Phase 4: Testing & Iteration (1-2 days)

Personal testing, bug fixes, mobile optimization, and UI refinement based on usability issues.

Results & Learnings

What Worked

  • • Rapid prototyping: Concept to functional prototype in 2 weeks
  • • Validated core hypothesis: Users want verified impact alongside habits
  • • Skill development: Learned modern dev workflows, AI integration
  • • AI-assisted development: Built features beyond previous technical ability

What Didn't Work

  • • Never reached production readiness (no payment integration)
  • • Hit technical complexity ceiling without engineering support
  • • Replit hosting costs ($25/month) unsustainable for demo
  • • No monetization validation

Key Insights

Vibe coding is powerful for MVPs — Tools like Replit enable rapid hypothesis validation, but production applications require professional engineering, proper infrastructure, and scalable hosting.

This project demonstrated that the barrier to building has dramatically lowered—a non-engineer can build a multi-faceted application integrating AI, APIs, and complex user flows in two weeks with $80.

If I Built This Again

Technology:

Swift native iOS with Cursor/Claude Code

Process:

  • • Comprehensive product spec upfront
  • • Strict MVP boundaries
  • • Plan production architecture from beginning
  • • Bring in senior engineer as coach
