Inspiration

Serving as a priest and musician at Saint Michael Kalibo (ICCEC), I witnessed fragmented communication between missionaries, leaders, and supporters. I dreamed of a unified, real-time platform where prayer requests, mission updates, and team coordination live side by side.

What it does

  • Connects missionaries, leaders & supporters via a live feed
  • Enables prayer request sharing, comments, and “urgent” badges
  • Maps active missions with geolocation and target-amount indicators
  • Offers free trials and subscription tiers (Leader Pro) with feature limits

How we built it

  • Frontend: React Native & Expo Router, Tailwind-style UI, Reanimated for animations
  • Backend: Supabase Auth, Postgres (missions, posts, comments, trials), Storage for media, real-time subscriptions
  • Subscriptions: RevenueCat for in-app purchases, EAS Build with custom dev client to exit Preview API Mode
  • Deployment: Netlify for web landing page, EAS Build for production binaries, GitHub+Bolt.new CI/CD

Challenges we ran into

  • No prior mobile experience—Expo Go’s Preview Mode and native modules required custom dev builds
  • Debugging Supabase relationships (foreign key errors between trial_usage & trial_features)
  • Token limits while iterating trial logic and real-time subscriptions
  • RevenueCat configuration and Android/iOS API key setup

Accomplishments that we're proud of

  • Fully functional, production-ready mobile app with live mission map and feed
  • Integrated mission usage limits and premium subscriptions
  • Automated GitHub ↔ Bolt.new workflow for instant code feedback
  • Launched web landing page at https://www.missionlinker.com

What we learned

  • Mastered Expo custom dev clients to leverage native modules outside Expo Go
  • Built real-time features with Supabase subscriptions for instant updates
  • Implemented robust trial & subscription flows using RevenueCat
  • Gained confidence in React Native, Reanimated, and cross-platform best practices

What's next for MissionLinker

  • Expand mission categories and filter options (region, status, funding goals)
  • Enable in-app donations & integrated payment flows
  • Enhance analytics dashboard for leaders (impact metrics, engagement trends)
  • Localize into multiple languages and onboard ICCEC dioceses worldwide
