"I built ARC to solve circadian rhythm issues using science. It's a polished React Native (Expo) iOS app, live on the App Store with RevenueCat subscriptions configured. Why sell? I am a solo developer who loves building 0-to-1, but I lack the time and marketing budget to scale it. With a 96% profit margin and local-first SQLite architecture, hosting costs are $0. Perfect for a growth marketer or portfolio owner who can run ads and scale user acquisition."
