Over the past year I built zero, a fully offline expense tracker for Android and iOS.

Most finance apps today rely on accounts, cloud sync, subscriptions, and analytics. I wanted to try the opposite approach:

No accounts No cloud storage No telemetry No ads No subscriptions

All data stays locally on your device. The project is open source and focused purely on privacy and simplicity.

Would love feedback on: • Offline-first product viability • Non-SaaS monetization models • UX tradeoffs when you remove analytics
