Show HN: Stintly – Offline-first app for freelancers with on-device AI

I built Stintly, an all-in-one business management app for freelancers, contractors, and self-employed professionals. It runs entirely offline with all data stored locally on your device.

What it does: - Invoicing & estimates with on-site signature capture - Expense tracking with receipt scanning and voice input - Time tracking with one-tap timers - Job/project management with photo documentation - Schedule C tax tracking with quarterly estimates - Client management with revenue history - Reports & analytics with PDF export

What makes it different:

Privacy-first: All data lives on your device. No account required. No tracking, no ads, no data selling. Optional iCloud backup if you want it.

Offline-first: Works 100% without internet — SQLite on device. Most competitors (FreshBooks, Wave, QuickBooks) require a connection.

On-device AI: 20+ AI features (receipt OCR, voice expense entry, cash flow forecasting, tax optimization, client insights) run locally via Llama on Metal GPU. No data leaves your phone.

Tech stack: React Native/Expo, SQLite, NativeWind, on-device LLM via react-native-llama.cpp with Metal acceleration, custom OTA updates via Cloudflare Workers + R2.

Pricing: Free tier (5 clients, 5 invoices, unlimited use) forever. Pro at $12.99/mo, Premium with AI at $19.99/mo.

Currently on iOS (iPhone/iPad/Mac). Would love feedback from other freelancers and indie devs on what's missing or what you'd want from a tool like this.
