Why we built it

Drivvo and Fuelio have been the default fuel-log apps for a decade. They still work — but they've stagnated, layered in ads, and started selling your location data to whoever's buying. Drivers want the simple promise back: log a fill-up, see your MPG, get reminded when oil is due.

Greenline is that promise. SwiftUI-native. SwiftData on device. No backend except the marketing pages you're reading right now.

What's inside

• Fill-up ledger — odometer, gallons, total cost. We compute $/gal and MPG since your last full fill automatically.
• Maintenance schedules — oil, tires, brakes, plugs, coolant. Predicts due dates from your actual driving rate.
• Stats — lifetime MPG, monthly spend, cost per mile, history charts.
• VIN scanner — point the camera at your registration card. Tap to fill.
• CSV export — every fill-up, every service. Your data is always portable.
• Receipt photos — attach the pump receipt to the fill-up. Mileage deductions, sorted.

What's not inside

• No third-party analytics. No crash SDKs. No ad networks. No location-data brokers.
• No subscription. One-time $4.99 unlocks Pro.
• No account required. Sign in with Apple is not used.

Pricing

Greenline is free for one vehicle with unlimited fill-ups, maintenance, stats, and CSV export. A single $4.99 one-time payment unlocks unlimited vehicles, receipt photos, and local maintenance reminders. That's it.
