What makes Furlong different
📡

Bluetooth vehicle detection

Connect to your car's Bluetooth and Furlong automatically assigns the trip to the right vehicle. No manual entry, no guesswork.

🏠

Household sync

Traveling together? Furlong detects when multiple devices are in the same vehicle and uses one as the source of truth — no duplicate logs.

🚗

Automatic trip detection

Starts and stops recording the moment you move. No buttons, no check-ins. Your drives are captured even when you forget to open the app.

📋

IRS-ready reports

Export clean mileage logs at tax time — formatted exactly how your accountant needs them, with business vs. personal clearly separated.

🔧

Vehicle maintenance log

Powered by LubeLogger integration. Track service history alongside your mileage in one place, for every vehicle you own.

🔒

Your data, on your device

Local-first by default. Your trips stay on your phone unless you choose to sync. No account required to get started.
