Kotselog

Kotselog is your car's logbook — a private, offline-first companion that tracks everything about running your vehicle in one place. No account needed, no ads, and your data stays on your phone. WHAT YOU CAN DO • Fuel economy — log every fill-up and see your real km/L and running fuel costs over time. • Expenses — track registration, insurance, parts, car wash and every peso your car costs you. • Maintenance & service reminders — record oil changes and services, and get reminded before the next one is due (by distance or date). • Trip logging — record your drives with GPS while the app is open: route, distance, duration and speed, saved to your mileage log. • OBD-II diagnostics — connect a Bluetooth ELM327 scanner to read live data and trouble codes from your car. • Documents — keep photos of your OR/CR, driver's license and insurance handy and private on your device. • Reports — see summaries of fuel, expenses and mileage, and export them. • Fuel prices — keep an eye on local fuel prices. BUILT FOR THE PHILIPPINES Designed around how cars are actually run here — OR/CR documents, local fuel logging in km/L and pesos, and everything usable offline whether you're in the city or on a road trip. PRIVATE BY DESIGN Kotselog is offline-first. Your logs, documents and trips are stored on your device. There are no ads and no third-party tracking or analytics. Location is used only to log the current trip while the app is open — it is never sold or shared. FREE The full app is free to use. An optional encrypted backup and cross-device sync may be offered later for people who want it; the core logbook stays free. Start your car's logbook today with Kotselog.
