Duepost: Car Maintenance Log

Your service history should never be locked behind a subscription. Duepost logs oil changes and other maintenance, shows what's due next by mileage or date, and keeps everything on your phone. Logging, due dates, reminders, service history, cost totals, CSV export and backup files are free. No sign-up, no email, no password, no ads. WHAT'S DUE, AT A GLANCE • Enter your odometer and when each item was last done. Duepost works out the next due mileage and date on your phone and lists Overdue first, then Due soon, then No record, then OK. • 10 common items: engine oil & filter, tire rotation, engine air filter, cabin air filter, brake fluid, coolant, wiper blades, battery check, spark plugs and safety inspection. • Severe driving (mostly short trips, towing, dusty roads or stop-and-go traffic) shortens the intervals. • Service reminders: a notification on your phone when an item is due soon and when it's due. • Miles or kilometers, more than one car, light and dark themes, English and Korean. LOG A SERVICE IN SECONDS • Tap an item and enter the date, the odometer and an optional cost. Logging a higher reading also updates your car's odometer. • Edit or delete any record, with undo. • History grouped by year, with spending for this year and all time. • Export a car's history as a CSV file for a buyer, a spreadsheet or your mechanic. AI PLAN FOR YOUR CAR (OPTIONAL) Want intervals tuned to your exact car? The AI plan suggests an interval and a one-line note for each item from your car's make, model, year, fuel, driving conditions and rough monthly distance. Every suggestion is kept within that item's safe range, in the app and on the server, never longer. Your owner's manual always wins. AI can still be wrong, so you can report any result in the app. Only after you agree, Duepost sends make, model, year, fuel, driving conditions, monthly distance rounded to 100 km and the app language. Never your odometer, service records, costs or license plate. SOMETHING FEELS WRONG? Duepost does not diagnose problems. Describe what you notice and the app checks it on your phone only; nothing you type is sent. Warning lights, noises, smoke, leaks or brake trouble get a clear "see a mechanic" message and a map search for repair shops. PRO SUBSCRIPTION 2 AI plans are free. After that, AI plans need Pro, an auto-renewing weekly or yearly subscription. Google Play shows the price and any free trial before you confirm. Pro removes the 2-plan limit within fair-use limits, and AI plans may pause for everyone when the app's daily AI budget is reached. Cancel anytime in Google Play under Payments & subscriptions. Logging, due dates, reminders, history, export and backups never need Pro. YOUR DATA • No sign-up: no email, no password. • Cars, records, costs and odometer stay on this phone. Android cloud backup is off, so save a backup file wherever you like (Drive, email, a computer) and restore it on a new phone. Restoring replaces the cars and records on that phone. • Delete all data in Settings, and turn off AI data sharing at any time. Intervals are general guidance, not a vehicle inspection. Duepost is not affiliated with any vehicle manufacturer.
