Vintage Car Monitor

Vintage Car Monitor is a driving, maintenance, and tuning management app designed for owners of vintage cars — from air-cooled Volkswagens and beyond. - GPS Speedometer Real-time speed display via GPS, with switchable km/h and mph units. The meter's background color can be freely customized to match your car's interior. A Simple mode shows only the meter for clear visibility while driving. - ODO / TRIP Tracking Total and trip distances are measured automatically via GPS. With background GPS support, tracking continues uninterrupted even while you use navigation or music apps. Records are kept separately for each vehicle. - Fuel Management Just record the amount and odometer reading at each fill-up, and the app automatically calculates estimated remaining fuel, range, and average fuel economy. Switchable L / gal units are supported. - Carburetor Setting Records Record and manage carburetor settings such as main jet, idle jet, and pilot screw turns. Multiple carburetors are supported, making it ideal for before-and-after comparisons and seasonal tuning history. - Oil Change Records Log the date, mileage, oil brand, and viscosity. Set a target distance for the next change so you never miss the right timing. - Maintenance Records Keep your inspection, repair, and service history all in one place. Register multiple vehicles and manage each one individually. [Requirements] iOS 15 or later / Japanese and English supported * The GPS Speedometer and ODO/TRIP values are calculated using GPS measurement, so they may differ from actual speed and distance. (To use background GPS, depending on your device you may need to exclude the app from battery optimization. Please refer to your device's manual for details.) * Using background GPS requires your device's location setting to be set to "Always."
