CL Service is a travel and navigation application designed specifically as an add-on for the Car Launcher PRO app. This free application provides users with the ability to track vehicle maintenance by calculating the distance remaining until the next required fluid or part replacement. It alerts users when they reach a threshold of 1000 kilometers prior to the maintenance due date, ensuring timely upkeep of the vehicle.

Users begin by inputting their current mileage, the mileage at which the last service was performed, and the desired replacement intervals for various fluids and parts. Supported items include cabin filters, engine filters, engine oil, spark plugs, and brake fluid. The app emphasizes the importance of GPS data for accurate mileage readings, encouraging users to manually adjust their mileage periodically for the best results.
