About

RC Maintenance Timer

Features
Read full description

Know when your RC car is due for service, before a worn part ends your day early. Set a maintenance schedule once, add your runtime after each run, and the app shows what needs a check, a rebuild or a replacement next, with reminders so you never fall behind. HOW IT WORKS 1. Add your car. Your first car comes with ready-made maintenance tasks for common parts, such as bearings and tires & wheels. 2. Set when each task is due, in minutes of runtime: Check, Clean/Rebuild and Replace. Change the defaults or add your own tasks. 3. After each run, add how many minutes you drove. 4. The Home screen shows what is due next on each car and how many minutes are left. 5. Did the work? Tap Mark done to reset that counter. Tapped it by mistake? Double tap to undo. WHY IT HELPS - Fewer breakdowns. Regular checks catch worn parts before they fail. - Spend less on parts. A tired part replaced on time costs less than the damage it can do. - Stop guessing. Service intervals follow how much you actually run, not the calendar. - Keep every car ready. See at a glance which one needs work before you head out. FEATURES - Maintenance schedule based on real runtime - Three intervals per task: Check, Clean/Rebuild and Replace - Total runtime for every part and for the whole car - Reminders on the days and time you choose, so you never forget to add your runtime (sign-in required) - Add and edit your own tasks and intervals - Works for any RC car or truck, electric or nitro, on-road or off-road - Available in 13 languages - Dark mode SIMPLE PRICING Free with one car. A one-time $4.99 Lifetime Backer purchase unlocks unlimited cars. No subscription and no ads. To finish first, first you have to finish.
