Carkyz: Car Maintenance & Fuel

Track vehicle service with a car maintenance tracker that logs fuel & predicts. Carkyz is an offline car maintenance tracker that helps you stop guessing when service is due. Log fuel, track expenses, and get smart reminders that adapt to how you actually drive, keeping everything on your device with no account or ads required. Predictive Maintenance, Simplified Predict your mileage automatically with a self-learning algorithm that adapts to your unique driving patterns between odometer updates. Receive truly accurate service reminders based on both distance (km) and time (age), because some parts wear while others simply expire. Get notified ahead of time, right on time, and when a task is overdue so you never miss an important service appointment again. Set custom maintenance intervals for any part, from regular oil changes to critical components like brake fluid that degrade with age. Activate a dedicated storage mode to pause all notifications for vehicles you have parked for the season, avoiding irrelevant alerts. Your Car's Full History at a Glance Log every fuel fill-up with comprehensive details like odometer reading, total cost, volume, and whether it was a partial or full tank. Keep a complete and chronological service history for every repair and maintenance task ever performed on your car, motorcycle, or scooter. Manage multiple vehicles in one place, which is perfect for families or for tracking both a work and personal car (up to two are free). Use our car maintenance tracker to build a detailed vehicle log that can improve its resale value or serve as your definitive personal record. See your car's status at a glance, so you always know what service is due next and what you've recently spent. Why Carkyz is Different It works entirely offline, protecting your privacy by keeping data on your device and ensuring you have access anywhere, anytime. It learns your unique driving habits using an EWMA algorithm, providing reminders that are genuinely accurate for how you drive. It tracks both distance-based wear (like tires) and time-based degradation (like fluids) for more comprehensive vehicle care. It's a car maintenance tracker built for real-world use, not just fixed calendar alerts, adapting to your life instead of a rigid schedule. It supports cars, motorcycles, scooters, and other vehicles, making it a versatile tool for all your maintenance needs.
