Know what your car needs before it becomes a problem, and what a fair price looks like. KarHub tracks your service and gets quotes from local shops for you.
Most car apps do one thing. KarHub is the one that remembers everything — and actually does something with it.
Add your VIN once. KarHub decodes your exact year, make, model, trim and engine, and every answer it gives from then on is about your car specifically.
WHAT YOU GET FREE
• Service history that stays put. Log oil changes, brakes, tires, anything. Date, mileage, cost and notes, in one timeline instead of a glovebox full of receipts.
• Maintenance rings. Every interval is a ring that drains as it elapses, so you can see where you stand without doing arithmetic. Tap one to log it. Add your own for anything KarHub doesn't cover.
• Reminders that do the maths. Oil change due dates calculated from how you actually drive, not a guess. Registration renewals and monthly odometer prompts too.
• Open recall alerts, checked against NHTSA's live database for your vehicle. Recalls are free to fix and easy to miss entirely.
• Nearby repair shops with addresses, distance and directions.
• A tire life guide, the penny test, step by step, and what each result actually means.
KARHUB PLUS
• Otto, your AI mechanic. Ask anything about your car. Otto can see your service history and mileage, searches the web for real specifications rather than guessing, and shows you where each answer came from. Send a photo of a warning light or a leak and ask about that.
• Fluid specs, filled in for you. Otto looks up the oil weight, capacity and fuel grade for your exact vehicle and saves them, clearly marked so you can check them against your owner's manual.
• Quotes, collected for you. Pick a job and how many shops to ask. KarHub emails them on your behalf, reads the replies, pulls out the prices and lays them side by side. You never write an email.
• Booking and reminders. When a shop offers a time, book it in a tap. It goes on your calendar, you get a reminder the day before, and cancelling sends the shop a note.
• Your whole garage. Track as many vehicles as you own.
SUBSCRIPTION
KarHub Plus is $7.99/month or $59.99/year. Tracking your car is free, permanently, the subscription covers the features that cost us money to run.
