## What is Karnos?

Most car apps refuse the entry you actually need to make.

You changed the oil three months ago and forgot to log it. You want to record what the odometer says without inventing a fill-up. You track your inspection by date, not mileage. In most maintenance apps, all three of those are a fight.

Karnos doesn't fight you.

MILES AND MONTHS, TRACKED TOGETHER
Real service intervals are "every 5,000 miles or every 6 months, whichever comes first." Karnos tracks both at once and tells you which one will arrive first, estimating the date from how much you actually drive. Low-mileage driver? It knows your oil is a time job. High-mileage? It knows you'll hit the miles first.

LOG IT LATE. NOTHING BREAKS.
Enter a service you did months ago, at whatever the odometer said then — even if that's lower than today's reading. Nothing is rejected, nothing cascades, nothing needs deleting and re-entering. Made a typo? Fix it, and every projection simply re-reads itself.

UPDATE YOUR MILEAGE ON ITS OWN
One tap from the main screen. No pretend fuel-up required.

START WITH THE VIN
Type the VIN once and Karnos fills in the year, make, model, trim, engine, fuel type and transmission, then builds a starting service schedule so you're not copying reminders out of the owner's manual by hand.

THE GLOVEBOX
Oil filter number, air filter, wiper size, tire size, bulb type, fluid capacities. Written down once, in your pocket at the parts counter.

TIRE SETS THAT KEEP THEIR OWN MILEAGE
Name your summer and winter sets. Karnos banks the miles on each one across swaps, because a set sitting in the garage isn't wearing out.

NEARBY, WITH NOTHING SPONSORED
Your dealer's service center, independent garages, parts stores, tire shops, car washes, fuel and charging. Searches are tailored to your make and handed straight to your maps app, so you get phone numbers and hours. No rankings, no partners, no referral fees, ever.

YOUR DATA IS YOURS
No account. No sign-up. No ads. No tracking. Everything stays on your device, CSV export is free and always will be, and there's a one-tap backup and restore. You should never have to pay to leave an app.

IMPORTANT: Karnos is a record-keeping tool for informational purposes and does not provide mechanical, safety or legal advice. Intervals shown are common values for a typical modern vehicle, NOT your manufacturer's figures — your owner's manual always takes precedence, and every interval is editable. Projected dates are estimates based on the readings you enter and will differ from reality. Recall information comes from NHTSA by year, make and model and CANNOT confirm whether your specific vehicle is affected; check your VIN with your manufacturer or at nhtsa.gov. Karnos never connects to your vehicle or your bank.
