Grease Genius
Diagnose Your Car, Save Money
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Every other OBD2 app needs a $30 Bluetooth dongle. This one just needs the code you're already staring at. Type it, get the cause, the DIY fix and the real cost. Free.
Stop paying $150 just to be told what's wrong with your car.
GreaseGenius is an AI mechanic in your pocket. Describe what your car is doing in plain English and get a straight answer: the most likely cause, how serious it is, whether it's a DIY job, the parts involved, and a rough cost range. No appointment. No diagnostic fee. No upsell.
Built for everyday drivers, not gearheads.
ASK THE AI MECHANIC
Type it like you'd say it: "shakes when I brake," "ticking at cold start," "AC blows warm." You get the most likely cause, how urgent it is, and an honest DIY-or-shop call - tailored to your exact year, make, model and engine.
SYMPTOM CHECKER - WORKS OFFLINE
Don't feel like typing it all out? Walk through a guided diagnosis and narrow it down fast. The knowledge base is built into the app, so it works with no signal at all - parking garage, roadside, dead zone.
CHECK ENGINE CODE LOOKUP
Staring at a code like P0420? Look it up and see what it actually means in plain English - the usual causes and what the repair typically runs.
SAFETY RECALLS
See every safety recall issued for your year, make and model - straight from the official NHTSA database, free. Includes real owner complaints so you can see what problems other owners are actually reporting.
FIND A PART
Once you know what is broken, price the part for your exact vehicle across several retailers before you buy.
STEP-BY-STEP REPAIR GUIDES
Oil changes, brake pads, tire rotation and more - with the tools, torque specs and safety steps to do the job right the first time and keep the labor money.
BUILT AROUND YOUR CAR
Enter your VIN or pick your year, make, model and engine once. From then on, every answer, part and guide is matched to what you actually drive.
24+ LANGUAGES
Use the whole app in the language you actually think in.

AN HONEST WORD
GreaseGenius is a smart diagnostic assistant, not a replacement for a hands-on professional inspection. A trouble code points at the most likely cause - often that part, not always - and the same repair can cost more on one car than another. So you get the odds, the range, and the right questions to ask. Brakes, steering and overheating are life-safety items: have a professional inspect them before you drive on it.
GreaseGenius doesn't replace your mechanic. It replaces walking in blind.
Your car. Your money. Your call.
