Any ELM327 Bluetooth dongle works. Already have a scanner? Use it. We don't lock you into our hardware.

Live parts pricing

We scrape real-time prices from AutoZone, Amazon, and RockAuto. You always see the actual cheapest option, not a flat estimate.

Guided repair tutorials

After identifying the code, we generate a step-by-step DIY tutorial built for your vehicle year, make, and model.

No subscription

Pay once, use forever. No monthly fees. No premium tier gates. Full access from day one.

Full system scan

Read engine, transmission, ABS, and SRS codes. Most apps only show engine. FixNow shows you everything.

Repair history log

Every scan, every code, every fix — saved automatically. Track your car's health over time.

You don't need a mechanic. You need the right information.

Most people pay shop rates for problems they could solve in their driveway with a $20 part and a YouTube video. FixNow closes that gap — giving you the diagnosis, the parts, and the instructions all in one place.

No surprises. No subscriptions.
