About this app

Fixiom is a real diagnostic partner: an AI mechanic that reads your codes, watches your live sensor data, and works the problem with you — step by step — until you have an answer you can act on.

Fixiom is an OBD2 scanner, car code reader, and AI diagnostic tool in one app: check engine light codes, live data, freeze frames, battery test, and a mechanic-grade diagnosis conversation that guides your car repair — with a free scan tool at the core.

No subscription required. The scan tool is free forever, credit packs never expire, and there's no account and no sign-up — ever. You'll need a Bluetooth LE OBD2 adapter (about $25–45, sold separately) for the scan-tool features; the AI mechanic works with just your phone.

Built on the shop floor.

THE SCAN TOOL IS FREE — FOREVER
Pair a cheap OBD2 Bluetooth adapter (about $20) and Fixiom becomes a full scan tool, no subscription, no credits:
• Read and clear check engine codes — with plain-English explanations
• Scan every module on newer vehicles (ABS, airbag, transmission and more)
• Live sensor gauges with real charts, freeze frames, and trip fuel economy
• Battery & charging system test
• Emissions readiness for smog checks

All of that is free for good — no trial, no expiration. The AI mechanic is the one part that uses credits — 25 free credits to start. When you want more: one-time credit packs from $4.99 (they never expire) or plans from $11.99/month. No subscription required.

THE AI MECHANIC
Describe the problem the way you'd tell a mechanic — or just connect the adapter. Fixiom's AI:
• Reads your actual codes and live data, not just generic definitions
• Asks the right follow-up questions, one at a time
• Watches sensors WHILE YOU DRIVE and catches the fault when it happens
• Tells you what it would check next, and why — spark, fuel, sensor, wiring
• Knows your car: recalls, technical service bulletins, and verified wheel-end torque specs
• Explains at your level, from first-time DIYer to working technician

NO ACCOUNT. NO EMAIL. EVER.
Download and start. Fixiom never asks who you are.

WORKS WITH
Most Bluetooth Low Energy OBD2 adapters (Veepeak, vLinker and similar). Every gas vehicle sold in the US since 1996 supports OBD2. Adapter guidance is built into the app.

WHAT FIXIOM WON'T PRETEND TO DO
No tool can fix your car by itself. Fixiom is honest about what it can see, tells you when a hands-on check or a shop visit is the right move, and never invents an answer it can't back up.

What’s new

• Talk to Fixiom — hold the center button and ask out loud. Hands stay on the wrench.
• AI Live Monitoring — describe the problem, drive, and the AI watches the exact sensors while the fault happens.
• Lost the adapter link mid-session? Fixiom now reconnects on its own.
• The adapter guide now tells you where to buy the one we test with.
• Fixed: the AI no longer says "no adapter" right after a reconnect.
• Fixed a crash on first launch on phones with the Android System WebView turned off.
