OBD-II · Purchase protection · Field tested

Know the car before you buy.

MotoMetrics plugs into a cheap ELM327 adapter, reads live ECU data, flags emissions tampering, captures photos and notes, and turns repair risk into negotiation leverage — on your phone or laptop.

Works in the browser (HTTPS) and as a native iOS app with Bluetooth. Simulation mode available — no dongle required to explore.

Built for real used-car decisions

Not just a code reader — a multi-modal evidence engine that combines OBD data, government safety data, and your own observations.

Live OBD scan

Connect via Bluetooth (Android Chrome or native iOS) or Wi‑Fi bridge. Read readiness monitors, DTCs, coolant, and extended PIDs with clone-safe ELM327 support.

Quick Capture

Log smells, sounds, photos, and seller claims before you negotiate. OCR reads VIN stickers; checklists verify windshield, door jamb, and title match.

NHTSA grounding

Recalls, complaints, and VIN decode from public NHTSA APIs — cross-checked against what the ECU reports.

Auto Analysis monitor

Background sampling while connected learns your baseline and flags gradual coolant, charging, and readiness drift — even when you switch apps (iOS BLE).

Ask Moto AI

Context-aware advisor explains scan results, upcoming repairs, and seller questions — grounded in your vehicle data, not generic chat.

Invoice & repair arbitrage

Audit shop quotes against wholesale parts matrices. Flag markup and match line items to common failure patterns.

How it works

From parking-lot scan to negotiation script in minutes.

Connect

Plug in a $15 ELM327 dongle, pair in the app, and confirm the vehicle bus is live.

Scan

Run a full vehicle scan — readiness, DTCs, VIN from ECU, and financial risk report.

Capture

Add photos, issue notes, and VIN verification while you walk around the car.

Decide

Review score, exposure, recalls, and AI guidance — export or sync sessions to the cloud.
