OBDAssistant vs. FIXD

How OBDAssistant's open hardware approach and AI repair models compare to the FIXD proprietary subscription service.

FIXD Scanner

A closed ecosystem requiring proprietary sensor hardware ($59) and a paid premium subscription ($69/yr).

  • Proprietary Hardware: Locked to the custom FIXD Bluetooth adapter; standard third-party adapters are blocked.
  • Subscription Paywall: Crucial features like emissions readiness tests and repair cost estimators are locked behind yearly paywalls.
  • Limited Telemetry Graphing: Focuses heavily on basic code translation; lacks deep multi-sensor custom PID telemetry dashboards.
  • Generic Fix Database: Relies on generalized repair code definitions without custom mechanic-vetted resolution lists.

OBDAssistant

An open-access AI OBD2 scanner app that works with any generic $15 Bluetooth adapter.

  • Universal Adapter Support: Works with ELM327, Veepeak, OBDLink, and standard BLE Bluetooth dongles.
  • Free Basic Diagnostic Scans: Read codes, view freeze frames, and clear check engine lights without a subscription.
  • High-Frequency Live Data: Graph multiple PIDs (MAF, short-term fuel trim, O2 voltage) concurrently in high resolution.
  • Verified Autoworks Fixes: Direct access to mobile mechanic workshop repair databases for verified fixes.
