Key Features

  • Real-time display which shows PID data in your choice of graph or chart;
  • This car device diagnostic has detailed code definition reports to help both car owners and mechanics;
  • In-app logbooks for service sessions, consumable items, and service interval tracking; and
  • Issue-clearing feature for vehicles manufactured from 1996 (gas) and 2008 (diesel)

Developed by a company operating out of the US state of Georgia, FIXD – or, to give its proper name, the FIXD OBD2 – is an automotive on-board diagnostic (OBD) system that enables car owners to gain relevant information as to the operative health of a vehicle. In doing so, they are better informed about critical issues and are able to give their mechanics a concise description in order to facilitate appropriate repairs.

Among FIXD's sterling virtues are its ability to pinpoint almost 7,000 issues transmitted to you through its car health ap. This could, at one time or another, activate your dashboard's Check Engine light, as well as its comprehensive library of issue codes that help mechanics determine the best course of action for repairs.

bluedriver 1 2

Key Features

  • Starts scanning and reading codes almost as soon as you plug it in;
  • Programmed to generate reports after all diagnostic scans;
  • Generates Mode 6 results for OBD monitors;
  • Screenshot/system shot feature to give users a tangible record of any issues encountered;
  • Preparatory features for emissions and compliance testing; and
  • Real-time data support

Much like FIXD, Bluedriver is also a plug-and-play car health check device that you can sync with the car health app on your phone or tablet as soon as you lock the scanner into your car's OBD2 port. 

But that's where the similarity ends. As easy as FIXD is to use, it takes time to learn how Bluedriver works and to use it properly. Also, Bluedriver tends to drop the connection when you try to sync it with your device via Bluetooth – and that's an issue we encountered on both Android and iOS devices.

We would also like to point out that there are a number of critical codes missing from the Bluedriver service library, which puts this device at a disadvantage. (And, for its price, it doesn't seem worth it.)

What Exactly is a Car Health Monitor?

Car health monitors, also known as vehicle health tracking systems, are tools specifically developed to check your vehicle for any issues that could affect its safety and performance. For the most part, these can check a car's engine data, any diagnostic codes, its current battery levels, as well as mileage and wear. 

Contemporary car health devices give users and their mechanics solid reports regarding the state of a vehicle's health, as well as a comprehensive look at value-added features like automatic braking and airbag deployment, and whether consumables need to be replaced.

Currently, these come in two forms: those that use telematics which call for integration with different internal and external communications systems, and those like FIXD and Bluedriver that utilize second generation OBD (OBD2) technologies. In fact, all vehicles manufactured after 1996 (gas engine) and 2008 (diesel engine) are required by governments the world over to be OBD2 compliant.

How We Chose the Best Car Health Monitor

When we did our search for the best car health monitors, we took the following criteria into consideration:

  • Overall performance in terms of diagnostics, specifically the number of issues or codes the system can accurately and instantaneously identify;
  • Data storage to give car owners a point of reference for future repairs or tune-ups;
  • Ease of use, particularly when it comes to basic system instructions and interfacing with compatible mobile applications;
  • Upgrade-readiness to ensure compatibility with later car models;
  • Ready customer service and the overall competence of technical support; and
  • Overall value for the customer's money.

Conclusion to our Guide on the Best Car Health Monitor

OBD2 scanners like FIXD and Bluedriver go a long way when it comes to help you keep your vehicle in the best working order. For this guide, we consider FIXD as our best car health monitor.

Please note that, in the interest of getting authentic car health monitor, we recommend that you shop for the best car health monitor through their official websites. You may also get great discounts for multiple purchases. Beware of purchasing from marketplace sites claiming to be resellers so to avoid issues with refunds and returns in the future!
