Carista OBD2 Bluetooth Adapter vs FIXD OBD2 Scanner

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

FIXD OBD2 Scanner comes out ahead by a narrow margin (4.2 vs 4.3). The gap is mostly about first-time scanner buyers who want plain-English explanations and do not mind managing a subscription — read the strengths below before deciding.

Ranked #5 in Best Bluetooth OBD2 Scanners
Carista OBD2 Bluetooth Adapter
$29.99as of Jun 7

The Carista OBD2 Bluetooth Adapter is the specialist pick for owners of supported VAG, BMW, Toyota and Nissan vehicles who want dealer-level coding and customization, changing interior lighting, resetting services, retracting electronic parking brakes, from a phone app. The free tier handles standard OBD2, but the customization that makes Carista special needs a subscription, and the newest VAG cars are locked out by SFD protection.

Strengths
  • Dealer-level coding and customization for VW, Audi, BMW, Toyota, Lexus and more
  • Unlocks hidden settings like interior lighting, comfort features and service resets
  • Service tools include EPB retraction, oil-service reset and TPMS/ABS inspection
Watch-outs
  • Advanced customization and manufacturer codes require a paid subscription
  • Not supported on newer VW/Audi/SEAT/Skoda (around 2020+) due to SFD protection
  • Brand-specific, far less useful outside the supported makes

FIXD OBD2 Scanner
$39.99as of Jun 7

The FIXD OBD2 Scanner is the beginner-focused pick: its app turns cryptic codes into plain-English severity and likely-cause explanations, pairs over modern BLE, and covers a wide range of vehicles. The basic app is free, but the best features sit behind a premium subscription that the app pushes hard, and the auto-renew has burned owners. Great for novices who watch the billing; underwhelming for power users.

Strengths
  • Beginner-friendly app translates trouble codes into plain-English severity and likely cause
  • Modern Bluetooth Low Energy connection pairs reliably with iOS and Android
  • Free app tier covers basic code reading and clearing for one vehicle
Watch-outs
  • Aggressive upselling and a premium subscription ($99/year) for the best features
  • Auto-renew after the free trial catches many owners off guard
  • Hardware is a basic dongle; the value is the app, not the scanner

How they stack up

Carista OBD2 Bluetooth Adapter

The brand-customization specialist. Unlike the generic-diagnostics focus of the BlueDriver Bluetooth Pro, FIXD OBD2 Scanner and Veepeak OBDCheck BLE, it unlocks dealer-level coding on supported makes, and while the OBDLink MX+ also reaches advanced networks, Carista targets feature customization rather than live-data speed. Like FIXD, its best features need a subscription.

FIXD OBD2 Scanner

The beginner-friendly pick, with the simplest plain-English app of the group. It pairs over modern BLE like the Carista OBD2 Bluetooth Adapter and Veepeak OBDCheck BLE, but its best features need a subscription, unlike the no-fee BlueDriver Bluetooth Pro, and it lacks the OBDLink MX+'s live-data depth and advanced network access.
