BlueDriver App vs WrenchTime: Sensor or Adapter on iPhone?

BlueDriver and WrenchTime in three points

I build WrenchTime, so read this comparison knowing that. I did not test BlueDriver, FIXD or Car Scanner: every claim about them on this page comes from their own store pages and App Store listings, read on November 4, 2026, and each one links to where it was read. Every claim about WrenchTime comes from its own feature documentation.

BlueDriver, FIXD and Car Scanner are trademarks of their respective owners. This comparison is independent: WrenchTime is not affiliated with, sponsored by or endorsed by any of them.

• BlueDriver is a sensor you buy once: the app is free, it needs the BlueDriver sensor, and there is no subscription.
• WrenchTime is an iPhone app for an adapter you choose: it reads live data for free, reads trouble codes with WrenchTime Pro, and keeps the car's maintenance, fuel and trip log.
• They answer different questions: BlueDriver asks what is wrong and how others fixed it; WrenchTime keeps what the car did and what it still needs.

What does the BlueDriver app do?

The BlueDriver app turns an iPhone, iPad or Android phone into an OBD-II scan tool when it is paired with the BlueDriver Bluetooth sensor. OBD-II is the standard diagnostic port under the dashboard of cars sold in the US since 1996. On the US App Store the app is free and the sensor is sold separately, and on November 4, 2026 it averaged 4.6 stars from 14K ratings.

According to the BlueDriver store, the app reads and clears check engine codes and enhanced codes such as ABS, airbag and transmission, generates a Repair Report for each code with possible causes and reported fixes, captures live data, checks smog readiness, and shows freeze frame data. It also shows Mode 6 results, the detailed outcome of the car's own emissions self-tests, such as misfire counts.

BlueDriver's product pages state "Zero Subscription Fees or Add-ons", so the price of the sensor covers the app. The app's version notes on the App Store say that creating an account is no longer required, and an account keeps your scans across devices. The listing is in English and needs iOS 16.6 or later.

BlueDriver Pro vs Next-Gen: what is the difference?

On November 4, 2026 the BlueDriver store listed the BlueDriver Pro Next-Gen at $99.95 and the BlueDriver Pro at $99.95 or $139.95 depending on the colour. Prices on those pages change with their offers, so check the purchase page before you buy.

BlueDriver calls the Next-Gen "the ideal OBDII scanner for newer North American model vehicles" and says it keeps up with newer vehicle protocols. Both product pages describe the same core features: codes, Repair Reports, live data, freeze frame, smog readiness and Mode 6. Each page has a compatibility check for your own vehicle, and that check settles which model fits.

Which cars does BlueDriver work with?

BlueDriver says its sensor works with all 1996 and newer cars, SUVs and light trucks sold in North America, including most petrol, diesel and hybrid vehicles. Code lookup and Repair Reports work on any vehicle with an OBD-II port, according to its product page.

Enhanced diagnostics are narrower. These are the codes outside the basic check engine set, such as ABS and airbag. BlueDriver's App Store listing ties them to the make, the model year and the market, so an owner outside North America should read the table below before buying.

Is BlueDriver bidirectional?

BlueDriver's product pages and App Store listing, read on November 4, 2026, list reading and clearing codes, live data and reports, and they do not list bidirectional controls. A bidirectional tool sends commands to the car, for example to run a component as a test. If you need that, confirm it with BlueDriver before you buy.

WrenchTime is not bidirectional either. It reads data and clears codes on request, and its custom readings use read services only, so a custom request cannot change anything in the car.

BlueDriver's pages also do not say whether its sensor works with other apps. WrenchTime is not tested with the BlueDriver sensor and does not claim to work with it.

What is WrenchTime, and what does it read over OBD-II?

WrenchTime is an iPhone app that reads a car through a Bluetooth LE ELM327 adapter you choose, or an OBDLink MX+, and keeps its maintenance, fuel and trip log in the same place. ELM327 is the command set most inexpensive OBD-II adapters speak. The Vgate iCar Pro, the iCar Pro 2S and the OBDLink MX+ are confirmed on a real vehicle, and the guide to adapters that work on iPhone lists the rest.

Live OBD-II data is free. With WrenchTime Pro, the Trouble Codes tool reads stored, pending and permanent codes from every module that answers the standard OBD-II request, describes generic codes in your language, checks readiness monitors and shows the freeze frame. Codes clear only after a read, with the engine off and after two confirmations. More on what WrenchTime reads over OBD-II.

The rest of the app is the car's record: 59 maintenance procedures with reminders, a tank-to-tank fuel log, EV charging, and trips that record themselves with their engine readings. With WrenchTime Pro it also draws live gauges on CarPlay. BlueDriver's product pages and App Store listing, read on November 4, 2026, list no fuel log, no trip recording and no CarPlay app.

BlueDriver, FIXD, Car Scanner and WrenchTime at a glance

BlueDriver, FIXD, Car Scanner ELM OBD2 and WrenchTime read the same port and differ in what they add to it. "Not listed" means the product's own App Store listing or store page did not mention the feature on November 4, 2026, not that the feature is confirmed absent. For FIXD's free and paid tiers, see FIXD vs BlueDriver in detail.

Which OBD2 scanner should you choose in the UK?

BlueDriver, FIXD, Car Scanner and WrenchTime each suit a different owner, and the right choice depends on what you want from the port. If none of these fits, the best OBD2 apps for iPhone compares more options.

• Choose BlueDriver if you do your own repairs on a North American car, want to pay once with no subscription, and want Repair Reports matched to your vehicle plus enhanced ABS and airbag codes on the makes it lists, on iPhone or Android.
• Choose Car Scanner if you want a low one-time Pro price and a highly configurable dashboard, with Mode 06 and a HUD mode, on a Wi-Fi or Bluetooth LE adapter you already own.
• Choose WrenchTime if you use an iPhone and want the car's maintenance, fuel and trip log next to its live data, readings recorded with every trip, gauges on CarPlay with WrenchTime Pro, and an adapter of your choice.
• Choose FIXD if you want severity explained in plain language and maintenance reminders, and, with Premium, the mechanic hotline, Issue Forecast and vehicle history.

Keep the whole car in one app, with the adapter you choose

If you want live engine data next to the car's service history, WrenchTime shows live OBD-II data for free and reads trouble codes with WrenchTime Pro, which you can buy once for £34.99. The free tier also keeps 1 vehicle with 3 fuel entries and 2 maintenance entries a month and 10 recorded trips a week. See how WrenchTime reads and clears trouble codes. If you need enhanced ABS or airbag codes on the makes BlueDriver lists, or Repair Reports, BlueDriver covers what WrenchTime does not.
