It got Highly Recommended for "makes the process more accessible for home users." In 2025, described by the Products Writer and tester for CAR and Parkers, Aaron Hussain, as "Score: 4/5.

Our Origins
Written by the company
- An $8,000 repair estimate. An $80 fix.
- One of Carly’s founders was told his car needed repairs costing nearly $8,000—more than the car was worth. Like most drivers, he had no way of knowing whether the diagnosis was accurate. Instead of accepting the bill, he dug deeper. By accessing the car’s hidden data, he uncovered the real issue: a small component that cost just $80 to replace. The problem wasn't the car. It was the lack of transparency. Today, Carly gives drivers direct access to their vehicle's data, helping them understand issues, avoid unnecessary repairs, and make smarter decisions about their cars. That's how Carly was born.

I would buy a general scanner which supports BMW without any ristriction including resetting the error code. I had to buy one when I sold my BMW Z4 to reset lot's of error codes which were turned on when I repair some parts.
It would be a lot cheaper than this.
However if you want to program specific BMW codes, this is the best.
Be careful not to charged wihtout known. Unscribe immidiately if you want to use only one time which you can use for a year. If you forget unsubscribing, you will be charged every year. Carly wants your money even though you don't use it. The default setting should be unsubscribing when it is not renewed intentionally. Auto renewal should not be applied by Carly!

We’re sorry that Carly did not feel like the right solution for general BMW diagnostics and error-code resetting in your case. We understand your point that a general scanner may be a better fit if someone mainly wants a one-time tool for clearing many fault codes.
Carly is offered as an annual app license that unlocks the paid Carly Functions in the app, including brand-specific features where technically available. The automatic renewal is part of this license model and is shown during the purchase process, but we understand that renewal expectations must be very clear, especially for customers who only plan to use Carly once.
Your feedback about diagnostics, pricing, and automatic renewal is important to us. It helps us improve how we communicate the license model, renewal settings, and the differences between Carly and other scanner solutions before purchase.

Fraudulently charged my credit card $109.88 for something I never signed up for, nor purchased. If you've ever bought any of their products, pay attention to the corresponding account. And now, when I attempt to use their app, it's like my entire profile has been deleted. Seems very shady.

We’re sorry to hear about the unexpected charge and the issue accessing your Carly profile. We understand why this would feel concerning, especially if you do not recognize the purchase.
Carly is offered as an annual app license that renews unless automatic renewal is disabled before the next license period begins. The license terms are shown during the purchase process, but we still want to review cases where a customer does not recognize a charge or cannot access the related Carly account.

Twice Charmed
I've ordered from this company twice now - initially for my introduction to their product and app experience, which went splendidly, and again to renew my licensing and continue with a different vehicle.
In short? They're excellent.
Highly recommend diving into the world of diagnosing your vehicle status and codes, as well as enjoying the custom route for features.

I was charged £53 for something I never agreed too.
I payed a 1 year subscription, about £17 to sort out my car and never used it since.
I am a Pensioner and can't afford that money, I HAVE INFORMED CARLY BUT HAD NO REPLY.
IF IT'S NOT SORTED I WILL POST ON EVERY MOTORING SITE I USE INCLUDING I.A.M
I FEEL CHEATED !!

We’re sorry that the £53 renewal came as such an unexpected charge, especially after you only intended to use Carly for your original one-year subscription. We also understand how frustrating it is to feel that you contacted us and did not receive a reply.
Carly is offered as an annual app license that renews unless automatic renewal is deactivated beforehand. Because we cannot review your license, payment, or support history publicly, we’re unable to provide a specific solution here on Trustpilot, but we do want your case to be checked carefully.
Please open a new ticket here: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960 and write “To Support Manager” in the ticket title or subject. Please do not share personal data publicly. If you already contacted us, you can mention your previous ticket details in the new request so the case can be reviewed properly.
Carly produced codes which don't exist
Carly produced codes which don't exist. Tried reporting problem but Carly support said if codes are given, then there is no fault. Scanned same vehicle with Autel and got specific code straight away and could perform repair. Very disappointed with Carly.

Thanks for your feedback. We understand multiple fault codes can feel overwhelming.
Our approach is to display all fault codes, including non-critical and historical ones, so car enthusiasts can get the full picture of their vehicle’s status. However, when codes are critical, we always make sure to clearly notify you.
This is a deliberate choice to give you as much detailed information as possible. We hope this helps you better understand the situation!

I tried to cancel the subscription just days after you charge me for a full year. You wouldn’t credit any of the price even though I hadn’t used the device in ~1 year.

We’re sorry that the renewal charge came as a frustration, especially since you had not used Carly for around a year and tried to cancel shortly after the new annual period started. We understand why you expected a partial credit in that situation.
Carly is offered as an annual app license that renews unless automatic renewal is deactivated before the renewal date. Once the renewed digital license period has started, refunds or partial credits are limited, even if the app or device has not been used recently. The renewal charge covers access to the Carly app license for the new annual period, not only active usage on specific days.
We understand that this policy may not match every customer’s expectations. Feedback like yours helps us keep improving how we explain renewal, cancellation, and refund conditions before the next license period begins.

Was great to start with on my BMW e90 for the first month and then would not read any of the modules.
Complete waste of time and money, have moved to a professional platform in Launch system.
Would not recommend.

Reply from Carly Solutions GmbH
We’re sorry that Carly worked well with your BMW E90 at first and then stopped reading the modules. We understand how frustrating that is, especially when the app no longer performs as expected after the initial use.
Module access can depend on several technical factors, including the vehicle’s control units, software status, adapter connection, app version, and communication conditions during diagnostics. If Carly was able to read modules at first and later stopped, this may indicate a technical issue that should be checked rather than a general lack of support for the vehicle.
Please contact our support team here: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960 with the details of what changed, when the issue started, and any error messages shown in the Carly app. This helps us review the diagnostic behavior for your BMW E90 and understand why the module reading stopped working.

Good evening. I have had an engine malfunction message in my Alfa Brera for some time now. A few days after receiving it, I plugged in the scanner. All the lights on the dashboard lit up, and immediately after the temperature control unit lit up, it went out. So the air conditioning and heater stopped working!! Upon inspection at a garage, it turned out fuse F39 was blown due to the Carly!! I no longer trust your device and dare not use it again!!

We’re sorry to hear about the issue with your Alfa Brera and the concern that occurred after using the Carly Scanner. We understand why this would make you hesitant to use the device again.

Thank you for your feedback. It helps us improve how we communicate Carly membership, license terms, and cancellation options.
Being honest here
Honestly, paying $120 per year doesn't seem justified if the service can't provide actionable solutions to vehicle problems, unless you have the smart mechanic option (which costs additional $$).
I can go to almost any auto parts store and have my vehicle scanned for trouble codes at no cost. If I still have to spend my own time researching those codes and figuring out the repair myself, I'm struggling to see the value in the subscription.
The real benefit should be helping users move beyond code reading and toward identifying likely causes, recommended repairs, and practical troubleshooting steps. Without that, it's difficult to justify the annual cost.

We’re sorry that the Carly App felt slow and frustrating to use, and that the paid license model did not meet your expectations.
Carly is offered as an annual app license that unlocks the digital functions in the Carly App. Without an active Carly license, only basic OBD standard functions are available, while manufacturer-specific diagnostics and advanced Carly functions are part of the digital license.
We understand that performance, pricing, and the difference between free and paid functions need to be clear and reliable for customers. Your feedback helps us improve both the app experience and how we communicate the license model.
Be careful!!!!
Carly device arrived, didn't work. Followed all instructions, still didn't work. Carly sent replacement, doesn't work again!!! Since then I have read lots of very bad reviews about Carly & their poor performance. Devices not working & money being taken after subscriptions are cancelled seem commonplace issues. Look carefully at alternatives before buying!!!

We’re sorry that both your original Carly Scanner and the replacement did not work as expected. We understand how frustrating that is, especially after following the instructions and still not being able to use Carly properly.
If two devices show the same issue, several factors may need to be checked, such as adapter connection, app setup, vehicle communication, account status, or whether the device is being recognized correctly. We also understand your concern after reading other negative reviews, including comments about renewals and cancellations.
Please contact our support team here: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960 and include what happened with both devices, any error messages shown in the Carly app, and the previous replacement details if available. Please do not share personal data publicly. This allows the issue with the scanner and your account to be reviewed in the right context.
