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.

We’re sorry that the coding functions did not work as expected and that the available code list felt too limited. We understand how frustrating it is to pay for Carly and then feel that the functions you wanted are not usable.
The available Carly functions depend on the vehicle brand, model, year, installed control units, and vehicle software. This means that some coding options may not be available, may behave differently, or may not be supported by a specific vehicle configuration.
We understand that these limitations need to be clear before purchase. Your feedback helps us improve how we communicate coding availability, vehicle compatibility, and technical restrictions.
it works smooth

The app is far too slow
The app is far too slow, takes forever to come up with the answer, waste of money, a £10 reader from eBay is a lot better!

Reply from Carly Solutions GmbH
We’re sorry that the Carly App felt too slow for you and did not meet your expectations. We understand how frustrating it is when a diagnostic process takes longer than expected, especially when you are comparing it with another reader.
The speed and available results can depend on the vehicle model, control units, connection stability, and the diagnostic function being used. Still, the experience should feel reliable and useful. If you would like us to check what may have affected the connection or reading time in your case, please contact us here: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960
Thank you for your feedback. It helps us improve the Carly App and the way diagnostic performance is communicated.

Reply from Carly Solutions GmbH
We’re sorry that you were charged after believing your subscription had already been cancelled. A cancelled subscription cannot be renewed by Carly, as there would no longer be authorization for a renewal. In cases like this, there may be another active Carly license connected to a different account, purchase, or subscription setup.
For privacy reasons, we cannot check or discuss payment or account details publicly on Trustpilot. Please contact us through our support form so we can review the subscription status, renewal date, and cancellation history for your case: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960
Thank you for raising this. We want to make sure the situation is checked carefully and clarified properly.

We’re sorry that Carly did not work as expected for you and that you feel the subscription was not worth the price. We understand how frustrating this is when you expected the product to help with your vehicle.
Carly combines the adapter with an annual app license, which unlocks the available Carly features. These features can depend on the vehicle brand, model, year, installed control units, and software version, so not every function is available for every vehicle configuration.

Overpriced, non-intuitive solution
The software interface is not intuitive at all, on a brand specific computer the mechanic read out additional almost 10 items directing us in a different direction. You have to pay a full year upfront and no chance to get any money back once you quit and not happy. Extremely disaapointed.

Reply from Carly Solutions GmbH
We’re sorry that the Carly App interface was not intuitive for you and that the diagnostic results did not match what you later received from a brand-specific workshop tool. We understand how disappointing that is, especially after paying for a full annual license.
Carly is an annual app license, and available diagnostic results can depend on the vehicle brand, model, year, installed control units, software version, and the diagnostic method used. A brand-specific workshop system may sometimes access additional manufacturer-level data that is not available in the same way through Carly.
If you believe the product did not work as expected in your case, please contact us so we can review the technical details and your license situation individually: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960
Thank you for your feedback. It helps us improve the Carly App experience and how we communicate diagnostic scope, license terms, and refund limitations.
The programming never works.

Reply from Carly Solutions GmbH
We’re sorry that the coding features did not work as expected for your vehicle. We understand how frustrating it is when you buy Carly for a specific feature and then cannot use it as planned.
Available Carly Features depend on the vehicle brand, model, year, installed control units, software version, and technical configuration. This means that a vehicle may be generally supported while individual coding features are not technically available for every variant.
Since we cannot check your vehicle details publicly, please contact our support team so they can review the specific coding feature and your vehicle configuration. Please do not share personal data here on Trustpilot.
Your feedback helps us make our compatibility and feature information clearer before purchase.

We’re sorry that Carly has not worked reliably for you. We understand how frustrating it is when the app or expected features do not behave as they should.
Available Carly Features can depend on the vehicle brand, model, year, installed control units, software version, and technical configuration. Because of this, some features may work differently depending on the specific vehicle setup.
Your feedback is important to us, as it helps us improve both product reliability and the way we explain feature availability and compatibility before purchase.

We’re sorry that Carly has not been able to read the computer on your 2006 Jeep Wrangler TJ, especially since the vehicle was listed as supported. Compatibility can depend on the vehicle’s installed control units, software, and technical configuration, but if support for this model was shown before purchase, we’d like to review it.

STAY WELL CLEAR
STAY WELL CLEAR
I paid for the top package with every car included, it doesn’t show codes that actually could detect a fault with your car engine, turbo etc. my car only showed a NOX sensor on Carly OBD but taking it to Volkswagen revealed the turbo was totalled. And the customisation doesn’t work either.
On top of that they do their best to hide a yearly subscription when you purchase it, no direct debit shows on an account with no warning they are going to charge another £104 annually and do not offer any sort of refund. I have used it maybe twice in the year I have had it and don’t plan to use it again go for a cheaper OBD reader that actually shows necessary codes. DO NOT BUY

Unprompted review
Reply from Carly Solutions GmbH
We’re sorry that Carly did not meet your expectations for diagnostics, customisation, and the annual app license. Carly can read fault codes reported by the vehicle’s control units, but available data and functions depend on the vehicle model, installed control units, and software. Carly is offered as an annual app license that renews unless automatic renewal is disabled beforehand, and activated digital licenses can only be refunded in limited cases. Your feedback helps us improve how we communicate diagnostic scope, feature availability, and renewal terms before purchase.
An excellent product
An excellent product, bought owing to problems with my daughter's BMW E92 which it resolved, but also offers a great many other features that I was not expecting, such s coding to open/close features of the car that I would have thought only available to a BMW Authorised Dealer

Although a potentially good product
Although a potentially good product, the whole subscription service is very sales orientated and your OBD becomes a brick without it. Seems everything now is subscription based and you never actually own products anymore

I blew an engine on 2015 Toyota Avalon, Carly gave no warning. Also the tranny went on the family's 2020 Toyota Corolla again without a warning from Carly.

We’re very sorry to hear what happened with your vehicles. We understand how upsetting it is when serious issues occur without any warning. There can be many reasons why this happens, and not every mechanical problem will show clear electronic signs that a diagnostic app can detect in advance. Still, we understand your point and regret that Carly did not give you the reassurance you expected. We’re sorry to see you go.
