Written by the company

Carly — OBD2 car scanner Founded in 2014 in Munich, Germany, Carly is an automotive tech company that connects drivers with the information hidden inside their cars. Carly provides simple solutions throughout the lifecycle of car ownership, delivering peace of mind and empowering you to save time and money. Our mission is to be a reliable companion for drivers that delivers powerful data and valuable insights. Unleash your inner car hero with Carly! The Carly OBD2 Diagnostic Scanner was named 'Runner Up for Tech Product of the Year ' at the prestigious Parker's Product Awards. 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. A pocket-sized catalyst for preventative maintenance, but a couple of small quirks in the app stop it from being perfect."

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 Carly app was confusing and difficult to understand. We appreciate your feedback and are continuously working to make the experience clearer and more intuitive.

Had to buy another ODB2 device

Had to buy another ODB2 device, 2nd one from Carly and the 2nd gen did not work. Not user friendly at all. Hard to tell what is wrong or what the check engine light is referring to in the app. Previous app and reader were easy and simple to use.

Auto renews without notice!

Honestly not worth the money the app is mediocre and it’s expensive for what it is.

As noted by many other customers (both here and on numerous reviews elsewhere) the auto renewal process is pretty unscrupulous. They know full well they’ll get loads in from auto renewal a year later so don’t even have the courtesy of reminding you - they’ll just take another £100+ from your account. Such a trap and let’s be honest, it’s just a legal scam.

Save your money and avoid the auto renewal trap.

Hi Alex, we understand why an unexpected renewal charge and the lack of a reminder would be frustrating. Carly operates lawfully, and the annual license and renewal terms are displayed during purchase, though we recognize that this information must be as clear as possible. The Carly app license can be used as often as needed throughout the year, and license revenue supports ongoing improvements to Carly software. We’re sorry the app and its value did not meet your expectations, and we appreciate your feedback about renewal communication.

More selectiveness in error messages to be added

Several error codes are collected when reading the OBD. From the car dealer I learned that the OBD always generates error codes, but that these are only serious if a warning light flashes on and/or the message returns. The OBD keeps a history of messages so these may be irrelevant or solved. The software should be more selective in the generation of error messages and trying to sell all kinds of other modules

Great Information - so far so good

Great Information so far , was able to address one issue and clear it ...with some worthwhile elbow grease.
One irritation is that the app locks up when running a scan on some specifics such as audio equipment …
Another problem that has come to light after purchasing is the subscription model , not made clear initially and whilst I have had some value already , I would expect some great leaps forward in both diagnosis and remediation features to stick with it .

Rip off .

It’s basically a scam. It works really well to start with then stops working while they try to squeeze you into paying high subscription fees. I have thrown mine away and bought a really good subscription free replacement. The Trustpilot reviews , the review scores and the fact YouTubers have stopped recommending them tells you all you need to know.

Hi David, we’re sorry Carly did not continue to meet your expectations. The Carly Scanner includes Carly Basic Features, while many advanced features require an annual Carly app license. That license can be used as often as needed throughout the year, and its revenue funds ongoing improvements to Carly software. Carly operates lawfully, and we take your concerns about the product experience and pricing seriously.

It is a subscription

It is a subscription, but they just don't tell you. The support chat just keeps answering how transparent they are, but wont give you any link to terms and conditions and they are not to be found on their website.

We’re sorry the annual Carly app license and its renewal terms were not clear enough, and that the Support chat did not provide the requested link. The license renews automatically unless canceled, as explained in our Terms and Conditions, which are available here: https://www.mycarly.com/company/terms-and-conditions/ We take your feedback about making this information easier to find seriously.

Worst scanner & even worse customer service

Worst scanner you can waste your money on. Bought for a Tesla. Came up with tons of fake codes that even a Tesla technician said aren't real codes. Then they automatically took £55 from my account a year later. I didn't sign up to a recurring payment. I wrote to Carly the day after they took it & asked for a refund as the scanner is useless. They refused. Disgusting customer service & useless product! Avoid at all costs!

Hi Shaz, we’re sorry the diagnostic results did not match the Tesla technician’s assessment and that the renewal and Support response added to your frustration. The Carly app license is annual, with its renewal terms shown during purchase, but we regret that this was not clear to you. We understand how disappointing the refusal of your refund request was and take your feedback about the fault codes, license information, and customer service seriously.
