Scam

I am extremely disappointed with this situation. I requested a refund for the charge of $261.47, but my request was rejected. I believe I have been unfairly charged and I feel that I have been misled regarding this subscription renewal.

I was not aware that this subscription would renew automatically, and I did not intend to continue using this service. Being charged $261.47 without clearly understanding that this was an annual renewal has caused me financial loss.

I believe this situation has been handled unfairly, and I am requesting a proper review of my refund request. I ask Apple to investigate this matter and reconsider the refund decision.

Warning beware the auto renewal

Normally never leave reviews but I have just been stung with the poor customer service and auto renewal scam this company runs.

Don’t bother unless you want to be paying money every year without a chance to get out of this product.

You have been warned

Be warned

If this product does not work, there will be no refund at ALL... There is no way to contact them, other than automated response.. Also this is a subscription.. You will be charged every year... Please buy a cheaper device that work, as Carly is a brand that cannot be trusted & is only after your money...

Update: Amazing that Carly seem to think not answering your questions is acceptable, as long as they reply to them even if they do not answer the question asked.. Looked all over the internet and seems with carly, if the product does not work... Then the answer is tough luck mate... We do not do refunds regardless.. Unless anyone can prove me wrong...

Difficult to cancel subscription

This company uses dirty practices to make it difficult as possible to cancel bloated overpriced subscriptions. You don’t get notifications or receipts. They don’t even add new features (for older cars, idk about new ones), what the heck are we paying for? Avoid!!!

Edit: they did the right thing and refunded me.

Scam Warning

This company will charge you $116.88 for sone fake yearly subscription years after you bought the device.

THIS IS A SCAM COMPANY!!!

Auto renew default to on

Thought the app was alright for coding and diagnostic, however I found the information was very limited with any of the codes. For you to understand the codes in more depth, you’d need to pay extra once more! moved to Carista as had a better experience. Out of the blue, another annual payment gets made, even after cancelling the transaction from my back they have still taken the money out and shock horror “no refunds”. They state it needs to be cancelled 30 days before billing.

Completely lost all respect for this company, wouldn’t recommend at all. Would recommend ODBeleven, Carista or even taking your car to your local garage rather than using this company.

Seriously ?

I am sat in my 2029 Mercedes e class with the EML light on. I plug in the Carly unit - immediately the car complains about reduced Command functionality but I press on. Wait for the Carly unit to update as I haven’t used it for a while and then I run the diagnostics - all sytems are green ! How can this be right when the car is clearly displaying an issue.

It would be nice to add ECO stop,start kill

Please add the ECO reflash to kill the start stop engine button

The obd full package all cars

It is the most rubbish thing ever what a scam takes the piss and don’t work on any of my cars I got Audi bmw merc non it works on I spent £230 what a joke scanner was 100 and then a subscription that wasn’t told to me that u have to buy for it to do everything don’t buy trust me better out there

Absolutely useless customer support!!!

Used it for a couple of months last year and canceled the subscription in the app store and the app, went bimmercode/bimmerlink as was more usefull to me, i dont understand how their licence works but it charged me trough apple pay for 2025 and then 2 years in my pay pall 2024 and 2025 and apparently you have to manually cancel the auto renewal in there as well as i got billed 3rd year licence a couple of days ago and support is not helpfull saying there are no refunds even the am not using their service and will not be using it for the current year i got billed.
Surely you should be able to refund up to 14 days if not happy with their service or if it doesn’t work for you.
Absolute scam!!!

Don’t waste your money

Works when it wants to - hasn’t got 2 of my vehicles on the system. Very clunky software

Poor

Bought for bmw f40 to code out stop start, the car has 5 ecu,s it can only read 3 so cannot disable stop start, tried it on my mk7 transit van and I cannot code anything on it, looked on previous updates of the app in the App Store and it’s all vw Audi Skoda every time it updates. Very disappointed with the product

ODB Scanner broke again

Why does this keep breaking every other software update.

Carly OBD2

I’ve paid all the money to Carly and it doesn’t work, I have speakon to Carly customer service with no luck, beware a complete waste of bees and honey.

Nope.

Terrible app, terrible software. Slow to connect, does absolutely nothing of use.

The most inexpensive coding/scanning tool out there

This is my second one. Got rid of the first one because I didn’t see being able to by another BMW right away. With that being said. I love this scanner. Coding is easy, the options are listed as to what it does per item. It saves coding options in order to go back if need be. Codes are descriptive so if you’re mechanically inclined it even more worth it. If you have multiple vehicles you can use it on them also. You can also use it for a future purchase to scan. This is definitely a good buy that won’t break the bank.

False Advertising - Waste of Money

I purchased through their website for $99.99 with free obd2 adaptor, nowhere did it say annual subscription. The app works, but disconnects frequently and is very limited in what it can actually do. It can’t do all they advertise, hence the title. They’ll tell you it’s vehicle dependent. They’ll upsell you on features you thought were included as well.

There are two other apps that can perform more for less money, and they’ve perpetual licenses.

Why does it cost so much???

I almost bought this with the “free” dongle offer, but then I realized it was a yearly subscription to keep using it which is ridiculous since you don’t add anything over that time!
Crazy ripoff
AND
App claims to show you what it can do before you pay BUT all I get is a stupid notification
“Information
Congratulations, this function is compatible with your car. For connecting your car finally with Carly, you'll need a Carly scanner.
Nevertheless, we want to show you different examples to gain a first impression of this feature. Have Fun!”
But then it doesn’t show anything!!!
Scam

Response from developer

Thanks for the feedback. Most features and previews are unlocked with the annual license, which is explained in advance. Without an active license and scanner, the app can only show limited examples, not full functionality. Availability also depends on the selected model and year. We appreciate the suggestion to improve previews.

Predatory and useless

They make it as difficult as possible to cancel your account. I didn’t even realise i still had one till suddenly i got a message from my bank saying 90euro was taken. It gets even more ridiculous when you realise that if you have a car that doesn’t have that many screens the device can do the equivalent of a 35€ diagnostic tool on amazon (without a subscription)

Game changer

Everyone who likes their car to be in best condition should have this tool. Really is ideal for home repairs and identifying faults and repairs before taking your car to a garage.
