The product does not work, there is zero support, it doesn't have basic coding features as advertised. My device stopped reading the ECU (it would only read live data). Once you subscribe there's no easy way to cancel, no notification of renewal and once you're auto-billed you'll hear "too bad, German law allows us to charge you for a full year." Even after I told them my device did not work they still decided the refused to refund my purchase. Stay away.

pretty good, just doesn't seem to have much in actuators. couldn't turn some things on to test them as in reverse lights on my 2006 bmw 325i. also I should be able to unbrick certain things in the CPU... as in reverse lights. if something is activated 50 times and it did not work, then that feature is disabled. some scanners as in one that starts with lau....which is pretty cheap can disable that feature.

Total scam, do not buy this garbage. I learned shortly after ordering that the battery registration functionality for my model straight up does not work. Only a few hours after placing my order I contacted support to have my order cancelled. They clearly have an automated reply bot that just rejects any requests for a refund or order cancellation. I am now having to work with my credit card company to do a chargeback because Carly won't hire a human to do real customer support. Total garbage.

Straight out of the box it will not connect to any vehicle. I have tried everything the app and Google says. I submitted multiple support tickets with zero response. No refund and absolutely no real response from the company. It also takes an insane amount of effort to cancel your subscription. If it doesn't get canceled they will bill you every year! do not buy this product!

The app was ok for my Bimmer - some coding possible. Good for someone like me with limited experience. Useless for my Ford Edge. Bought the full version, and I get to download some reports. Wow. Reports my mechanic would never need or use. Useless to me now. Forgot about the subscription. Renewed this morning because they don't send a reminder. Requested a refund 10 minutes later. Of course, got the old "You agreed to No Refund policy when you purchased - Sorry". No more business from me.

Bought this with a subscription so I could tweak some stuff with my headlights and DRLs as well as a few other things. Worked well. I ended up buying aftermarket headlights and wanted to reverse what I did with the DRLs, so I fired up Carly again and found out that none of the same coding options were there. I had two really lame things I could modify and that's it, so I was dead in the water with my headlights. Carly support was of no help and suggested that my car wasn't compatible. 🙄

Was a subscriber for 2 years. This app just feels like a scam. Maybe it was great once. Older reviews talk about how great it was. But now the subscription model cost is too high when you can buy other scan tools for the same price. And those are one time cost . Not yearly. I had to email them a request with a copy of my original invoice in order to stop the auto renewal. No way to do it online. Or to remove any payment or personal information.

Requires subscription. Bought the Pro version but still can't upgrade to the latest. Good for Mechanic but for individuals subscription is expensive. Have GPA number but won't accept it. Thanks for responding. While I understand your point, I believe the subscription amount is too highe if you do not use often. I don't mind paying $30 annually even if I don't use it often, but $82 is a bit much. Discount for those who have GPA.3380-6038-....that are not working?? Just a thought. Added STAR

Downgrading from 2 to 1 star. They couldn't support my E92. Fine they offered to add smart mechanic. I agreed to that. They said they have added it. Yesterday I tried using smart mechanic for the first time and it is not added to my profile. I reached out to them and they asked me to file one form. I submitted that form and then the said to submit another form. I submitted that form and they asked to submit a different form. And then they closed that ticket. Carly = forms galore.

Purchased in May of 18 thinking it was a one time deal, bought the adapters and everything for all of my cars, used it, and put away. Now that I need it once more a year down the road, I need to renew a subscription? I literally used the ap for less than a week getting codes and resetting stuff, and that's apparently worth a yearly subscription? Now to program a battery I need to pay another year? This is a rip-off to a here and there user like me....

Powerful app in that it can do a lot of coding that others can't. However, compared to other solutions which also use the model of wireless adapter and mobile app, Carly's connection between car and adapter is fragile and finicky. Further, the user interface is much worse than its main competitor, and it's more expensive. I bought this thinking that after years of development, the GUI would have improved, but no. Cannot function in Portrait mode. Gives poor descriptions of codes. Can't recommend

Fails 90% of the time. It will connect to my OBII adapter and then will not move past the 3rd part of the connection process. The first time took 20 minutes with no results. Then 30 minutes with no results. Then 10 minutes and it connected. When it finally did connect it lost connection when I tried register my car battery (one of their selling features). Then, for some inexplicable reason, it made me go through the connection process again!!! This app is terrible. Get bimmergeeks protool

So this app needs a subscription to unlock all the features. Paid for the year so you already got my money. I was using a USB cable to read error codes and do coding, but this new update looks like it broke that. Needed to check something last night, but it gets stuck looking for a Bluetooth device when connecting. I guess this update is to get people to spend more money. So even though I've paid, I can't really use the app anymore.

It mostly works, but they promise a lot in their trial and marketing, then you find out what really works for your model. Worst is that they're a really shady company to deal with. They give no warning for impending renewals or price increases, and they make it really, really hard to cancel. For BMW Buy Protools instead, it does a ton more, it's a one time purchase, support is great (and based in the US).

This app used to be great, before the "subscription" only days. Saved me a few times with a mini Cooper. Now it is nothing more than a heaping pile of garbage. Can't connect via USB and otg adapter which worked great with the old app. No thanks, I don't code over an unreliable wireless connection. The interface is made for someone who knows nothing about cars, who most likely wouldn't use an app like this. Option to change to an advanced interface? Nope.

Great tool. Not exactly intuitive though, and there's a few pay-walls to get additional features - especially for BMW/MINI. Considering that it is cheaper than paying a BMW mechanic to do some of these things, it's worth it - but not the subscription service in my opinion. I already paid for the BMW features - I shouldn't have to also pay for the additional features in a subscription on top of that. Seems very "nickle & dimey"

The app used to be one of the best options out there... Not perfect but worth spending money on. Now you pay decent money and STILL get begged for even more money. "Remember how we gave you code descriptions before? Not anymore!! Now you have to pay even more!" Those are tricks free apps pull... That's unacceptable after I've already dumped $60+ on a one year subscription. Interface has continually gotten worse over the years as well. More and more layers to do simple things.

Overall everything looks great, however I don't see how this app/adapter system can fit a subscription model. Lite version is useless. Request to work out some other options without the subscription was returned like "nope, you need to pay subscription". So, I'm going to return it and will end up not paying anything at all, though I'm not sure how that's better for the business... Also, people who need money will work with you, so... Think for yourself, guys. I personally am very disappointed.

Generally works OK. Yes, need to buy the adapter and the full version, but that compares favorably to one shop visit. Support is really poor -- consists of automated responses based on best matches to your question. Really poor, but I guess better than some very amateurish apps. Interface is all brand new... again... and now has more pointless fluff. not an improvement! Lets you log live data but there's no way to view the log -- it's encrypted. I guess the "save log" feature is either there for future use or just to make you mad. Shows error codes in a non-standard format, so makes it hard to google for answers. All that said, it's a cost effective way to get clues as to the source of the problem, much more convenient than a laptop/cable, and I get the impression they're growing, so one can hope they'll eventually actually improve the product vs just trying to grab market by adding compatibility with other brands?

Not a happy customer. This works ok for basic obdII functions but past that it's frustrating. It takes forever to connect and actually complete a scan, especially long to get into coding. Once in coding there isn't much to do, and some of it doesn't even work. Mainly bought carly to try to get rid of daytime running lights, on the first 2 tries I turned them off in carly...and nothing happened. So I updated the app....and now I don't even have the option anymore...waste of $$
