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.

We’re sorry you feel our replies were too automated—that’s not what we want to offer. We use some automated responses to provide instant help and reduce waiting times, but we also have trained agents ready to assist you in 8 languages, 7 days a week. We’re always working to improve our support process, and your feedback helps us a lot. Thank you!

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!

We’re surprised to hear that, as we are proud of assisting 7 days/week. If a message is sent to a no-reply email, this could happen. Please reach out to our support here: https://support.mycarly.com/hc/en-us/requests/new?ticket_form_id=360000444960. Include "To Support Manager" in the title, so we can prioritize you. Thank you for your time!

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.

Thank you for your feedback. When it comes to the app license as a digital content, you acquire it for use during a certain period of time, and our terms and conditions explains that it is non-refundable after confirming the purchase. License rental applies to different German law from a normal product purchase. We appreciate your understanding.
