### 2/5 — Nicht wirklich brauchbar.

*2026-08-20*

Hab es mir gekauft da ich mir ein Mercedes gekauft hatte und denn prüfen wollte, es wurden paar Fehler angezeigt aber nur mit Fehler Code ohne Bedeutung also selbst weiter Sachen. Dann hab ich es noch mal mit Profile Diagnose auslesen lassen und da waren sehr viel mehr Fehler vorhanden als das 4 fache mehr also kann man sich nicht mal dadrauf verlassen und vor allem nicht bei Gebraucht Wagen Kauf. War die tage unterwegs und 2 Pannenfahrzeuge angetroffen, da ich denn Adapter im Auto liegen hatte, schnell Abo reaktiviert und angeschlossen, beim Auto wurden denke alle Fehlermeldungen angezeigt die das Auto anzeigen kann, aber die Diagnose hat 0 Fehler gefunden und Auto im Top Zustand angezeigt, beim zweiten Fahrzeug nur 2 Fehler Bremslicht und so, aber die anderen kritischen Fehler wurden nicht angezeigt wie „Störung Bremskraftverstärker“ wurden nicht gefunden/Angezeigt. Ich hab es jetzt bei glaub ich 10 Fahrzeugen getestet und bei keinem hat es alle Fehler angezeigt, nicht mal bei VAG Fahrzeugen. Dann auch Verbindungsabbrüche, aber damit hätte ich leben können wenn es wenigstens alle Fehler finden würde, auch wenn nur denn Fehlercode.
Also muss ich leider Sagen es bei meinen Versuchen total unbrauchbar war und ich es für einen Gebrauchtwagen Kauf auf garkeinen Fall verwenden würde, denn wenn es keine oder nur Defekte Lampen Anzeigt würde es denn Fahrzeug Zustand verfälschen und man würde dadurch nicht genauer hinschauen.
Die zwei Sterne gebe ich wegen der eigentlich Idee, es wär schon Cool wenn man so ein Gerät einfach im Auto liegen haben konnte und im Notfall es einfach nutzen könnte.

**Developer response:** Es tut uns leid, dass Ihre Erfahrung nicht Ihren Erwartungen entsprochen hat und Ihnen nicht den erhofften Mehrwert geboten hat. Carly ist bestrebt, auf unserer Website so viele Informationen wie möglich bereitzustellen, damit Kunden klare Erwartungen entwickeln können.
Gleichzeitig verstehen wir, dass manche vielleicht andere Produkte bevorzugen, die ihren Bedürfnissen besser entsprechen. Wir wissen die Chance, die Sie Carly gegeben haben, sehr zu schätzen und bedauern, dass Sie uns verlassen.

### 1/5 — Lousy support

*2026-08-16*

After countless back and forth and no resolution, a poor review here, the developer responded asking that I open a ticket to the support manager. I open yet another ticket and ……NOTHING. Their responses here are empty promises just like the product

**Developer response:** We’re sorry that you had a frustrating experience. It seems there might have been a misunderstanding. You can also reach 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 it. We're confident we can find a solution together.

### 1/5 — Deliberately charge you bank £60 with your permission

*2026-08-15, version 41.26.081313*

Worst company ever don’t use them waste of money this is a yearly subscription to use their devices on specific vehicles only not all vehicles

### 1/5 — False advertising!

*2026-08-12*

MyCarly should be removed from the App Store for their deceptive business practices and false advertising. They cannot code any of the features they advertise for BMW G05 and provide zero support. Buy a BimmerCode or anyone else

### 1/5 — Update log

*2026-08-07, version 41.26.080516*

Can you be more precise what your updating, you have this update log from 1980s man last time ever I’m buying your product again.

### 1/5 — Scam

*2026-07-25, version 41.26.072213*

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.

### 1/5 — Warning beware the auto renewal

*2026-07-17, version 41.26.070812*

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

### 1/5 — Be warned

*2026-07-17, version 41.26.070812*

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...

### 3/5 — Difficult to cancel subscription

*2026-07-15, version 41.26.070812*

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.

### 1/5 — Scam Warning

*2026-07-08, version 41.26.070218*

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

THIS IS A SCAM COMPANY!!!
