Carly has two parts: an adapter and an app
Before we talk prices, it helps to understand the structure. Carly is not a one-time purchase — but it’s also not the endless subscription trap some reviews make it out to be. Here’s how it actually works:
- The Carly adapter is a physical OBD2 Bluetooth device you plug into your car. One-time purchase. Yours to keep forever.
- The Carly app is a subscription that unlocks diagnostic features for your specific car brand. The price depends on your car.
That’s it. Two things. Let’s break each one down.
The adapter: one-time cost, works on any car
The Carly OBD2 adapter connects to the OBD port found in virtually every car made after 2001. It pairs with the Carly app on your smartphone via Bluetooth — no wires, no extra hardware.
Price: €64.80 One-time · Works with any OBD2 car · Keeps working even if you cancel the subscription
Even if you later decide the subscription isn’t for you, the adapter doesn’t become a paperweight. You can still use it to read basic fault codes on any OBD2 car without a paid subscription.
The subscription: why it varies by car
This is where most of the confusion comes from — and the reason some reviewers cry “trap.” The subscription price varies depending on your car’s make and model. Here’s why that’s actually fair:
Different car manufacturers use different diagnostic protocols, and the depth of access Carly can achieve varies significantly. For a BMW, Carly can read data from almost every system in the car. For a Renault, the access is more limited. It wouldn’t make sense to charge the same price for both.
| Your car brand | What’s available in the app |
|---|---|
| BMW, Mercedes-Benz, Audi, VW, Porsche | Full diagnostics, deep coding, service resets, used car check |
| Toyota, Ford, Renault, Fiat, and others | Core diagnostics, fault codes, live data |
| All other OBD2 cars (post-2001) | Basic fault reading and live data |

Basic vs. Premium: what’s the difference?
Within each car brand, Carly typically offers two subscription tiers:
| Feature | Basic | Premium |
|---|---|---|
| Read & clear fault codes (all systems) | ✔ | ✔ |
| Live data monitoring | ✔ | ✔ |
| Service reset | ✔ | ✔ |
| Deep diagnostics (ABS, airbags, gearbox…) | ✘ | ✔ |
| Car coding (unlock hidden features) | ✘ | ✔ |
| Used car check (full fault history) | ✘ | ✔ |
| Smart Mechanic (AI repair guidance) | ✘ | ✔ |
Not all features are available for all car brands. The compatibility checker at checkout will show you exactly what’s unlocked for your specific vehicle before you pay anything.
Is the subscription worth it? Here’s the math
The most common objection is: “I don’t want to pay every year for something I might not use much.” That’s fair. But consider the alternative:
| A standard dealership diagnostic: $80–150 per visit. Carly: unlimited diagnostics, from your phone, in your driveway — for a fraction of that cost per year. |
Beyond cost: knowing why your check engine light is on before driving to the dealership means you can’t be quoted for problems that don’t exist. That alone has saved many Carly users hundreds of dollars.
And to address the “trap” concern directly:
- You can cancel anytime — no lock-in period
- The adapter stays yours whether you subscribe or not
- There’s a free trial so you can test the app before committing
Frequently asked questions
Do I need the adapter to use the Carly app?
Yes. The adapter is the physical bridge between your car and the app. Without it, the app can’t communicate with your vehicle.
Can I use the same adapter if I buy a different car?
Yes. The adapter is universal and works on any OBD2 car. If you switch brands, just update your subscription to match your new car.
What happens to the adapter if I cancel?
It stays yours. You can still use it to read basic fault codes on any OBD2 vehicle without an active subscription.
Is there a free trial?
Yes. You can pair the adapter and explore a limited set of features before purchasing a subscription. No credit card required for the trial.
Does Carly work with my car?
Carly works with any car made after 2001 with a standard OBD2 port. Feature availability varies by brand. → [Check compatibility at mycarly.com/pricing/]
| Bottom line:Carly is not a trap. It’s an adapter you own plus a subscription that costs less than one dealership visit. If you drive a European car brand, the feature set is deep enough to pay for itself quickly. If you drive something else, the basic tier still gives you the ability to diagnose your own car — something dealerships charge $80+ to do. |
