Your car,
in plain words.
A warning light came on? Klaromo reads what your car knows about itself and explains it simply: is it serious, can I keep driving, how much will it cost.
Free · Android 8 and later · Requires a Bluetooth OBD2 adapter (€12 to €70), sold separately.
Three steps, no technical knowledge.
Works with every petrol car sold in Europe since 2001 and diesel since 2004 (OBD2 / EOBD standard).
Plug in the adapter
Into the diagnostic port under the steering wheel on the driver's side (sometimes behind a cover). Switch the ignition on.
Run a scan
Klaromo reads confirmed, pending and permanent error codes, the warning light and emissions tests, in seconds.
Understand and act
For each code: what it means, whether you can keep driving, common causes and what the repair may cost.
What you'll see on your phone.

Klaromo adapts to your adapter.
When it connects, Klaromo actually tests what your adapter can do (the name on the box is not enough) and offers everything it supports.

What Klaromo does, and doesn't do.
Klaromo
- Reads the car's real data, and shows it raw if you want to check
- Tells you honestly when your adapter or car can't do a reading
- Keeps everything on your phone: no account, no ads
Klaromo does not
- replace a mechanic: its explanations are indicative
- change your car's programming (no coding)
- repair anything by clearing a code: the light comes back if the fault is still there
