Software and hardware, designed together.
Today OBDLab has two product lines that work as one system: apps that run on your phone and devices that connect to your car. More diagnostic tools are on the way.
Apps
Diagnostics and performance apps for iPhone and Android. They work with UstaOBD and with most ELM327-compatible adapters.
Devices
OBD2 adapters we design, program and test ourselves, built to get the most out of the Usta apps.
More ways to see inside your car.
Planned
- 01 Fluid quality tester One handheld tool to check engine oil, transmission fluid and brake fluid.
- 02 Professional ECU tools Deep ECU diagnostics and testing equipment for workshops and technicians.
From your car's port to your phone.
A Usta device plugs into the OBD2 port, reads your car's control modules and sends the data over Bluetooth to whichever Usta app you open.
OBD2 port
The 16-pin port under the dashboard. Through it, your car's control modules report faults and live data.
- Engine
- Gearbox
- ABS
- Airbag
- Battery
Usta devices
Our adapters read the car and send the data to your phone.
Usta apps
Turn the data into answers on iPhone and Android.
Tested together
Every app release is tested on our own hardware, so the connection holds up on real cars.
Updated together
Device firmware updates arrive through the app. Your adapter keeps improving after you buy it.
One team to ask
The people who write the app also design the device, so support has the full picture.
