SmartControl OBD2 Scanner

OBD2 diagnostics & live data via Bluetooth. Clear faults, monitor your car

SmartControl OBD2 Scanner

Ad-free car diagnostics, fuel logging and live-data coaching for drivers who care about efficiency and the planet.

Why SmartControl exists

I built this tool—first for myself, now for everyone—because numbers change behaviour.

When you see how each throttle press affects fuel, money and CO₂, you naturally drive smarter.

SmartControl turns raw OBD2 data into clear, actionable insight without drowning you in ads or gimmicks.

What you get for free

Read & clear trouble codes (DTC)—engine, transmission, OBD-II generic.

Live data dashboard: RPM, coolant, fuel trims, boost, battery, and more at up to 10 Hz.

Trip computer: distance, average speed, drive time, altitude.

Theme selector: day/night, large gauges for garage or bike handlebar.

Privacy first: all data stays on your phone—no account, no cloud.

Upgrade once, unlock everything

Feature Why it matters
