Gaugeo - OBD2 Dashboard

Gaugeo turns your phone into a live car dashboard. Plug an ELM327 Bluetooth OBD2 adapter into your car and watch your engine data in real time – free, with one small banner ad (never on the live dashboard).

LIVE GAUGES
• Speed, RPM, coolant temperature, engine load, throttle, intake air temperature, fuel level and more
• Clear analog-style gauges and a compact value list
• Fast refresh rate, built for the road

TROUBLE CODES
• Read stored and pending codes
• Plain-language descriptions
• Clear the check-engine light when you are ready

LOGGING
• Record a drive and export it as CSV
• Analyze later in a spreadsheet

DEMO MODE
• Try every screen without a car or adapter

PRIVATE
• Connects directly to your adapter over Bluetooth
• No account, no tracking, no vehicle data leaves your phone

WHAT YOU NEED
• An ELM327-compatible Bluetooth (Classic) OBD2 adapter, paired in your phone's Bluetooth settings
• A car with an OBD2 port (most cars since 2001 in the EU/2008 in the US)

Safety: do not operate the app while driving. Displayed values are informational and may differ from your car's own instruments. Clearing codes can erase stored vehicle data.

New look: a calm night-blue design that matches the icon, clearer gauges and smoother transitions. Text now fits cleanly at large font sizes in every language.
