See everything the app does

Live data

RPM, temperature, load, oxygen sensors and battery in real time, with a Bluetooth or Wi-Fi OBD2 adapter.

Trip history

Every trip with route, engine data and analysis, kept in your account on our servers.

No internet, no loss

Readings are saved on the phone and upload to your account when the connection is back.

One car, several drivers

Invite whoever drives the car. Trips belong to the car, with the name of who drove.

Standalone ECUs

Reads straight from Speeduino and MegaSquirt: AFR, lambda, boost, injector duty and knock count.

Artificial intelligence

AI that explains

The AI analyzes the car and shows the evidence behind each finding.

See the AI page
  • Connect the AI you already use: Claude, Cursor, VS Code or Gemini.
  • It follows the car live and analyzes the whole trip.
  • Every finding comes with the evidence: the data that led to the conclusion.
