## Key experiences

### Turn every drive into a record worth revisiting.

Automatically collect distance, duration, speed and RPM for each trip, then review engine changes on a shared timeline. Export to CSV or Excel for deeper vehicle records.

- A searchable trip list with essential figures
- Trip detail with speed, RPM and export controls

### Read vehicle health and habits from three distinct angles.

Health reports cover battery and cooling; cost reports calculate fuel spend and efficient speed; behavior reports reveal acceleration and driving zones. Together they turn local history into practical guidance.

- Vehicle health trends for battery and cooling
- Fuel-cost analysis with the most efficient speed range
- Behavior analysis for acceleration and operating zones

### Go beyond the code to what the driver should do next.

Read confirmed and pending faults with symptoms, likely causes, severity and driveability guidance. Emissions readiness and a full code library complete the diagnostic flow.

- Fault diagnostics with severity and likely causes
- Emissions readiness across catalyst and sensor checks
- A complete diagnostic library searchable by code or symptom

### The driver remains the owner of every vehicle record.

Manage storage, deletion, themes and units directly. Trips and diagnostics stay on-device without an account or analytics server, while demo mode lets anyone explore before connecting an adapter.

- Settings for storage, units, themes and demo access

## Essential features

- **Live vehicle dashboard**: Monitor RPM, speed, coolant temperature, voltage and load across four purpose-built gauge styles.
- **Diagnostics in plain language**: Fault codes come with symptoms, likely causes, severity and practical driveability guidance.
- **Long-term driving insight**: Track fuel efficiency, idling cost, cold starts, battery trends and driving behavior using local trip data.

## Made for

- Drivers who want direct visibility into vehicle health
- Efficiency-minded drivers improving fuel habits
- Technicians and DIY owners working with codes and trends

## Privacy and notes

Trip and diagnostic data stays on the device without an account, and every analysis runs locally.
