About this app

Hear what your mechanic hears. EngineEar AI uses artificial intelligence to analyse engine sounds recorded with your smartphone — and gives you a full car-care toolkit: engine diagnostics, service reminders, fuel tracking and a free digital driver's logbook for tax.

Record your engine for around 50 seconds (30 s idle + 20 s revs — Guided Mode), or record freely up to 90 seconds. The AI returns a structured result: possible mechanical causes ranked by likelihood, an urgency level (Low / Moderate / High / Critical), recommended checks, wear evaluation and a confidence indicator.

NO OBD DONGLE REQUIRED — your built-in microphone is all you need.

AI ENGINE SOUND ANALYSIS

- Works on any car, SUV, truck, van or motorbike
- AI diagnosis delivered within seconds after recording

- No account, no login — completely anonymous
- Audio deleted immediately after analysis, GDPR compliant

WEAR EVALUATION — MORE THAN DEFECT DETECTION

The app compares your engine's acoustic signature to what a car of your make, year and mileage should sound like. If a 5-year-old, 50,000 km car already sounds like a 200,000 km workhorse, you want to know — especially before buying a used car.

MY GARAGE — YOUR CAR, FULLY MANAGED

- Fuel Log: every refuel with consumption (L/100km or mpg), average price and lifetime totals
- Maintenance Schedule + Reminders: 8 standard items per vehicle plus your own (incl. one-time events). State per item (OK / Due Soon / Overdue) with daily notifications
- Service History: every "Mark done" creates an editable log entry
