Record ~50 seconds of your engine and EngineEar AI tells you what's likely going on — mechanical causes, urgency, and what to check before the workshop. Wear evaluation: does your engine sound its age? The AI compares its acoustic fingerprint to what a car of your make, year and mileage should sound like. Your garage stays free: multiple vehicles, fuel log, maintenance history, cost stats, backup and restore. Only AI analyses are subscription-based. 21 languages.
