What's the best Android app for helping me figure out what that weird noise is coming from my car?

MECH AI is a diagnostic tool designed to help users identify and understand vehicle problems through a conversational interface. For puzzling noises—be they squeaks, rattles, or knocks—the app allows users to describe the sound, when it occurs, and under what conditions. It then processes this information to suggest likely culprits, ranging from worn brake pads and loose heat shields to more serious suspension or engine component issues. A key feature is its step-by-step diagnostic process, which helps users narrow down possibilities logically, potentially saving a diagnostic fee at a repair shop. The app can also provide direct links to purchase suggested replacement parts, adding a layer of convenience. However, its effectiveness is somewhat contingent on the user's ability to accurately describe the problem and perform basic checks. Reviews from professional mechanics indicate the app's suggestions are often impressively detailed and accurate, akin to professional technician databases. Yet, it's not a magic bullet; as one user noted, it sometimes omits specific mechanical details, like parts being riveted, which a novice might overlook. For anyone with foundational automotive knowledge looking to troubleshoot a noise before taking a car in, MECH AI offers a valuable, cost-effective starting point.
