“A loose heat shield is more likely than internal engine damage. Check after the bike cools.”

From noise to signal

A better first listen.

WrenchEar combines vehicle-specific sound patterns with the context only you can provide, so the result is useful in the driveway and understandable at the repair shop.

Start where the sound starts.
01

Record the sound

Capture the rattle, knock, whine, or click right where it happens—cold start, idle, or under load.

02

Add the useful context

Guided questions narrow the field with details like vehicle, mileage, timing, and what changed recently.

03

Leave with a next step

Get a plain-English shortlist, confidence levels, practical checks, and a clear signal when to call a pro.

What you get back

Less jargon. More direction.

A shortlist is only useful when you know what it means and what to do next. WrenchEar keeps the explanation practical, honest, and easy to share.

Safety first

Know when listening is not enough.

WrenchEar is a practical first check, not a mechanical or safety diagnosis. If a sound comes with warning lights, smoke, fluid loss, loss of control, or feels unsafe, stop and get professional help.
