User reviews

The app every mechanic needs

Super easy to use, really helpful. Have been using it on every job for the past couple of weeks now and can’t get over how easy it makes the job.

Brilliant app

Genuinely impressed with this. The layout is clean, it’s really quick to use, and the accuracy is better than I expected. What stands out most is that it explains why it’s suggesting things instead of just listing faults, which makes a big difference and actually helps you understand what’s going on. It already feels like a solid, reliable tool to have on hand when diagnosing issues.
