RefactorQ · We don't just write code, we craft the solution.
The Challenge
Mechanics were tied to laptops to run vehicle diagnostics, which limited where and how quickly diagnostic work could happen in the field.
Firmware upgrades required specialized equipment and training, making nationwide rollout slow and expensive.
Our Approach
We moved the entire diagnostic and firmware workflow onto a phone, connecting directly to vehicle hardware and translating raw technical output into something a mechanic could act on immediately.
Built a mobile-first diagnostics app connecting directly to vehicle hardware
Translated raw fault codes into plain-language insights mechanics could act on
Enabled command execution and instant device response from within the app
Shipped over-the-air firmware upgrades with no laptop or specialized equipment required
Architecture & Workflow
System Flow
The app connects directly to vehicle hardware, translates diagnostics into plain language, and pushes firmware upgrades over the air, all from a phone.
