Overview
Smart Car Companion App is a prototype that pairs with a Bluetooth OBD-II adapter to give drivers real-time diagnostics, trip history, fuel efficiency tracking, and proactive maintenance reminders in a single mobile experience.
This is a product prototype created for portfolio demonstration — not a verified client engagement.
The Challenge
Everyday drivers often lack visibility into vehicle health and rely on dashboard warning lights that give little context, leading to reactive rather than preventive maintenance.
Concept Solution
We built a companion app that connects via Bluetooth LE to an OBD-II adapter, translating raw diagnostic codes into plain-language insights, trip summaries, and maintenance scheduling reminders.
