A companion mobile app that plugs directly into your vehicle's brain. Connect any standard ELM327 OBD2 adapter over WiFi or Bluetooth, read live engine data, pull and clear diagnostic trouble codes, and sync everything to your DDPC garage automatically.
The Problem
Vehicle diagnostics shouldn't require a $500 scan tool or a trip to the dealer. Every car made after 1996 speaks OBD2 — a $20 adapter and the right app can read the same data. But existing apps are either too technical for normal people or too dumbed down for enthusiasts. And none of them connect to your actual vehicle management system.
DDPC Connect bridges the gap — real diagnostics, real data, synced to the garage you already use.
What It Does
Turn your phone into a diagnostic tool that speaks the same language as your garage.
Live Diagnostics
Real-time engine data: RPM, coolant temp, throttle position, fuel trims, O2 sensors. Rendered in clean gauges, not hex codes.
DTC Management
Read and clear check engine codes with human-readable descriptions. Know what’s wrong before the shop tells you, and clear codes after you fix it.
Dual Connection
WiFi TCP and Bluetooth Low Energy support. Works with any standard ELM327 adapter regardless of connection type.
Garage Sync
Diagnostic sessions sync to your DDPC vehicle profile. Build a timeline of what your car reported, when, and what you did about it.
Offline Capable
Core diagnostics work without internet. Data queues locally and syncs when you’re back online. The parking garage doesn’t have WiFi, and that’s fine.
Cross-Platform
Built with Expo and React Native. iOS and Android from one codebase.
Under the Hood
DDPC Connect is a React Native app built with Expo, targeting both iOS and Android from a single TypeScript codebase. It communicates with ELM327 adapters over both WiFi TCP sockets and Bluetooth Low Energy, translating raw OBD2 PID responses into clean, readable data in real time.
Diagnostic sessions are stored locally for offline use and sync to the DDPC platform when connectivity returns. The app is an extension of the garage — not a standalone tool.
