Auto Controll

CarControl turns your phone into a full OBD-II diagnostic scanner. Connect any ELM327-compatible adapter over Bluetooth or Wi-Fi and get real-time insight into what's happening under the hood — no dealership visit required.

KEY FEATURES

🔧 Live Diagnostics
Read real-time data straight from your vehicle's ECU: engine RPM, speed, coolant temperature, fuel level, intake air temp, and more — all in one clean dashboard.

⚠️ Trouble Codes (DTC)
Instantly read and clear check-engine trouble codes, with plain-language explanations so you know what's actually wrong before you head to the shop.

📊 Trip History
Automatically log your trips — distance, duration, and key metrics — stored locally on your device so you can track usage over time.

⛽ Fuel Quality Insights
Get diagnostics on fuel-related readings, with honest, transparent messaging about what OBD-II data can and can't tell you.

📶 Flexible Connectivity
Works with both Bluetooth and Wi-Fi ELM327 adapters, with reliable connection handling built for real-world, noisy vehicle environments.

🔒 Privacy-First
All vehicle and trip data stays on your device. Nothing is uploaded to external servers.

WHO IT'S FOR
Whether you're a daily driver who wants to catch problems early, a car enthusiast who likes knowing exactly what your engine is doing, or someone who just wants to understand that check-engine light before paying for a diagnostic — CarControl gives you direct access to your vehicle's data.
