About this app

TrailerCheck Pro is the official companion app for the TrailerCheck Pro hardware testing box. Designed for both heavy-duty semi-trailers and light-duty RVs, this application allows you to connect to your testing hardware via Bluetooth to wirelessly control and diagnose trailer lighting and electrical systems.

Whether you are a professional mechanic, fleet manager, or trailer owner, TrailerCheck Pro streamlines the inspection process by putting full control in the palm of your hand.

Key Features: • Wireless Light Control: Instantly toggle brake lights, tail/running lights, clearance lights, turn signals, hazard lights, and auxiliary power without repeatedly walking back and forth to the cab. • Live Telemetry Data: Monitor real-time voltage, current draw, and power consumption to quickly identify shorts, bad grounds, or wiring faults. • Multiple Trailer Modes: Easily switch between configurations for Semi/Heavy-Duty and RV/Light-Duty trailers. • Seamless Connectivity: Fast and reliable Bluetooth Low Energy (BLE) connection automatically syncs the app to your testing box. • Over-The-Air (OTA) Updates: Keep your TrailerCheck Pro hardware up to date with seamless firmware updates pushed directly through the app.

Important Note: This application requires the physical TrailerCheck Pro hardware testing box to function. It uses Bluetooth strictly to connect to the hardware device and does not use location data to track your physical whereabouts.
