An OBD2 Bluetooth scanner is required to be plugged into your vehicle's diagnostic port under the dash of your vehicle. TruLog works with any commercially available OBD2 Bluetooth scanner such as an ELM327.

Put an OBD2 Bluetooth scanner in all your vehicles, or carry a paired scanner from vehicle to vehicle to document all your drives on one phone - TruLog automatically keeps each vehicle's drives, statistics, diagnostics and data organized by the vehicle's unique vehicle identification number (VIN).

Your privacy is strictly protected with TruLog. All your drive data are only stored on your phone. TruLog will never send any drive log or personal information off your phone unless you do so purposely such as by email using the SendLog feature.

TruLog is the ideal utility app for professional, personal driver and small fleet logs, accurate tax records, irrefutable business expense documentation, diagnostics/clearing codes, and itemizing all your drives in detail to support maintenance to keep all your vehicles in top condition.
