1ELD is a free Android application developed by Cartrack Development Team, designed to track hours of service for commercial drivers. The app offers an Automatic Onboard Recording Device (AOBRD) mode, which allows drivers to track their hours of service and make edits, while still providing inspectors with the required information. It is a simple to set up app that can be downloaded and used immediately. Once you are ready, the ELD hardware can be installed for 100% ELD mandate compliance in 1ELD or 1AOBRD mode.

The diagnostic port hardware connects to the app via Bluetooth for 100% FMCSA mandate compliance. With just one button, drivers can change their Record of Duty Status and access ELogs, HOS Logs, DVIR Reports, and Inspection Reports. The app is user-friendly and engine activity and status is automatically detected and updated. The app also eliminates the need for paperwork and allows for easy electronic sending of logs via email or fax. Additionally, the app provides automatic alerts and notifications for all Shift and Cycle violations in real-time.
