Oregon eFOG app is an electronic reference of the Oregon Regional Tactical Interoperable Communications Field Operations Guide (TICFOG). Its purpose is to increase efficiency in establishing interoperable communications during incidents, create a consistent knowledge base of interoperable communications frequencies and networks, and provide a helpful tool for pre-planning and interoperable communications training and exercises.

eFOG provides users search and information access features, offering a content index with links for quick jumps to reference sections, tables, figures, or images. Navigation links allow users to jump directly to regional quick references as well as add customizable bookmarks called Favorites to develop their own personalized access to critical information for their territory. eFOG can be downloaded and then taken to the field as an offline reference, to be used without the need of a cellular or data connection.

eFOG has been optimized for Android versions 6.0 and above, but can operate with reduced functionality on earlier Android versions. Oregon eFOG is also available download via the Apple app store for Apple iOS devices.
