Founded in Missoula in 2009, onX developed an app that allows users to download topographical maps with other layers before they go out into the backcountry. Then, even when they are out of cell range, they can see land ownership and other layers in relation to where they are standing.

The company has also developed several other products, but its navigation apps include onX Hunt, onX Offroad and onX Backcountry.
