Arkansas Hiker is a detailed, map-based smartphone guide to Arkansas' best trails. The app currently includes the Ouachita National Recreation Trail, the Eagle Rock Loop, the Buffalo River Trail and the Pinnacle Mountain State Park trail system. Other trails and trail systems will be added over time.
After the initial setup the app is fully functional without an internet connection: NO MOBILE OR INTERNET CONNECTION REQUIRED because the app uses your device's GPS and offline topo maps.
The free demo covers the Pinnacle Mountain State Park trail system, along with 20 miles of the eastern end of the Ouachita Trail.
An elevation profile shows path distance vs elevation and plots your current location. Each waypoint is plotted on the profile. Each waypoints is clickable, opening to the waypoint's detail page.

The types of waypoints include:
-->Water sources (including the reliability of each water source)
-->Tenting sites/camping sites
-->Trailheads and parking areas along the trail
-->State and Federal campgrounds
-->Roads crossings, railroad tracks, power lines
-->Natural landmarks (e.g. views, ponds)
