What's New in Mossback
1.3.0
October 16, 2026
Mossback now covers 67 areas, including nearly every US national park, from Yosemite and Zion to Denali, Acadia and the Everglades. There is a new route planner. Tap or drag on the map and the route follows the trails. Drag any stop, undo and redo, close a loop or make an out and back in one tap, and see the distance, climb, time and an elevation chart. Plan as many days as you like and Mossback finds huts, shelters and campgrounds for the nights. Find more to do than hike. Hot springs you can legally soak in, waterfalls, swimming holes, caves, fire towers, birding hotspots, winter routes, tonight's stargazing and when fall color peaks. Hunting season heads ups tell you when to wear orange. Every hike page is laid out the same way now, with a Before you go section and sunrise, sunset and golden hour at the trailhead. Each area has one Rules & info page. Mossback can tell you which way to turn at each trail junction, so your phone can stay in your pocket. Before you go, set a check-in time and text your plan to someone, and Mossback reminds you to check in. The SOS card finds the nearest emergency room anywhere in the United States with no signal, shows trauma center levels, and gives your coordinates to read to 911. Every waypoint shows its coordinates too, with one tap to copy, and you can add a waypoint by typing coordinates in decimal, degrees minutes seconds, UTM or USNG. Fishing has its own tabs, so it works like an app of its own. You can still fish while you hike. Trail crews can turn on crew tools in Settings to log work by trail number and mile, right from a Log work button on the map. Mossback now has a dark mode. Choose Light, Dark or Match my phone in Settings, and it opens faster. Mossback is free, with no account and no ads.
