Grit v2.0, the thruhiking app from OpenLongTrails.org, is now available on iPhone and Android

Grit v2 is now available on iPhone and Android! Version two is a complete rewrite and includes built in maps. As of June 24, 2026, the app is in a public beta test and the current version is 2.0.6. It is stable and hikers are using it on the Pacific Crest Trail right now.

Here's a quick demo video:

What's Grit?

Grit is a thruhiking app that works offline and the PCT is the first trail we've added. It's entirely free to use, has no ads, and we don't sell your data. v2 is a complete rewrite and includes built-in maps. This is still a testing version and probably will be for a while until we have more feedback about how it runs on different makes and models of phones, but the app works, has been stable so far, and thruhikers are using it on the PCT right now.

Grit is free, libre, and open source (MIT license), and we expect to have the public repo up on Github shortly after the regular, post-beta Play and App Store pages are available.

What's OpenLongTrails?

The OpenLongTrails.org (OLT) mission statement is, "Creating, collecting, and freely distributing information about long distance nature trails around the world." In addition to being a guide app, Grit is another step toward OLT's goal of bringing information crowdsourcing and sharing to the thruhiking community, modestly similar to how Wikipedia.org and OpenStreetMap.org work.

Hikers can submit waypoints and photos in the app, and OpenLongTrails generates a curated, LNT-respecting, openly licensed, freely available dataset that's not locked behind any paywall. This is used for adding new trails to the app, and others who want to can use it in their own projects, too, consistent with the Wikipedia-style CC BY 4.0 license.

Apps come and go. Will OLT still be around tomorrow?

Different parts of OLT have been online in one form or another since 2017, and Grit is built from the ground up to be inexpensive to run and as simple as possible to maintain so that it can be around for a long time. Other elements of the OLT project include LongTrailsMap.net, forecast site LongTrailsWeather.net, the PCT Resupply Metro Map, and the (sparsely populated) LongTrailsWiki.net.
