Trail Sense is an offline multi-tool Android app for hiking, backpacking, camping, wilderness survival, foraging, and hunting.
Important
Trail Sense is a tool, and like any other tool you bring into the wilderness, it's essential to have backup equipment and the skills to stay safe without it. Never rely on it alone.

See the project board for the current priority order of planned features. There are no associated release dates. Since Trail Sense is a hobby project that I also use daily, priorities may change as my interests and needs evolve.
