About Trail Companion: Field Guide
Trail Companion is the app you open before a hike, not after it. Plan the miles, weigh the pack, and know when you have to turn around, all completely offline. PACK PLANNER Build your kit from a catalog of trail gear and see the three numbers that actually matter: base weight, food and water, and what is worn rather than carried. Type in your own scale readings, and watch pack weight as a share of your body weight against the twenty percent line. Start from a day hike, overnight, or weekend kit and adjust from there. TRIP PLANNER Distance alone never predicts a day. Enter the miles and the climb, pick your group's pace, and get a realistic moving time, break time, finish time, and the turnaround time you should honour whether or not you reached the top. Your pack weight from the planner feeds straight in, because a loaded backpacker does not move at day hike speed. Add sunset and it tells you how much daylight is left over. THE FIELD GUIDE Ten chapters written for trail travel: the ten essentials, planning a hike, what the pack weighs, how long the day really takes, feet and blisters, trail first aid and the decision to walk out or stay put, choosing a backcountry site, food storage and wildlife, weather that ends a trip, and Leave No Trace on a busy path. IDENTIFY WHAT YOU FIND On device identification for plants, insects, fungi and lichen, animals, clouds, and rocks. Nothing is uploaded and nothing needs a signal. OFFLINE NAVIGATION Download map packs before you go and navigate with a compass and bearings when there is no cell service. Works fully offline. No account, no ads, no subscription. One optional purchase unlocks the full guide. Estimates are planning guidance. Terrain, snow, heat, altitude, and group fitness decide the real day, so carry the margin.
