Bear encounter
Food storage guidance is activity-scoped, and the wildlife layer shows corridor and recent-activity data for the drainage you are actually in.
Activities · Land · Skill 2 · Moderate risk
Everything you need. Carried, and known.
Two to fourteen days on foot with your whole world on your back. The margins are water, weather and the distance to help — and all three are things the app can model before you leave the trailhead rather than discover on day four.

02 / What the app enables
Pick the activity. The map configures itself.
These layers switch on together, because they are the set this activity actually needs. You can change any of them; the point is that the default is not a blank topo map.
- Topographic
- Contours, slope and aspect, so a shortcut on the map is a shortcut you can walk.
- Trails
- Official and community-mapped, with condition reports and closures.
- Campsites
- Established sites, dispersed camping legality, and distance from water.
- Water sources
- With community-reported status — the difference between a spring and a dry spring.
- Weather
- Forecast, radar and, where it matters, the fire and smoke layers.
- Cell coverage
- Predicted from terrain, so you know where your check-in window closes.
03 / Failure modes
The ways this actually goes wrong.
Every activity in NavTrax carries a documented failure-mode list, and each entry names the feature that addresses it. Not a disclaimer — a design input.
Waterborne illness
Water sources carry treatment guidance and community status. The medical guides work with the radio off.
Gear failure
The kit list is versioned per trip, so a forgotten filter is caught at the trailhead, and the contingency plan names the fallback.
Weather trapping
Coverage prediction plus the forecast means a satellite check-in is scheduled at the waypoint before the front arrives, not improvised after.
Injury evacuation
Wound triage on the device, then a SAR handoff packet with terrain, landing-zone options and your party’s medical capability already in it.
04 / Practice
What the app assumes you already do.
- Bear-safe food storage
- Guidance scoped to the region and the wildlife layer, not generic advice.
- Water purification
- Source status and treatment method carried on the layer.
- Leave no trace
- Dispersed camping legality shown per parcel where the data exists.
- Camp away from water
- Campsite layer records distance to the nearest source.
05 / Curated kit
The gear list, scoped to this activity.
Pulled from the activity's own equipment profile and matched against the in-app store catalog. Nothing here is a generic recommendation.

What happens when you press the button
Know the water before you need it.
Offline regions, safety-aware routing and the water layer are on Pro. SOS and check-ins are free, always.
