About the app

BearingTrue Field Lab is a field laboratory for map-and-compass skills. Built for orienteering beginners, geography and outdoor-education students, SAR instructors, and anyone who wants to sharpen bearings, pacing, resection, and route choice without relying on the internet.

All data stays on your device. No camera, GPS, or sign-up required — just the map in your head and your answers in interactive drills. The UI follows a forest topo / brass compass palette: deep canopy greens, paper contour tones, and warm needle accents.

After a short onboarding flow you land on the Field Lab home with four tabs: Home, Courses, Tools, and Mastery. Progress across five skill pillars is shown on a 0–100 scale; successful tool runs automatically raise your mastery scores.

Course packs

Five seeded orienteering labs with topo excerpts, control codes, landmarks, and keyed solutions to verify your answers.

Woodland Loop
Beginner · 3.8 km · decl −8.5° · scale 1:10k

Mixed hardwood stand with spur ridges and a seasonal creek. 5 m contours; thick vegetation on the east bank. Landmarks: fire tower, creek bend, stone wall, trail junction.

ForestCodes: 31 · 45 · 52 · 67 · 78
Ridge Traverse
Intermediate · 5.2 km · decl −12° · scale 1:12.5k

Open ridge with a cliff band on the south face. Sparse pine, rocky outcrops every 200 m. Landmarks: summit cairn, cliff notch, pine island, col.

RidgeCodes: 12 · 28 · 41 · 55 · 70 · 84
Urban Park Micro-O
Beginner · 1.4 km · decl −3° · scale 1:5k

City park micro-orienteering. Paths as handrails; flower beds as catching features. Landmarks: bandstand, duck pond, playground, south gate.

UrbanCodes: A · B · C · D · E · F
Rescue Rally Point
Intermediate · 4.6 km · decl +6° · scale 1:10k

SAR training grid. Rally at a grid intersection; multiple attack points from a forest-road handrail. Landmarks: forest road, abandoned cabin, helipad LZ, ridge notch.

SARCodes: RP1 · RP2 · RP3 · LZ
Night Azimuth Sprint
Advanced · 2.1 km · decl +14.5° · scale 1:10k · locked until Mastery

Urban fringe woods at night. Reflective controls; limited headlamp cone; high magnetic declination. Unlocks when all five mastery pillars reach 40+.

NightCodes: N1 · N2 · N3 · N4

Each course opens a detail page with topo summary, landmarks, control codes, scale, and declination. Filter by difficulty — Beginner, Intermediate, or Advanced — to find the right pack fast.

Field tools

The Tools tab bundles four interactive modules for practice off the trail. Every calculation is checked against keyed course solutions.

On Home, the “Today’s bench” card jumps straight into the tools hub — Bearing · Pace · Resection in one tap.

Skill mastery

Mastery tracks five pillars. Each successful run in tools or deck scenarios raises your score from 0 to 100.

Bearings

Forward/back azimuth, declination, scale math.

Pacing

Double-pace, timed legs, distance conversion.

Resection

Two-bearing fixes, terrain association.

Legend

14 flash cards: contours, hydrography, vegetation, cliffs, man-made symbols.

Route choice

6 scenarios: handrail vs straight, attack point, aiming-off, night catching feature, SAR rally, green slash choice.

Legend decks

Cards grouped by Contours, Hydrography, Vegetation, Cliffs, and Man-made. Tap to reveal hints — index contour, depression, spur, marsh, dense undergrowth, impassable cliff, trail junction, and more.

Route-choice scenarios

Tied to real courses: “Creek handrail vs straight” on Woodland Loop, “Attack point on ridge” on Ridge Traverse, “Night catching feature” on Night Sprint, “SAR rally attack” on Rescue Rally Point, and others. After each pick you get a rationale explaining why the safer route wins.

Field gear templates

Checklists for day hike kit, night-O kit, and instructor kit: baseplate compass, topo excerpt, whistle, headlamp, reflective cards, pace beads, first-aid roll, answer key cards. Tick packed items before you head out.

Widget, settings & offline mode

Daily Glance widget — your home screen shows a fresh micro-drill: a bearing prompt (e.g. “Convert 42° true → magnetic (decl −8.5°)”) or a legend flash with a symbol name. Refreshes locally via WorkManager — no network.

Settings:

BearingTrue Field Lab collects no personal data and needs no camera or internet. Everything runs on-device — great for camps, classrooms without Wi‑Fi, and field sessions.

Frequently asked questions

Does BearingTrue Field Lab need the internet?

No. The app is fully offline: courses, tools, legend decks, and the widget all work without a network or account.

How do I unlock Night Azimuth Sprint?

Raise all five mastery pillars — bearings, pacing, resection, legend, and route — to at least 40 points each. Progress builds from successful runs in Tools and Mastery.

What is Bearing Bench vs Pace Lab?

Bearing Bench drills azimuth, back-bearing, declination, and course scale on an interactive dial. Pace Lab focuses on tempo: double-pace, distance conversion, and timed legs.

Does the app use GPS or the camera?

No. It is a map-and-compass training simulator — no geolocation, no photos, no external services.

How does the Daily Glance widget work?

It surfaces a daily bearing micro-drill or legend flash. Updates happen locally through WorkManager; open the app to check the full answer or run the deck.

Can I change units and theme?

Yes. In Settings, toggle metric units, set default declination with the slider, and pick system, light, or dark theme.

Who is Field Lab for?

Orienteering beginners, students, SAR instructors, hikers, and anyone who wants to practice resection, route choice, and map legend reading before a real event or expedition.
