NorthStar Compass is a high-precision, fully offline navigation tool built for North American outdoors — hikers, campers, hunters, RV travelers, and boaters who need reliable direction data without depending on a network connection.

🧭 COMPASS
• Large, easy-to-read compass rose with smooth sensor-fusion readings
• Switch between Magnetic North, True North (GPS), and Grid North
• Real-time azimuth degrees + cardinal direction (N, NE, E…)
• Auto magnetic declination — calculated from your GPS position using built-in geomagnetic data
• Low magnetic interference warning when accuracy drops

📍 COORDINATES & ALTITUDE
• 6 coordinate formats: Decimal Degrees (DD), DMS, DDM, UTM, MGRS, Plus Codes (OLC)
• Real-time GPS latitude, longitude, altitude
• Geomagnetic field strength display (nT)
• Default imperial units (feet, miles) — switch to metric anytime

🔵 SPIRIT LEVEL
• Precision bubble level using accelerometer + gravity sensor
• Pitch & roll angle readout to 0.1°
• Green "LEVEL" indicator when device is flat

📌 WAYPOINTS
• Save your current GPS location with one tap
• Add custom coordinates manually
• Organize by group (Hiking, Hunting, Camping…)
• Distance and bearing to each saved point — sorted nearest-first
• Edit, delete, notes — everything stored offline on your device

🪟 FLOATING COMPASS
• Draggable compass overlay that floats above any app
• See your heading while using maps, messaging, or any other app

🎨 DISPLAY
• Material 3 design — clean, high contrast for outdoor bright-light use
• Auto dark mode for night navigation
• Portrait lock — no accidental rotation in the field

🔒 PRIVACY FIRST
• Zero ads, zero trackers, zero data collection
• No account required
• Only permissions used: sensors + location (while using the app only)
• Works 100% offline — no network required for any core feature

🇺🇸 BUILT FOR NORTH AMERICA
• Tuned for US and Canadian geomagnetic conditions
• Imperial units by default (miles, feet, knots)
• Tested on Pixel, Samsung Galaxy, and Motorola devices

Lightweight (<20 MB), battery-efficient, and compatible with Android 8.0+.

Perfect for: backpacking, hunting, overlanding, boating, orienteering, geocaching, surveying, and any activity where knowing your direction matters
