Compass: Lodestone Wayfinder

Lost in a spot with no signal and no idea which way is north? Compass: Lodestone Wayfinder is a fully offline navigation compass that reads your device's magnetic and orientation sensors to point the way without GPS, an account, or a data connection. Built for hikers, trail runners, backpackers, geocachers, and anyone who wants a reliable heading in the field, it turns raw sensor data into a clear, calibrated bearing you can trust. Everything runs on your phone, all the time.

What sets Wayfinder apart is its precise, honest approach to heading data. It computes your heading in real time, applies magnetic declination so you can switch between magnetic and true geographic north, reports live sensor accuracy and magnetic field strength, and even gives you a subtle haptic tick as you cross cardinal directions. A guided personalization walkthrough tailors the interface profile to how you actually use it.

KEY FEATURES
• Live compass heading - Reads device sensors to compute a smooth, responsive heading with cardinal direction and degree readout right at the display edge.
• True vs magnetic north - Apply a declination value to reference either magnetic north or geographic true north, so your bearings match your map.
• Figure-8 calibration - A dedicated calibration screen walks you through sweeping the device in a figure-8 to restore sensor integrity, with a clear integrity state indicator.
• Bearing deviation guidance - Set a target bearing and see when you are on target, helping you hold a straight line toward a waypoint.
• Snapshot logging - Save timestamped compass snapshots with notes like a trailhead check-in or a north ridge turn, then review them in the log.
• CSV export - Export your logged snapshots to a CSV file via the system file picker to keep or share your field records.
• Editable notes - Attach and update a note on any logged reading so each snapshot has context you can recall later.
• Sensor reporting - View live magnetic field power, tilt pitch, tilt roll, and sensor accuracy so you know how much to trust the current reading.
• Low-pass smoothing & haptics - Optional sensor smoothing steadies a jittery needle, and haptic ticks mark crossovers as you rotate.
• Flexible degree format - Choose how degrees are displayed at the UI edge to match your preference.
• Theme profiles - Pick your visual display environment with a theme profile mode that fits day or night use.
• Guided onboarding & quiz - A personalization walkthrough sets your intended use case, north reference, format style, and theme, and can be re-run anytime.

HOW IT WORKS

Run the quick onboarding walkthrough to set your primary use case, north reference, degree format, and theme.

Calibrate by sweeping your device in a figure-8 until the integrity state reads clean.

Open the compass to see your live heading, cardinal direction, tilt, and magnetic field power.

Log a snapshot with a note at key moments, then export the whole log to CSV when you get back.

PRIVACY
Wayfinder makes no network calls, requires no account, and shows no ads. Your headings, notes, and logs stay on your device, and CSV export happens only through the system file picker when you choose it. GPS-free navigation means it works even where there is no signal at all.

Whether you are checking in at a trailhead, holding a bearing across open ground, or just want to know which way is north, Compass: Lodestone Wayfinder keeps you oriented offline. Calibrate, set your north reference, and start wayfinding today.
