How to Navigate by Bearing and Distance on iPhone

Steps

1. In MGRS GPS, select a waypoint and start navigation.
2. Follow the big bearing arrow and watch distance, cross-track, and ETA.
3. Set your north reference — true, magnetic, or grid.
4. Rely on offline declination (WMM2025) when there’s no signal.
5. Feel the haptic arrival alert when you reach the point.

Why it works this way

Land navigation is bearing and distance, and it has to work when the map app doesn’t — no signal, no data. MGRS GPS gives you a glanceable arrow, cross-track to show drift, and an ETA, all referenced to the north you’re actually using. The magnetic declination is computed offline from an embedded World Magnetic Model, so magnetic north is correct even off-grid.

Tips & edge cases

• Match the north reference to your map and compass.
• Cross-track tells you how far you’ve drifted off the direct line.
• Not certified for aviation, marine, surveying, or live-fire — always carry a backup means of navigation.

FAQ

What does the navigation display show? A big bearing arrow, distance, cross-track error, and ETA to your target.

Can I choose the north reference? Yes. True, magnetic, or grid north, with offline magnetic declination from an embedded World Magnetic Model (WMM2025).

Does it alert me on arrival? Yes. There’s an arrival alert with haptic feedback.
