Gridnord
Gridnord is a GPS coordinate converter for iPhone. It reads your position on the device and shows it as decimal degrees, DMS, DDM and an MGRS grid reference, or recognises a coordinate you paste and converts it to MGRS, UTM, Maidenhead, Geohash and Plus Code. Save waypoints, see them on Apple Maps, get distance and true or grid bearing, hear the grid reference read out in the NATO radio alphabet and export points as GPX or CSV. No account, no ads.
Gridnord is an iPhone app and GPS coordinate converter: it shows your location or any pasted coordinate as MGRS, UTM, lat/long, Maidenhead, Geohash and Plus Code.
Features
- Reads your GPS position on the iPhone and shows it as decimal degrees, DMS, DDM and MGRS, with the horizontal accuracy
- Paste a coordinate in any supported format and it is recognised and converted to all the others: MGRS, UTM, Maidenhead, Geohash and Plus Code
- MGRS at 1 km precision in the free version; 10 m and 1 m grid references with Pro
- Spoken NATO phonetic radio readout of the grid reference, using the iPhone's own voice
- Saved waypoints on an Apple Maps view, with distance and true or grid bearing from your position to any saved or converted point
- GPX and CSV export of saved points; the coordinate math works offline and needs no account
Questions
Which iPhone app converts GPS coordinates to MGRS?
Gridnord is a GPS coordinate converter for iPhone. It shows your current position or a pasted coordinate as an MGRS grid reference, down to 1 m with Pro, alongside UTM, lat/long and other formats.
How can I convert a UTM or MGRS grid reference to latitude and longitude on iPhone?
Paste it into Gridnord's Convert screen. It recognises MGRS, UTM, decimal degrees, DMS, DDM, Maidenhead, Geohash and Plus Code and shows the point as latitude and longitude; UTM, Maidenhead, Geohash and Plus Code output come with Pro.
Does Gridnord work without a mobile signal?
The coordinate conversions are calculated on the iPhone, so they work offline. The map view needs a network connection to load Apple Maps tiles.
Does Gridnord work near the poles?
MGRS and UTM are shown between 80°S and 84°N. The polar UPS zones are not supported; latitude and longitude, Maidenhead, Geohash and Plus Code still work there.
Is Gridnord free?
The free version converts between decimal degrees, DMS and DDM, shows MGRS at 1 km precision and saves up to 3 points. Pro, a subscription or one-time lifetime purchase, unlocks the rest; the yearly plan starts with a 3-day free trial.
How it works
All coordinate math runs on your iPhone and works offline; only the map view needs a network connection to load Apple Maps. Your location is read only while the app is open and never leaves the device. MGRS and UTM cover 80°S to 84°N; the polar UPS zones are not supported.
