Common questions
Which grid formats does Gridmark support?
MGRS, USNG, UTM, and latitude and longitude in several styles. Choose the display format in Settings, and copy any point in the format you need.
Does it work without a cell signal?
Yes. GPS works without a cell signal. Download or import maps for your area before you go, then open Prepare offline for your trip to see what is covered.
Where can I get maps?
Gridmark downloads USGS topographic, aerial and shaded-relief maps for small areas in the United States (Library, Maps & offline). You can also import your own MBTiles, georeferenced PDF and GeoTIFF maps for anywhere.
How do I move a plan to another device?
Turn on Sync with iCloud (Settings, Personal iCloud sync) on each device signed in to the same Apple Account. Or share the trip as a file with AirDrop, Messages or Files.
What happens if I edit the same plan on two devices?
Gridmark keeps both versions and asks you which one to use. It never silently overwrites your work.
How do I use the Apple Watch app?
Open Gridmark on your Watch, enter a grid and navigate to it using the Watch’s own location and heading. Points you capture on the Watch appear on your iPhone for review.
Do I need to buy it again for my Mac or iPad?
No. One purchase covers iPhone, iPad, Mac and Apple Watch, and Family Sharing is included.
How accurate is my position?
It depends on your device and surroundings. Gridmark shows the accuracy your device reports and refuses stale readings. Always check against your map and the ground.
How do I get a refund?
