The honest part
Most apps charge for the things you need when it goes wrong.
Offline maps and a way to tell someone where you are shouldn’t sit behind a renewal date. They don’t here. We charge for the data that costs money to license and rebuild — parcels and advanced terrain — and for nothing else.

What you get without paying anything
Record it, wrist included
Battery-aware GPS that knows the difference between a paddle and a ski tour. Live elevation, pace and distance, on the phone or the Apple Watch.
Safety isn’t an upgrade
SOS, live location with friends or emergency contacts, and cell-coverage maps for every carrier — so you know where the signal stops before you get there.
Trail discovery
“Trails within 30 minutes drive”
Ask in plain words and Trailmonger maps the area you can actually reach by road — not a straight-line circle drawn around you — then ranks the trails inside it. Drive, bike or walk time.
