Trailmonger vs Avenza Maps
Avenza Maps is a geospatial PDF reader: it puts your GPS position on individual georeferenced map sheets — Forest Service motor-vehicle-use maps, state park handouts, commercial map sets — downloaded one at a time from its Map Store. Trailmonger is one continuous offline vector map of the United States: free to download with no per-map purchases, with property boundaries, hunt units, stream flow, bathymetry, and tides in Pro. Here is where each one is genuinely better.

How much does each app cost?
Trailmonger Pro is $19.99 per year (or $3.99 per month), and the map itself is free. Avenza’s free tier covers Map Store downloads — many free, many paid per map — but as of 2026 importing your own maps requires Plus at $34.99 per year per device (up to 20 imports); the Pro tier for professional use starts at $169.99 per year.
What does Avenza Maps do better?
Authoritative sheets, anywhere on earth. When the map that matters is a specific official document — a motor-vehicle-use map that settles whether a road is legal to drive, an avalanche-terrain atlas, a race organizer’s course map — Avenza shows you that exact document with your position on it. Its Map Store spans the world, and Plus lets you import any georeferenced PDF you have. Trailmonger cannot display third-party map sheets at all.
What does Trailmonger do better?
Being one map instead of many. There are no sheet boundaries to manage, nothing to buy per quadrangle, and no imports to gate: the whole country downloads free, stays current, and carries live data a printed sheet never can — real-time stream flow, weather, property ownership, and hunt units. Routing, recording, and search work across the entire map rather than inside one PDF at a time.
Is Trailmonger a good Avenza Maps alternative?
Yes, for everyday navigation, scouting, and recording across the United States — especially since Avenza moved personal map imports behind a subscription. Avenza remains the better pick when you need an exact official map sheet or coverage outside the U.S. The FAQ covers what is in the free tier and how offline maps work.
