onX (Hunt / Backcountry / Offroad) alternative
A free, open-source onX alternative
onX (Hunt, Backcountry, and Offroad) is a polished, subscription-only app whose real moat is proprietary data: private/public landowner boundaries, parcel ownership, and hunting-unit layers you cannot easily get anywhere else. If that data is why you use onX, no free app fully replaces it — and we will say so plainly.

onX is subscription-only: Hunt Premium is $34.99/yr (one state), Elite $99.99/yr (all states); Backcountry and Offroad are similarly priced, with only a free trial. mapper.one is free.

Why people look for an alternative
But many people pay $34.99–$99.99 a year mostly for offline topo maps, GPS tracks, and waypoints. mapper.one does that part for free: offline OpenStreetMap tiles, your own imported datasets, and field waypoints, all open-source and account-optional.
What onX (Hunt / Backcountry / Offroad) does well
- Proprietary landowner and parcel-ownership data with public/private boundaries — its standout feature.
- Hunting-unit and game-management layers, plus high-resolution satellite imagery.
- Very polished, well-supported apps with offline downloads and routing.
- Specialized variants tuned for hunting, backcountry, and off-road use.
Where mapper.one is different
- Free and open-source — no subscription and no trial clock.
- Bring your own data: import KML, KMZ, GeoJSON, and GPX (including agency boundary files) on the phone.
- Offline OSM basemap caching for true no-signal use.
- Account-optional; your waypoints and tracks live on your device.
Which should you use?
Where onX (Hunt / Backcountry / Offroad) still wins
Stay with onX if you depend on its landowner/parcel data or hunting-unit layers — that proprietary dataset is the reason to pay, and mapper.one does not replicate it. You can sometimes import public boundary data yourself as GeoJSON, but it will not match onX's curated ownership layers.
When to choose mapper.one
Switch (or add mapper.one) if you mainly need offline topo, your own GPX/KML data, and waypoints, and would rather not pay a yearly subscription for it.
Frequently asked questions
Does mapper.one show property lines like onX?
No. Private/public landowner and parcel boundaries are onX's proprietary data and are not built in. If you have public boundary data as GeoJSON or KML you can import it yourself, but it will not match onX's curated ownership layers.
Is there a free tier, or just a trial?
mapper.one is free forever — not a trial. Every feature is available without paying, and there is no subscription.
Can I use it for hunting?
Yes, for offline topo, GPS tracks, and waypoints. Just know it does not include onX's landowner or game-unit datasets — bring your own boundary files if you need them.
