Quick comparison table

No app here replaces avalanche training or a rescue-ready partner.

1. onX Backcountry

Best for: GPS navigation and trip planning on both iOS and Android.

onX Backcountry is a GPS map and navigation app widely used by backcountry skiers. What sets it apart is that you can plan a route and then navigate it in the same app, with no exporting or switching tools. The catch is pricing. Check the listing for details before you commit.

2. Gaia GPS

Best for: Skiers who also use one map app for hiking and off-roading.

Gaia GPS covers backcountry skiing alongside other outdoor uses, so one app can serve you year-round. The paid tier costs $4.99 per month and unlocks offline maps and advanced layers. That matters when you lose signal, because offline maps sit behind the paywall.

3. CalTopo

Best for: Detailed terrain analysis and desktop-first planning.

CalTopo is a planning and terrain analysis tool on desktop, iOS and Android. It syncs between web and mobile and works offline. It suits skiers who plan on a big screen at home, then navigate from a phone on the skin track.

4. Backcountry SOS

Best for: A backup way to call for help in remote terrain.

Backcountry SOS is a free app for managing emergencies, available on iOS and Google Play. Its main draw is the backup call-for-help function.

Think of it as a safety net, not a navigation or planning tool. It doesn't replace a beacon, probe and shovel.

5. Avalanche Forecasts

Best for: Checking avalanche conditions before committing to a route.

Avalanche Forecasts provides avalanche forecasts for backcountry skiers. It also caches the data you've viewed so you can read it offline.

Only viewed data is cached, so read the forecast before you leave cell service.

6. OnTheSnow

Best for: Snow reports and conditions on a budget.

OnTheSnow is a free ski app on the Apple App Store and Google Play. It puts snow reports and conditions in one place.

Know its limits. It's a general ski app, not built for backcountry route-finding or avalanche safety.

Frequently asked questions

What is the best app for backcountry skiing?

onX Backcountry is our pick for navigation and trip planning. It works best paired with a forecast app like Avalanche Forecasts.

Do I need offline maps?

Yes, plan on it. Cell service is unreliable in remote terrain. Gaia GPS puts offline maps behind its paid tier, while CalTopo offers offline capability.

Can an app replace avalanche gear?

No. Backcountry SOS is a backup only, and you still need a beacon, probe, shovel and a trained partner.

Are there free options?

Yes. Backcountry SOS and OnTheSnow are both free.

Where do I check avalanche risk?

Use Avalanche Forecasts, and view the data before you lose service so it's cached for offline use.

The verdict

onX Backcountry is the strongest overall pick for navigation and trip planning. Gaia GPS is the runner-up for skiers who want one map app across several activities. CalTopo is the runner-up for terrain analysis and web-to-mobile planning.

Add Avalanche Forecasts and Backcountry SOS as safety layers.
