### 5/5 — Just

*2026-07-31, version 26.27.0*

Pay for it.

### 5/5 — Great mapping

*2026-07-27, version 26.27.0*

Super user friendly and nice interface. Great features and I love all the different sports!

### 1/5 — Data grab

*2026-07-26, version 26.27.0*

Them moment you open the app they are asking to register. No trail period. Straight to the data grab

### 5/5 — Great for urbex

*2026-07-26, version 26.27.0*

good offline maps and gives you elevation levels and stuff ik it’s mostly used for hiking but also another good use for the app

### 1/5 — Not as good as Far out app

*2026-07-23, version 26.27.0*

The reason I downloaded it was I kept seeing the ads they push in youtube. I tried it. Not impressive. Far out is way better. But apparently they push in youtube too much, and much of my subscription money would go to the youtubers than actually making the app better. Would not recommend.

### 5/5 — Great customer support

*2026-07-22, version 26.27.0*

I had questions regarding on-trail use of the app. Haley was very helpful and even gave me extra unsolicited tips which were helpful.

### 1/5 — Do not buy the memberships it is not worth it!

*2026-07-22, version 26.27.0*

The PAID filters are nice. But why are you not able to filter through different types of climbing. Having to sift through every single pinger to see if it’s rope or sport or bouldering is not worth it. And I would highly recommend not wasting your money if that’s what you’re looking for.

### 5/5 — Researcher

*2026-07-22, version 26.27.0*

We are on many hikes throughout the Cascades. It’s so easy to download your offline map with your hike preplanned and ready to use the tracking feature to document your hike and save it to a folder.  I love all the features and options available in ‘on X Backcountry’ app.
Thanks,

ps: if you don’t have this app, you need to get it!

### 1/5 — Bring back line tool

*2026-07-22, version 26.27.0*

Why did this handy tool disappear?

### 5/5 — Great maps

*2026-07-21, version 26.27.0*

Fantastic maps that allow me to plan backpacking trips with realistic expectations of time and distance
