Poor user experience in recent updates

I’ve used this app for years. While it’s never been the most feature rich, it’s been perfect for navigating crags, getting route beta, sharing info, etc.

Recent updates have really deteriorated this with small bugs making for a frustrating experience. Features that previously worked have broken.

For example:
- Duplicating ticks
- Scroll jumping to the the top when I’m trying to read comments
- “Routes next door” going to the left most route instead of the one I’m currently on.
- App sync’ing data every time I open it. Why would this be necessary?

These have been issues for months and I’ve submitted multiple bug reports through the app. The only one that’s been fixed is the duplicate ticks (maybe because it upped their database costs).

OnX, please do better here. These are simple bugs. They should be caught by the most basic of test suites. This app has been used and appreciated by the climbing community for years and it’s a disservice to give an increasingly broken experience.

Intentional Sabotage

I’ve used this app/website for 7-8 years. In the last couple of years, new app updates have slowed performance, removed community features like forums, and in general worsened user experience. Every time I open it, the app syncs large amounts of data for offline areas now with no option to lessen the update rate or select which areas to update.

The only explanation I have for the more recent changes and how they’ve progressed is that the company that acquired this app/website is intentionally bogging it down and trying to drive away users so that they don’t need to pay for upkeep. 2 stars because it’s still useful if you can get it to work and the website still has good forums no longer available on the app. For reference it takes 5-10min for me to search for a route that I have downloaded when in service now

Genuinely bad app

This app has less functionality than the website, crashes and bugs out all the time, and is just generally awful compared to the website. Super frustrating.

Broken

The most recent update has completely broken the app. It’s permanently on syncing with the red bar at the bottom and I cannot load any tick lists. When I go to any route it continuously jumps back up to the top of the page. I’ve deleted and reinstalled already. Nothing is fixing it

Website has more features

To start, the biggest advantage to having this app (especially on the phone) is having a catalogue of documented routes to search for. When I’m in an area with no service and I’ve downloaded things ahead of time, the info is quite useful. Now, the disadvantages. No ability to comment on routes in the app, and no way to see any of your lifetime stats or even your profile. These features are available on the website but not the app, and I’m wondering why? The app seems like the most logical place to have those features, so disappointed with that and probably will use the website more than the app.

Every update breaks the app

Please stop "fixing" the app. Otherwise mp is a great app. Im just frequently annoyed with it

Most recent version 4.7.6 (Build 1580) not working

Newest version 4.7.6 released 9/2/26 constantly syncs and does not operate properly. Virtually unusable currently

The best

best app if you want to climb outdoors. youll find so many routes you never would have known about. amazing amount of users that drop routes and betas, and give a bunch of info abt routes

Forums Please

Need to bring back forums to the mobile app

Don’t Miss Book Guides

Much better than the days of carrying around heavy books that were ever going out of date.

Used to be great

Ever since OnX bought it it has gone down hill. Removing forums, removing the ability to comment in the app, and frequent crashes. Wish there was an alternative.

Forum removed :(

I miss the forum section

Many bugs and inconveniences

The "Routes next door" feature is maddening to use. It doesn't show the route next door because it shows the leftmost route at the entire crag. A large crag like North Forty can have over 100 routes so you constantly need to scroll. This is a simple feature, just show the current route so one doesn't need to scroll back to your place. This and lots of other glitches makes for a frustrating day

Repeating ticks bug

Please fix the bug that automatically ticks a climb hundreds to times!!

Buggy, more so as of late!

Bugs: double tick created on a tick, “routes” Nextdoor always defaults to the first route in the area

Love the idea of the app and contribute on website

Duplicating Tick & Technical Errors

App now duplicates ticks. Had to delete the app and update on website. Lost all my saved areas.

Do more, OnX. Please.

This could be such a great app. It’s a decent app that comes from a good website. But the functionality needs to be implemented more. So many features on the website need to be brought to the app. Adding images to a route? Details on when crags are shaded or in the sun? The little things. And make it more navigable.

They removed the forum tab from the app

App is still great for beta and route info but forum are no longer accessible from the app, bummer. Nice to find partners, gear, etc. on the forums.

Downhill

Slow and clunky to the point of being unusable. Used to work fine but whatever they’ve added under the hood since Onx bought it has made it useless.

Forums

What happened to the forums portal web link feature? This critical feature was the most used part of the app for many. Please restore
