### 1/5 — Did not work

*2022-06-04*

When I opened the app I got a white screen with blue and red dots.  If this was supposed be a map of some sort there is no map underlay for any reference. If I zoom in far enough and tap on a spot it showed nice pictures of routes but no information.

### 5/5 — Great Regional Tool

*2021-06-01*

Great visuals to accompany a guidebook when planning a climbing trip or getting oriented at a new crag. As a PNW climber, covers of most of the big destination spots (smith / vantage) but hopefully as the app grows it’ll become more comprehensive for the local or less popular crags.

### 5/5 — wouldn’t climb without it

*2019-06-16*

Excellent interface that’s responsive and uncluttered while still giving lots of information — easy and intuitive to use — impressive range of locations!
