I use and teach teams to use Caltrop extensively for search and rescue. What an incredibly great platform for doing what we need to do.
★★★★★Adrian Huber· Sep 7, 2026
Very versatile and useful tool for mapping, planning, and organizing trips, search and rescue operations, and general landscape awareness by use of the Copernicus satellite views. Excellent tool.
★★★★★Ivan Večanski· Jun 8, 2026
If you love maps this is the app for you. Tailor the map to your likes and add your tracks. Print it if you're out for a hike in the wilderness. Really useful
★★☆☆☆Pat Heron· May 9, 2026
I used to love Caltrop. Recently. The interface was changed, and I don't like it. I want to change the contour interval on my map, but apparently I am not allowed. Was the functionality of the basic subscription reduced? I may have to download my tracks and switch to a different service.
★☆☆☆☆Wahots Wolf· Jul 25, 2026
Completely useless without the ability to download offline maps. For an app. To be used. IN THE MOUNTAINS.
★☆☆☆☆Herb Zinn· May 28, 2026
BUG REPORT: under "map sheets", "add map sheet" says "loading shared map sheets", then hangs the app (on Samsung Galaxy S25 ultra) I can come back 5 minutes later, the whole user interface is greyed out, "shared map sheets" never populates.
★☆☆☆☆Weathered Soul· Mar 29, 2026
Gasps can locate me in my office within a few meters, but Caltrop, with Location turned on and Permission allowed, says it can't locate anything because Location is turned off. Removed Caltrop.
