Comments on CalTopo for Android

★★★★★ 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
★★★★★ Denny Salisbury · Jul 22, 2026
This is an incredibly valuable tool for Search and Rescue as well as first responders in general. Caltrop/Sarto has been a game changer!
★☆☆☆☆ 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.
★★☆☆☆ M C · Mar 16, 2026
It's messy and lacks many town names for areas as well as labels for fairly popular hiking areas. Even if these places DID have labels they'd be overshadowed by the ugly way too thick lines haphazardly scribbled all over the map
★★☆☆☆ 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.
★☆☆☆☆ 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.
