By far the best most detailed topo map out there! I love using the shaded relief map. It shows every fine detail from stone walls to any slight depression. It's spot on! Also all the different features to mark your trails! Thanks!

been using this app for almost two years now.. very useful. i can do lots of things like add marker, record tracks, measure bearings and distance from one marker to another. i can also choose my dwsiref base layers and map overlays. Most importantly, i can save and print specific map with my desired scaling, gridlines and a lot more.. it is, indeed very useful and easy to use. i have one wish, though..-- updated map..

I use Caltopo frequently for tracking hikes and planning on a PC. I mostly really like it because I'm comfortable with maps but it is missing trailhead names, so for recreation using other sources for reference, I'll confirm the coordinates if unfamiliar with the area. Please add support for 24h time format, like when adding a marker it uses am/pm format in the default name even though my phone (and PC too) is set to display 24h clock.
