Ratings and reviews

incredibly versatile app for exploring. you get access to several different satellite images, weather, topology, geology, fires, parcel data down to the name of the owner, multiple road overlays, and practically everything else you can imagine. you can stack layers, save routes... this is the most well put together, useful app I've come across. onX doesn't come close.

I used to really like Caltopo. My only problem with it was the inability to "move" tracks between maps. You have to download then reupload. But sometime in the past 6 months, the app has become increasingly buggy. It's ridiculously slow, downloading is almost impossible because the app seems to freeze 95% of the time, and all sorts of other issues. I'm probably going to switch over to Gaia or something else after my subscription is up.

Very good, but hard to create a route on the app. I love the clear topo maps, the tracking and ability to download all the map area info with subscription. Creating a route and getting stats on it is easy on a computer on the website with a mouse, but in the app I can't find a way to select a trail segment to add. So all I get in my route are straight line segments as I tap, not trail segments.
