I'm sure I don't use this app to its full potential, but I do use it when I'm out hiking and it's such a game changer. It's basically what I've always wanted: to be able to point my phone at a mountain and be able to see the name of it and the distance and the roads and trails that are on it. How amazing is that? I love that I can also track my progress so I won't get lost, mark points if I find an ideal picnic spot I want to return to, and discover new trails. It's absolutely wonderful.

Been using this since the initial beta stages years ago, when it was practically unusable. Since the constant rapid improvements, this has been my only mapping app, and website, I use. It's far superior to others, of which I used them all at one point or another. Happy to pay the annual subscription knowing it helps improve maps for recreation & SAR.

This app has recently rappelled off the end of a rope. I don't know what happened. I have been such a huge advocate for Caltopo. I have convinced at least a dozen people to abandon Gaia and switch. I add features to OpenStreet so that Caltopo can pull them into their layers. With the latest updates, this app is now insanely buggy, particularly when downloading tiles. When I go to download, I get a black screen. Has the app crashed? Has it froze? Hard to tell. After over a minute it finally lets me select map tiles to download. I selected 32MB of files and, 16 hours later, on a gigabit connection...it still says "Download 2 files (32MB)" in notifications. The very functionality I pay a yearly fee for: downloading tiles for use without cell signal, is broken.
