Ratings and reviews

I've been doing hardcore wilderness/ off trail navigation for 30 years and finally a SERUOUS nav system. not just an app, A system. web app allows me to plan and set routes. walk-by-gps app works fine, but I use compass+map and the maps made with CalTopo are second to none. LOVE this system, can't speak highly enough of it for serious /hardcore nav geeks. I hate subscriptions for software, but this is one (the ONLY one) I buy - it's THAT good.

I have been invested in the Gaia platform so if I am to switch to Caltopo, I need a more similar experience. One of my favorite features of Gaia is the folder structure. Looks like your app has similar features but a little different. Please consider a more Gaia approach. Your app turns on all points right away when loading a map and then have to deselect. Not bad app but inconvenient ways of doing things.

I don't like that Google offline maps expire after 1 year. I want maps that I can use for years without an internet connection. I thought this could do that....it can't. You have to subscribe for $20/year. I would pay a 1 time price if it meant my maps would work forever, but even that isn't an option. I'll keep looking I guess. To tech support: I know your maps don't expire like Google maps which is why I downloaded the app. But if subscription renewal isn't possible then the app stops working
