Gaia lost me with a severe price hike, lack of new features/polish, and the removal of my most-used map layer. In protest, I gave OnX a try. It's fine, I guess. Neither of them have ever worked like I wanted them to.
Avenza has the map layer I want, but has no web-based interface to build routes and add markers. I'm not doing all of that on a phone/tablet. I have too much data to move over. I need a keyboard, mouse, and a large screen to work from.
I'm looking forward to what Mapkind is able to offer.
Mapkind GPS Developer Venture4wd/Chris has lived and breathed maps for years. I know he understands the sort of functionality we need most from a mapping app.
