outstanding application
Love CalTopo!
Great for saving tracks!
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.
Map tile download too slow to use. Luckily there are better and more privacy friendly apps than this.
Have used SARTopo for years. Love both these tools / Apps. Huge improvement to my trip planning.
Refactor and some bug fixes.
