Resolution
The app is great. I did have one question though.
I currently use Avenza. The workflow is to create a map in Caltopo, save it as a big PDF (48x48) with my caltopo pro account, then upload it in Avenza. I mostly use the Forest Service 2016 layer with enhanced relief added. I use very little in-app functionality when I'm out -- I basically just want to see where I'm at on the map.
The problem with the Caltopo app though, is that after saving high resolution tiles of the same area/layers of a PDF that I have in Avenza, the resolution isn't as good. In the app I zoom into an area, then bring Avenza up using the same area and zoom, and the Avenza map is clearly the sharper, more usable image. Am I missing something? This isn't a ridiculous zoom either to some 10 meter section, but a view that'd I'd commonly use when out and about. And when I look at the offline layers part of the app it does confirm that the area I tested is saved in high resolution.

That doesn't sound right, the resolution should be the same as the website and at least as good as the PDF (since the PDF images are stored as JPEGs and there's a small amount lost due to the lossy compression).
Are you sure you downloaded high resolution tiles for both the FSTopo and Elevation layers? If you look at the map with an internet connection available, do you encounter the same low-resolution issues?
