STL Master

I needed a way to view stl files and this does that and runs well on my phone. It has its quirks but I use it often. The dev could add more color options and turning the metal slider down has helped on certain models that look funny at first load. And it’s completely free, small, and no trackers or spying!

First time I opened a file it wasn’t oriented right and I could not see most of it. Second time, it was centered in the viewport. Seems OK, just basic surfacing options. No menu items (like for Open File). Can’t drag and drop a file into the window to open it, or onto the icon. That is BASIC Mac functionality stuff. The “cloud” icon is for open, that doesn’t make sense. View buttons on the bottom don’t close their menus, you have to click in the window to hide them. OK, easy to try options, but clicking the button again doesn’t close them. No way to zoom in/out.

I like this, but my suggestion is to give the units the measurements are in. I assume it’s millimeters. Also, it may be worthwhile to give the ability to change units from metric to standard.
