Loads STLs from my file manager and shows boundary dimensions, exactly like I wanted. No crashes. Perfect for my needs!
★★★★★
Opens stl files from stored files, files sent through WhatsApp for example won't open, it says "shouldn't be opened in fast stl viewer" really helpful, you have to fanny around saving them and then locating them and the opening them. 'Fast' should be removed from title it has one job, and apparently doesn't do that very well, I'll stick to using free online viewer EDIT: now works perfectly, previous WhatsApp bug fixed, small advert at the top which isn't too bad, thank you
★★★★★
Really handy app to quick view stl files.
★★☆☆☆
App forces me to turn off my mobile network connection, additionally. It's completely incapable of opening my STL file on my phone. So much for Fast STL.... Apparently im not the only user to report this and yet the developer pleads ignorance. Ought to be renamed fast fail
★★☆☆☆
This app simply can't open stl files from the file Explorer when trying to open a file from the app, on a Google Pixel phone. Since it also doesn't associate the stl extension with itself, you can't use it at all.
★★☆☆☆
An STL viewer that doesn't open STLs. Different approach to be sure.
