Comments on Fast STL Viewer for Android

★★★★★ Good Will · Mar 14, 2026
Hands down the best STL viewer. Ads are totally manageable.
★★★★★ Adam Albanese · Mar 7, 2026
Works well. Don't use it much but its simple and the ads are quietly at the top if you're looking for a free viewer.
★★★★☆ Mark C · Dec 17, 2025
Great App!!! Please consider adding a 'Lifetime' payment option to remove all restrictions etc. No idea how others like to play, but unfortunately, I will not pay for any App on a subscription basis. Thank you! 👍🏼👍🏼👍🏼
★☆☆☆☆ Deepak kumar · Apr 18, 2026
It shows basic stl file and every time it is opened it plays a video with audio ad and quote literally even if I view one file after another for each file it shows ads. Ridiculous to use for free viewer. EDIT : For response from developers, then there is a bug in the code it's really popping for me every time I open the file. It's a nightmare. Also, we open files from files app sometimes and the app probably considers them as closing and reopening. You will lose every download with your response.

I liked using this app to view stls, but now I'm getting long ads every time I open a file to view it. Very annoying and had to uninstall.
