Fast STL Viewer

ABSOLUTELY SPECTACULAR. As an engineer and a regular 3D printer user, this app is by far, beyond the best. I used fusion 360 before which forced you to get an account and upload a file before viewing it and it takes about 1-3 mins to load. this one is intstant! it works out of the box, nothing to fiddle with, just choose the file and it works. boom. Vest stl viewer EVER

The best STL viewer available. I tried many others and even paid for one and they all did not do a great job at all. This viewer allows you to rotate your file on its axis. Not like other viewers that rotate on the backgrounds axis. Absolutely perfect.

Not kidding when it says fast. 150 MB (3.2 million triangles) STL loaded in 2.6 seconds.

It is by far the best app for looking at any STL file for 3d printing or anything else. The quality and UI is very simple and clean.

Brilliant on the go viewer . Even faster on my new Galaxy Tab S2.

Nice, lightweight & super fast to load, just what you need for on-the-go viewing of STL files.

Awesome app we can open all STL files in it. I loved it

It wonderful app to view STL file via phone, fast and Good

Missing color editing

Most valuable software..... :-)

Very quick and useful app.

Is fast and works for me

Easy to use for quick reference

Very handy!

Very fast!

works great

Simple and useful

Works great

It loads outrageously fast. Blink and you'll miss it. On top of that, manipulating the object is buttery smooth. Don't use this app if you like using load times to ponder life's mysteries: you'll get none of that here.

Blazingly fast on my LG G5. The only thing missing is that you cannot Save a file. I.e if you separate the meshes. It would be Awesome to be able to them save as separate files.

Boy, it is fast and looks and runs beautifully!

Perfect ? How to open multiple files though

Does what it promises

Tiny. Very nice

faster than espected

handy, i like it

Tried four other apps, they all rounded my corners in weird ways. This one rendered correctly and was also the easiest to manipulate the view.

Needed to view an STL file that I exported from Onshape. Worked without a single problem on the first try. Very smooth operation and simple UI. I wish it was always this easy.

This viewer has worked well for all of the STL files I've tried. It's also very fast and easy to use.

Has everything you need!

Helped me

Great!

Renders stl files almost instantly! A really useful app for users of stl files like me.

Thank you ### designer......I can esly show my 3d figure to anyone using my handaset

I found this app very useful and highly optimized for displaying large STL files. Thanks.

It moves very smoothly and renders perfectly! Nice options.

Decent, but a bit glitchy. It would not load stl files after the install, and I had to reload the app. There is also a tendency for the app to freeze up when rotating the model or changing the view.

It works fast and we'll, but ASCII support is missing.

Needs to remember last folder reliably (sometimes won't remember) & add a favourite folders list. Ability to load models in same scenes without overlapping already loaded model's. Export to other formats

I like the way this STL viewer displays 3D models, and it is really fast ! The one drawback for me is that it does not access the whole file system, in particular the external SD storage where my models are usually stored. I have to move a model to internal storage in order to display it. This app is a keeper, but I will keep looking for more complete file system support in a future update? Maybe a paid Pro version? =====================================UPDATE ---The author of this app responded to my comment concerning no access to the external SD or USB stick. As of the current app revision he has added full access to the Android file system including external SD access and USB stick access. AND the app is still blazing fast. :-) For me, this app is a keeper for my rooted Samsung SM-T535!!!
