Scam

Open up program, has large selection of file formats you can upload. Choose any of them and it says an update is available. Skip or Update, does not matter which one you choose, it takes you to App Store to download and pay for app not even related.

Cool

Great app that works perfectly with the STP format!

Donโ€™t download

Immediately after uploading the .ply file I wanted to view a scare-tactic file cleaner app promotion told me my drive was too full to process the file which I know for a fact was completely false.

The โ€œcloseโ€ X button didnโ€™t work.

A complete criminal scam give away.

DO NOT DOWNLOAD THIS APP!

If you do ABSOLUTELY DO NOT CLICK THE FILE CLEANER INSTALL!

Response from developer

Hi, I'm sorry you had a bad experience but I do not get to control the ads shown. The ad shown has nothing to do the app and its functionality. Anyway, I will try to make it easier to dismiss the ad.
