### 1/5 — Worse app

*2026-07-14*

Worse and not worthed app pls dont buy paid version

### 1/5 — Pathetic Money Waste

*2026-07-06*

I downloaded this because I was too lazy to open my computer to view a model a friend sent me. Fortunately I am not lazy enough to spend money to view more than a single file a day when I have the option of nearly a dozen completely free apps on my PC to look at more than a single model.

### 1/5 — Nur schlecht

*2026-04-30*

InApp Käufe ansonsten eine Datei pro Tag?! Abstürze beim Laden von Dateien. Finger weg!!

### 1/5 — Too many adds

*2026-03-19*

I’m deleting cause you can’t even look at anything anymore

### 5/5 — Love this app!!

*2026-02-19*

Simplest way to open STL file

### 1/5 — Unusable and shameless

*2026-02-17*

Completely riddled with ads. Can’t look at a file for more than 15 seconds without getting an ad

### 1/5 — I paid for no ads

*2026-01-07*

WTF!!!!

### 1/5 — Good viewer, but I miss ad-free software like on Windows

*2025-10-27*

Too much ad with sound enabled, screaming at me at night. After that I’ve decided that will be my last apple device.

### 1/5 — Ad scam

*2025-10-25*

Loads ads every time you look at a file. Junk App!

### 1/5 — The most ads I’ve ever seen and it’s not even close.

*2025-09-10*

Pop-up Ads every 30 seconds. Completely unusable.
