## Most critical reviews (4 lowest-rated)

### 1/5 — This sucks

*2026-08-02*

You have to pay to do anything. At this point, just make the app paid

**Developer response:** Viewing all twenty-plus model formats is free; only advanced features (such as exploded views and cross-sections) and model format conversion/export come with a fee. You can choose to permanently unlock specific features as needed or subscribe for access to the full suite of functions.

### 2/5 — Size Limits

*2026-07-03*

I paid my $3.99 only to find out the file I wanted to work with was too big. Very disappointing. It’s basically worthless for anything remotely complicated.

**Developer response:** We’re very sorry for the inconvenience and disappointment caused by the file size limitation. We completely understand your frustration, especially after purchasing the app and finding that your file could not be opened.

Could you please let us know the size of the file you were trying to load (how many MB, or GB)? We’d like to better understand the situation and see if we can help.

If the app doesn’t meet your needs, you can also request a refund directly through the App Store. Alternatively, please feel free to contact us at [danjian42@gmail.com](mailto:danjian42@gmail.com), and we will do our best to assist you.

Thank you for your feedback — it helps us continue improving the app.

### 2/5 — Can’t open any STL Files!

*2026-03-18*

This app shows failure to load when trying to read any STL files. It won’t load STL files that other apps will. It does work with other supported file types.

**Developer response:** Please send any files that caused the failure to me: danjian42@gmail.com, seriously. Thank you for you feedback.

### 5/5 — My favorite 3d print slicer app

*2025-12-29*

It works well
