### 1/5 — Scam

*2026-02-03*

As others have said, it’s useless-whether you buy the subscription or not

### 2/5 — Can’t use it

*2025-05-09*

All I want to do is open a G-code file to look at it. Nope! That’s for the premium version. I cannot see any of the capabilities of this app without an annual subscription.

### 1/5 — Pretty useless without a subscription

*2024-09-06*

Disappointing. Not much utility without paying.

### 1/5 — Shuts down after deleting

### 1/5 — Sequence

*2023-11-07*

No colours, no ability to zoom on iPad pro

### 2/5 — It seems good until

*2023-06-01*

It’s decent I open it up everything looks fine until I have to get the plus version in order to export decode or import STL’s which is what I need.  After buying a printer, filament and etc. it is very much out of my price range. I opened up the app in hopes that I would have a free way to get my files sliced and imported to my printer I guess not. Is it possible you guys could add ads instead of making us pay for the plus version.
