### 5/5 — Great app

*2026-03-07*

It would be awesome if it were possible to add UPCs and be able to add by scanning them. It would be great if this could generate labels with QR Codes also!

### 5/5 — Awesome app, Easy UI and so many preset filaments to choose from

*2026-02-09*

Really like the app, it’s pretty much exactly what I need and is designed really nicely from both a UI and UX perspective. 

The one feature that is missing for me personally is the ability to have multiple storage locations that are easily viewable. There is the option to add a storage location but no way to sort by those. I have printers in three locations and being able to track what I have stored at each location would be really beneficial. Any chance you could add that feature, whether it be adding location as another way to sort or if you add different locations to switch between similar to how HomeKit lets you swap between different homes in the app?

### 5/5 — Great filament tracking app

*2025-11-20*

This app is great! Simple & easy to use. I really appreciate the dev taking time to make this and share it with people. Thank you

**Developer response:** Thanks for your kind words, I’m glad you like the app!

### 5/5 — A data nerds dream come true

*2025-11-11*

I really just wanted a simple, no-frills app to keep track of the hundred + spools of filament I have lying around. The fact that this app is free, and also has a Mac app that syncs the data is the cherry on top.  I’m off to catalog a bunch of filament now!

**Developer response:** Thank you so much for the kind words! Hope you enjoy the app and please feel free to contact me in case something comes up!
