### 1/5 — Most filaments missing in database

*2026-04-11, version 2.7.3*

Most every filament I scan are not in the app’s database. Adding a filament by hand is not easy or adds to my quality of life.

### 1/5 — NFC does not work

*2026-03-24, version 2.7.3*

I downloaded this because it said it could scan NFC codes and print labels. The two features I was looking for. There is no help in the app and the FAQ mentions “custom NFC tags” but the main description and images do not. it will not read any Bambu filament tags at all. At least not the 5 I tried. Including setting one on the phone. Is the NFC part hyperbole/ false or is there something o missed in the non-existent documentation?

### 1/5 — Hobby Project

*2026-02-04, version 2.6.6*

This app barely gets any updates, long standing bugs are never resolved. Discord is dead, tickets are never acknowledged. This is a hobby project, so if you’re happy with current app then great. Just don’t expect much more.

### 1/5 — Log in and data GONE

*2026-01-06, version 2.6.6*

After the last update, I can no longer access my spool database. Asking for a password reset does nothing. Did I just lose all my catalogue of spools?!?
Update. 2 weeks later: no contact from company after emailing them. Requesting auto password reset does nothing. 
Just requested a refund thru Apple. 
DONT WASTE YOUR TIME CATALOGING FILAMENT WITH THIS APP. WORTHLESS.

### 1/5 — Log in and data GONE

*2025-12-27, version 2.6.6*

After the last update, I can no longer access my spool database. Asking for a password reset does nothing. Did I just lose all my catalogue of spools?!?

### 1/5 — Locked in

*2025-12-20, version 2.6.6*

The app is ok. NFC doesn’t work. Csv export doesn’t work. Be careful. You can only have 20 spools for free. After that they want money. You can’t export your scans. That’s really bad.

### 4/5 — Slicer push

*2025-12-01, version 2.6.6*

I like the app definitely helps with keeping inventory of colors and brands as well as the war code options seams cool haven’t used it yet myself. . However it would be better if you could link it to your slicer to import your project instead of having to manually input it. Any chance we’ll be seeing integration options like that??

### 3/5 — Instant uninstall

*2025-11-08, version 2.6.5*

As soon as I saw only a paid subscription I uninstalled. I’ll continue using my excel spreadsheet before I pay a monthly fee on something I might use a few times a month. I agree the developer needs to be paid but give me a one time option.

### 2/5 — NFC tag Scan does not work

*2025-11-08, version 2.6.5*

Tried to add filament via scanning BBL NFC nothing happened. Help!

### 4/5 — Suggestion

*2025-10-11, version 2.6.5*

Great and extremely helpful tool. I would give one more start of could easily identify w/spool and refill. Perhaps lees important as I use more. I just like to have a good selection for what if. :-)
