Love the App and Web Version

I researched a number of filament management solutions and opted for Spoolstock because of the web-based version. I’ve been using both the app and web-based version for about a month and they’ve been great!

Needs better empty spool management

I’ve been using this app for at least a couple of years now. And I can’t live without it. But here recently with an update things were changed with regard to empty spool weight and management. Normally when I got a new spool and I didn’t know the spool weight I would weigh the spool, and anything over 1kg I put that down as the empty spool weight. And that worked great for me. What I didn’t know is every time I did that the weight was put into the empty spool list. Now I can’t input a spool weight directly. I have to select from the empty spool weight and I have a very long list. I currently see no way of deleting unwanted spool weights so my list is quite cluttered now. And the only way to add an individual spool weight to a spool is to add a new empty spool weight through the empty spool list. Personally what I would like to see is a way to input a spool weight with the option to save it to the list or keep it just for that one spool. And have a way to manage the empty spool list in such a way that we can delete empty spool values or edit them.

Most filaments missing in database

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.

NFC does not work

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?

Hobby Project

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.
