Smart NFC filament & spool tracking for Android
17 followers
SpoolTap is a standalone Android app to manage your 3D printing filament—no servers or Docker required. Built with Jetpack Compose, it uses affordable NFC tags to instantly track and update spool weights with a simple phone scan. Perfect for stock printers (Bambu, Prusa, Anycubic) where server setups are too complex. It features a modern Material You design and is a fair, one-time purchase with absolutely no subscriptions or ads.









How does the app handle a filament swap mid-print if the NFC tag is still on the spool you just pulled off, does it auto-pause or is that all manual?

There might be a slight misunderstanding of how the app works!
SpoolTap is a passive tracking utility and does not connect to or control your printer. It won't auto-pause your print because it doesn't know what the printer is doing in real-time.
Instead, it's designed for your manual workflow: you simply tap the spool with your phone before or after a print (or when weighing it) to update and log the remaining weight in your digital inventory. It keeps your stock organized without interfering with the print job itself!
Tapping a cheap NFC sticker on my Bambu spools and seeing the weight update instantly without spinning up anything was a genuinely nice surprise, and the Material You layout feels right at home on my phone.
@blahgeputc93775 Thank you so much for the awesome feedback! I'm thrilled to hear that the instant NFC workflow and the "Material You" layout are hitting the mark for you. That seamless, no-latency experience is exactly what I was aiming for.
Just a quick tip in case you haven't tried it yet: you can actually read the integrated NFC tags on your Bambu Lab spools directly with the app. No extra stickers needed!
Thanks again for your support on Product Hunt!
Tapping a tag and seeing the spool weight update instantly is genuinely satisfying, and the lack of any server setup makes it actually usable for my Bambu setup. Material You looks clean too.
@tanerklnamvsz6 Thanks a ton for the great feedback!
"Genuinely satisfying" is exactly how it should feel.
Thanks for the support!
The Material You theming is a really nice touch, especially for a tool that lives on your phone constantly while you swap spools. Loving that it leans on NFC instead of forcing people into a whole server setup.
@onarsevil55307 Thanks a lot for the feedback!
Love that you went with NFC tags instead of building yet another proprietary scale system. Smart call for the stock-printer crowd who just wants to tap a spool and know what's left.
@okandg58 Thank you! That means a lot.
You absolutely got the vision behind it.
Thanks for the great feedback and for supporting the launch!
finally someone made filament tracking that doesn't ask me to spin up a whole home server just to weigh a spool. love that it's a flat one-time buy too, no subscription nonsense for what should be a simple tool.
@hsan783217 Thank you so much! You hit on two of the exact reasons why I built this.
I strongly believe that a utility tool like this should just work out of the box without the overhead of maintaining a home server. And I'm totally with you on the pricing—no one needs another subscription in their life just to keep track of their filament. A simple tool deserves a simple, honest one-time buy.
Thanks for the awesome feedback and for supporting the launch!
