SpoolTap
Smart NFC filament & spool tracking for Android
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.
Hey Product Hunt community!
I’m the maker of SpoolTap. I’ve been a software developer for over 15 years, but recently I decided to dive into native Android development using Jetpack Compose. As an avid 3D printing hobbyist, I quickly ran into a common problem: a massive pile of half-used filament spools and no easy way to track their weights.
While there are great open-source server ecosystems out there, they usually require a Raspberry Pi, Docker, or a Klipper setup. I wanted something completely standalone and plug-and-play for casual users or people with stock printers (like Bambu, Prusa, or Anycubic).
That’s why I built SpoolTap. By slapping cheap NFC stickers onto the spools, you can just scan them with your phone to instantly update or check your inventory.
To keep the project sustainable for future updates while respecting the community, I consciously chose a fair, one-time purchase ($5) instead of a annoying monthly subscription or ad-model.
I’m fully committed to polishing this app and adding more features based on user feedback. I'd love to hear your thoughts, questions, or ideas for future updates!
Happy printing!
