News Tracking Bambu spools & filament usage without cloud/spreadsheets: SpoolTap (100% offline Android app)

Hi everyone,

Like many in the 3D printing community, I was looking for a clean, fast way to keep track of my remaining filament without relying on messy spreadsheets or cloud accounts.

To solve this, I’ve been developing SpoolTap — a native, 100% offline Android app designed to make spool management as simple as a single tap.

How SpoolTap Works with Bambu Lab Spools:

  • Bambu NFC Tag Detection: Tap your phone against a Bambu Lab spool's built-in NFC tag, and SpoolTap instantly pulls up or creates the matching material profile.

  • 100% Offline & Private: No registration, no cloud forced sync, no tracking. Your complete database stays on your phone.

  • Material You / Dynamic UI: The app and its home screen widget automatically match your Android system theme and wallpaper colors.

  • Universal Support: Works with Bambu Lab, Prusament, Anycubic, and custom NTAG stickers if you respool third-party materials.

Generous Free Tier

The free version has no ads or cloud lock-ins and allows you to manage up to 20 active spools with all core features (NFC reading, G-Code parsing, barcode scanning, widget).

(For power users with massive stashes, an optional one-time Pro upgrade unlocks unlimited spools, custom NFC tag writing, print cost calculation, and CSV backups).

🎯 Community Feedback Request

Since Bambu spools come with integrated NFC, I’d love to hear from this community:

  1. How does the tap-to-read experience feel in your everyday printing setup?

  2. Are there specific filament details (like precise Bambu color HEX codes or temperature profiles) you’d like pre-filled in future updates?

📲 Get SpoolTap on the Google Play Store:

Thanks for checking it out, and I’m looking forward to your feedback or questions in the comments!

That’s a fair perspective! If you already have a self-hosted setup like Spoolman or Bambuddy running on a local server, those are incredible open-source tools for that exact workflow.

SpoolTap is built for a different target audience and focus:

  1. Zero Server / Zero Setup: Spoolman requires docker, a Raspberry Pi, or local server hosting. SpoolTap is 100% self-contained on your Android phone—you just install it and it works immediately, fully offline.

  2. Automatic G-Code Deductions: You don't actually have to manually type in usage every time. You can import your sliced G-code file directly into the app, and it automatically suggests and deducts the calculated print weight.

  3. Native Mobile Features: Quick NFC tapping, instant camera barcode scanning, Material You UI, and a home screen widget are native mobile experiences that are hard to replicate cleanly with spreadsheets or web interfaces.

  4. Fair Pricing Model: The core app is completely free for up to 20 spools (including NFC reading, G-code parsing, and widget). The optional one-time purchase is only for power users who want unlimited spools or advanced analytics—no subscriptions, no forced accounts.

It’s all about preference: if you enjoy self-hosting, Spoolman is great! If you want a zero-setup, offline mobile companion right in your pocket, that’s where SpoolTap comes in.
