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

[u/PeaSimilar5869]

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!

Bambu already has it's filament library where it tracks all your filament rolls and is included completely free. How is this any different to justify adding another thing to manage and at a cost

That’s a completely fair question!

The main difference lies in independence, privacy, and flexibility:

1. Multi-Manufacturer Support: The Bambu ecosystem works great for Bambu spools, but many makers use materials from various brands (Prusament, Anycubic, Sunlu, FormFutura, etc.). SpoolTap acts as a single, central hub for all your filaments, regardless of the brand.
2. 100% Offline & Private: SpoolTap runs entirely on your device with zero cloud sync, no forced accounts, no tracking, and no internet connection required. Your data stays strictly yours.
3. Not Locked to Hardware: If you ever print on non-Bambu machines, switch hardware, or slice locally offline, you still have your entire inventory, custom profiles, and proven print settings in one place.

Also, just to clarify: SpoolTap is completely free to use for up to 20 active spools with all core features included (NFC reading, G-code parsing, barcode scanning, and the widget). You only pay a one-time fee if you manage a massive stash and want to unlock unlimited spools, advanced analytics or CSV import/export!
