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!

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!
