Spoolman GO

Spoolman GO is the Android companion app for your self-hosted Spoolman or FilaMan-compatible server. Manage your 3D printing filament spools, track inventory, and write NFC tags in the OpenSpool format — directly on your Android device.

FEATURES

• Dashboard with inventory overview: total weight, material distribution, low-stock warnings, and vendor statistics at a glance
• Spool list with search, sorting, and filters by material, vendor, location, and stock status, including a remaining-weight status indicator
• Detail view with all filament data, settings, and remaining weight
• Book filament usage and record measured remaining spool weight
• Overview for spools, filaments, vendors, and locations — edit all fields
• Multi-color display: pie chart (coaxial) or linear gradient (longitudinal) in lists and details
• Scan QR codes and open the matching spool directly, including Spoolman URLs and WEB+SPOOLMAN codes
• Read and write NFC tags (OpenSpool 1.0 format, NDEF MIME application/json, suitable for Snapmaker U1)
• Automatically store NFC tag UID on the matching spool (lot_nr)
• Auto-detect API: native Spoolman or FilaMan Spoolman compatibility
• Light / Dark / System color scheme
• Demo Mode: explore the app without your own server using realistic sample data
• No account, no cloud service — all your data stays with you
• Settings: server connection, appearance and language, low-stock threshold
• German and English localization based on device language or manual selection

LIVE MODE & SUBSCRIPTION

Demo Mode works without a server. Live Mode, which connects to your own Spoolman or FilaMan server, requires a monthly subscription. The subscription is managed by Google Play and can be cancelled anytime in Google Play subscription settings.

REQUIREMENTS

• For Live Mode: your own Spoolman server or FilaMan with a Spoolman-compatible API
• For QR scanning: camera permission
• For NFC: Android device with NFC and a writable NDEF tag, such as NTAG215/216

PRIVACY

Spoolman GO does not collect usage data for the developer and does not include tracking. Settings such as server URL, appearance, language, and subscription state are stored locally on your device. In Live Mode, the app communicates only with the server you configure and with Google Play for subscription management.

Recent changes:
• QR and NFC scanning is now available directly from the dashboard.
• Manage two named Spoolman instances and switch between them quickly.
• Add an alternative server address, for example for Tailscale.
• Fixed an NFC assignment issue: the required server custom field is checked and created automatically when missing, including on existing installations.
• Improved instance switching with isolated inventory data.
