Description

Filament tracking for 3D printing, without the fuss.

Spool Buddy is a simple, fast filament inventory app made for hobbyists who want to know what filament they have, where it is, and how much is left — without accounts, subscriptions, tracking, or complicated setup.

Add your filaments, organize them by brand, material, color, location, modifiers, and more. Track usage across one or multiple spools, keep drying logs, attach photos, archive old filament, and export or print your inventory when you need it.

Spool Buddy syncs with iCloud, so your filament library stays up to date across iPhone, iPad, and Mac without creating an account.

Features include:

Track filament inventory, usage, and remaining amounts

Multi-spool support for filaments

NFC reading and writing

iCloud sync with no logins

Small, fast, and designed to stay out of your way

Spool Buddy is completely free to use. There are no subscriptions, no locked features, and no required purchases. In-app purchases are optional tips only, for people who want to support the app’s development.

Made by an indie solo developer for people who just want a clean, useful way to manage their filament.
