Every spool remembered.
Every make celebrated.
Spoolery is the friendly tracker for 3D printing hobbyists. Snap a label, log a few grams per print, and when a spool runs out the waste is split fairly across everything you made — no spreadsheets, no fiddly parameters.

Features
Three little chores, handled
You do the printing. The weighing, the bookkeeping, the "how much was this spool again?" — that's Spoolery's job.
Snap a label, spool's in
Point at the label and the brand, line, material and finish are recognized. A built-in catalog of 50+ brands and 3,600+ official colors matches the exact shade — no guessing.
Every make becomes a sticker
Photograph a finished print and it's cut out into a sticker, complete with a charming little name. Watch your collection grow into a wall.
True cost, settled per spool
Log a few grams per print. When the spool runs out, supports and waste are split across every piece automatically — "this little cat cost $0.45", exactly.
A rack, a ledger, a collage
Spools stand on a virtual rack, the ledger sorts by cost, and the collage fits your whole collection on one screen. Your stuff, your view.
How it works
Three steps, that's it
New spool? Scan it
Snap the label or an order screenshot — price and weight included.
Print done? Snap it
It becomes a sticker; just jot down the grams.
Spool empty? Settle up
Waste is spread across every make and estimates become real costs.

FAQ
Questions, answered
What does Spoolery do?
Snap a spool label, photograph each finished print, and Spoolery remembers every spool and every make. When a spool runs out, waste is split fairly across everything you printed with it — so you know the true cost of each piece. No spreadsheets, no fiddly parameters.
Do I need an account?
No. Open the app and start. All of your data lives only on your phone.
Are my photos uploaded?
Not by default. Label scanning and sticker cutouts run entirely on-device. You can optionally turn on Cloud Recognition for better accuracy — label scans then send only the recognized text, and naming sends one downscaled photo. You can switch it off anytime.
Which printers and filament brands work?
All of them. Spoolery isn't tied to any printer — Bambu, Creality, Prusa, whatever you run. A built-in catalog of 50+ brands and 3,600+ official colors matches your label to the exact official shade.
What's in the free version?
Track 3 spools and 10 makes with every feature included — scanning, stickers, the rack, the ledger, the collage. Enough to go through a full buy → print → settle-up cycle before deciding to unlock.
Why one-time purchase instead of a subscription?
Your data stays on your device, so we don't run monthly servers for it — charging monthly wouldn't be honest. Pay once, keep it forever, future features included.
Recognition and cutouts are powered by Apple Vision / VisionKit, local storage by SwiftData, and the filament color catalog by the open-source SpoolmanDB project (MIT).
