Noozy

Know how much filament is left. And what that print actually cost. Noozy is a filament inventory and 3D print cost calculator. It runs completely offline, with no account and no cloud, and your data stays on your phone. ━━━━━━━━━━━━━━━━━━━━ SOUND FAMILIAR? • Half-empty spool, label long gone, and eyeballing it is off by a hundred grams. The filament then runs out ten minutes before the print ends. • Grams times price per kilo is only the beginning. Electricity, printer wear, failed prints and the hour spent sanding are missing. You sell below cost and never notice. • Five black PETGs from three brands look identical. Without a label you can't tell which one was cheap and which wasn't, or how much is left. ━━━━━━━━━━━━━━━━━━━━ AN INVENTORY THAT ADDS UP Every spool has a record: grams left, where it sits, whether it's on a printer, when it was last dried. Subtract by hand, or just weigh the spool — the app works out the rest from gross weight and tare. • List or grid, grouped by brand, material or color • Remaining amount in percent and a color dot matching the real shade • Filters: running low, opened, on a printer, needs reweighing • Bulk actions via long press A CALCULATOR THAT DOESN'T LIE Pick a spool from stock, enter grams and print time. The app adds electricity from your printer's draw for that material, depreciation, post-processing at your hourly rate, failure rate and markup. You see the whole cost breakdown, not just the result. • Several materials in one print • Depreciation per print or per hour, energy use per material • Discount, quantity, price per piece • Customer and due date, with a reminder as the deadline nears • Finishing a print deducts material from the real spools and logs it in history REFILLS DONE PROPERLY You buy spool-less refills because they're cheaper. The app keeps empty spools and shelf refills apart and pairs them — scan one half, then the other, and you're done. After each one is used up you weigh the empty spool and the tare corrects itself. • Mount a refill from either side — spool or refill • Filament can't be taken off a non-reusable spool unless you say so • Calculated savings against buying original packages IDENTIFY A SPOOL IN A SECOND Print QR labels straight from the app on a regular printer, or save them as images. No label printer? Write A1 on the spool with a marker and the camera reads it. Scanning the EAN off the box stocks the spool with every parameter. • QR codes, EAN-13 and EAN-8, OCR of handwritten IDs • Manual IDs from A1 to Z299, with duplicate checks across the database • Home screen widget for a quick scan NUMBERS YOU CAN ACT ON How much filament per month, average price per kilo, the value of your stock, what's left after costs. A monthly consumption chart and your top 5 filaments. A PRE-FILLED LIBRARY Hundreds of materials from dozens of brands, with empty-spool weights and average prices. The calculator works with real numbers on the first evening, not once you've typed in your whole shelf. ━━━━━━━━━━━━━━━━━━━━ YOUR DATA STAYS YOURS No account, no cloud, no ads. Stock, prices and projects live on your phone only. Export a backup to a file and take it anywhere. ━━━━━━━━━━━━━━━━━━━━ A DATABASE BUILT BY ITS USERS You can create and edit the filament database — weights, prices, EAN codes — extend it and share it. Same goes for the printer database. ━━━━━━━━━━━━━━━━━━━━ OPEN BETA The app is in public beta and everything is unlocked while it lasts: free, with no spool limit. The beta runs at least until 1 April 2027. After that the free version keeps working and the full version will be a one-time purchase — no subscription. You won't lose your data: once the paid version starts, everything stays, the free version is just capped at five spools. Bugs and ideas: [email protected]. Noozy is built by one person, shaped by what people actually miss. Czech and English. Android 8.0 and newer.
