Everything Noozy does

Feature overview for version 0.901beta. The app runs fully offline; data lives on the phone only.

Inventory

One list holds three kinds of item: a spool with filament on it, an empty spool waiting for a refill, and a loose refill sitting on the shelf.

Overview and organisation

  • List view (detailed) or grid view (compact)
  • Grouped by brand, material or colour
  • Identical items merge into one row with a count and total weight
  • Remaining amount shown as a percentage
  • Colour dot matching the real shade, including multi-colour filaments

Filtering and search

  • Full-text search across brand, material and colour
  • Filter by item kind, brand, material and colour
  • Filter by the letter and number of a manual ID
  • State filters: loaded on a printer, running low, needs reweighing, opened
  • Live count of matching items inside the filter dialog

Working with a spool

  • Subtract material manually or by weighing (gross weight minus tare)
  • Reweigh to correct an estimated amount
  • Unload a refill back into stock (reusable spools only)
  • Mark as used up, with an option to weigh the empty spool
  • Drying log with date and time
  • Assign to a printer and put back into storage, including a "needs reweighing" state
  • Bulk label printing, deletion and archiving via long press

Refills and empty spools

  • Empty spools tracked with tare, label and manual ID
  • Loose refills tracked as separate stock
  • Load a refill onto a spool from either direction
  • Pair by scanning: scan one half, then the other, and the app joins them
  • Tare gets more accurate every time a spool is emptied and weighed
  • Calculated savings compared with buying spooled filament
  • Filament cannot be unloaded from a single-use spool until you mark it reusable

Identification: QR codes and manual IDs

  • QR labels for spools, refills and printers
  • Print through the system print service or export to PNG
  • Empty spools always get the tare printed on the label
  • A "label does not match contents" flag after a refill swap
  • Manual IDs for people without a label printer — a letter and number, A1 to Z299
  • Automatic assignment of free IDs, or type your own
  • Duplicate checking across spools and refills, including archived ones
  • Manual IDs read by the camera via OCR, with correction of common character mix-ups.

Handwriting does trip the OCR up now and then, which is why it needs five matching reads — it is a fallback for when you cannot print a QR label, not a better version of one

  • The same letter-and-number scheme works for labelling shelves and rows, even if you do print QR labels

Scanner

  • QR codes, EAN-13 and EAN-8
  • OCR for handwritten IDs
  • Target frame — codes outside it are ignored
  • Five matching reads required before an ID is committed
  • Scanning the EAN off the box stocks the spool with every parameter
  • Torch control and a home screen widget for quick scanning

Filament library

  • Hundreds of materials from dozens of manufacturers, pre-filled
  • Structure: product (brand, material, series, colour, density) → package (length, price, EAN, tare)
  • Several packages per material — 1 kg spool, 750 g spool, spool-less refill
  • One tap stocks exactly that package
  • Assign an EAN code to a package
  • Pre-filled empty-spool weights and average prices, so the calculator has real numbers to work with
  • A sample print photo for each filament, so you can see what the colour really looks like
  • Custom colour picking including multi-colour combinations

Printers

  • Catalogue of ready-made profiles (Prusa, Bambu Lab, Creality, Voron and others)
  • Farm mode for several printers — custom naming, colour and ordering
  • Electricity consumption tracked separately for PLA, PETG, ASA, PA, TPU and ABS
  • Wear cost per print or per hour
  • Overview of which spool is on which printer
  • Maintenance log with intervals and reminders
  • QR labels for printers

Calculator

Pricing

  • Multiple materials in one print
  • Material from a specific spool in stock, from the library, or entered manually
  • Electricity cost from printer draw and print time
  • Depreciation per print or per hour
  • Post-processing at your own hourly rate
  • Failure rate in percent, other costs, markup and discount
  • Quantity and price per unit
  • Full cost breakdown before the final price

Finishing and history

  • Save a calculation as a project with a photo
  • Finishing a print subtracts material from the real spools
  • Sell for a different price than suggested — the app remembers both
  • Every completed print is logged with its breakdown and net income
  • Each record stores the currency it was created in

Statistics

  • Period: all time / month / year / custom range
  • Stock: item count, total weight, consumption, average price per kg, shelf value
  • Money: material, electricity, wear, labour, other, discounts, order value, net income
  • Library: manufacturers, material types, filaments, printers
  • Refills: reusable spools, free spools, loose refills, share of consumption, savings
  • Monthly consumption chart, material share and top 5 filaments
  • A warning when currencies are mixed within the selected period

Reminders

  • Running low, with your own threshold in grams
  • Separate thresholds for the five most used materials
  • Spools left out for too long, desiccant checks, printer maintenance intervals
  • Everything runs in the background, even with the app closed

Backups, export and sharing

  • Full backup to a JSON file
  • Partial export: stock, filaments or printers separately
  • Share via Drive, email or any app
  • Automatic background backup keeping the last seven files
  • Restore from an automatic backup by date
  • A corrupted or foreign JSON file is rejected with an explanation
  • Preview of the file's contents before import, and conflicts resolved item by item
  • Partial exports are made to be passed on: the filament library and printer profiles

can be swapped between people and built up together, with no server in the middle

Currencies

  • CZK, USD, EUR or a custom symbol
  • Currency chosen in the setup wizard
  • Switch currency at any time, confirming the rate with a preview of the conversion
  • Converts library, stock, printers, projects, calculator, electricity and labour rates
  • Print history is deliberately not converted — it is a record of what happened

Other

  • English and Czech
  • Light and dark theme
  • Setup wizard on first launch
  • Full manual and FAQ inside the app
  • Data consistency check after every change
  • Fully offline, no account, no cloud
