Features
One logbook for the whole bench
Inventory, cost, maintenance, and a journal, instead of five single-purpose apps or a brand-locked cloud.
Track filament
- A spool inventory with grams remaining and cost for every roll.
- One-tap "used 25 g", or scan a barcode or QR label to jump to the spool.
- Weigh-to-update: put the spool on a kitchen scale, type the reading, and Gyroid does the tare math (the core weight is remembered, and can be saved by name to reuse on other spools).
- Low-filament flags so you reorder before a print fails on an empty spool.
- A storage location on every spool, and the inventory groupable by shelf or dry box, so you know which one to walk to.
- Printable QR spool labels: stick one on each roll and a scan opens that spool, from Gyroid or the Camera app.
- A reorder link per spool, offered at the moment it runs low. The link opens in your browser; nothing is sent anywhere.
- A run-out forecast on every spool ("about 6 prints left at your pace"), worked out from your own logged usage.
- Flag a spool "needs drying" and get a reminder before damp filament ruins a print.
- Presets for 15 filaments and 3 resins carry the densities behind every length and weight estimate.
- Resin mode for MSLA, tracked in milliliters.
Know the cost
- Filament + electricity + machine depreciation, added up for every print.
- Multi-material prints: log every spool an AMS or MMU print used, each charged at its own price, with power and wear counted once.
- Add labor, a failure allowance, and your margin for a suggested shop price.
- A standalone calculator, and a cost saved with every logged print.
- Note what a print sold for, and Bench stats turns cost into revenue, profit and margin, ranking the models worth printing again.
- A model-scaling calculator: resize a model and see the grams, length, and cost before you slice.
Stay maintained
- Nozzle, belt, lubrication, and lead-screw reminders by print-hours.
- Per-printer schedules: logging a print advances the clock automatically.
- A maintenance history that proves a machine is cared for.
Keep a journal
- Model, printer, filament used, the settings that worked, success or fail.
- A photo per print, a searchable history, and a photo wall of every shot in one grid.
- Saved profiles per printer and material so you never re-dial settings.
- Failure analysis: success rate by material and by printer, so the log becomes a diagnosis.
Learn at the bench
- 19 reference guides built into the app: first layers, stringing, warping, bed adhesion, nozzle temperatures, infill, materials, and maintenance.
- Grouped into Basics, Settings, Troubleshooting, Materials, and Maintenance, and searchable by keyword.
- Stored inside the app, so they open with no signal, mid-print.
- Written in English, French, German, Italian, Japanese, Portuguese, and Spanish. The app shows them in your language.
Log without typing
- Open a G-code or 3MF from Bambu Studio, PrusaSlicer, OrcaSlicer, or Cura and the entry pre-fills itself: name, time, grams, material.
- Siri & Shortcuts: log a print, check filament remaining, or start the print timer from a smart-plug automation.
- A print timer with a Live Activity. When it finishes, the alert opens the log already filled in.
- "Print it again" re-logs a repeat print with the same spool, printer, and settings.
On every screen
- Home-screen widgets: filament remaining per spool and the next maintenance due.
- Spotlight search: type "benchy" on the home screen, land on the log entry.
- An Apple Watch app: start, extend, or finish a print from your wrist, check spools and recent prints, plus watch-face complications for filament and maintenance.
- An on-deck print queue that checks each plan against what's left on the spool.
- A monthly bench recap of prints, filament, cost, and success rate, computed entirely on device.
- One app on iPhone and iPad, and on Apple silicon Macs and Apple Vision Pro.
For the whole bench
- Brand-agnostic: a Bambu, a Creality, and a resin machine side by side.
- Multiple printers with separate history and schedules.
- A full backup in one file: printers, spools, prints with photos, maintenance history, profiles, and the queue. Restoring adds to what is already there and never deletes anything.
- CSV export for Numbers, Excel, or your Etsy spreadsheet, and CSV import to bring an existing inventory in.
- Grams or ounces, and your own currency, throughout.
Private by design
- Works offline at the bench. No account, no OEM cloud login.
- Your data stays on your device and syncs through your own iCloud.
- Every alert maps to a real bench event, with per-alert switches and quiet hours. Nothing is marketing.
- One tap erases every printer, spool, print, and photo from the device and your iCloud.
- No ads, no tracking, no data sale.
