What this is
A place to keep your 3D printing straight: what you are printing and who for, how much filament is left, and which models have earned their keep. It runs entirely on this device.
What it is not
- It is not a slicer and it does not talk to your printer. The printer field is just a note to yourself.
- It is not tied to any brand, so nothing here breaks when you change machines.
- There is no account, no sync and no server. Nothing you type is sent anywhere, and nobody else can see it — including whoever made this.
- It is not a backup. The data lives in this browser's storage, and clearing site data for this site removes it. Export a copy somewhere safe.
How the filament number works
A spool's remaining weight is never typed in. It is the spool's total minus every gram you have logged against a job, worked out fresh each time you look. Log the grams on the job, and the inventory follows.
Put it on your home screen
- iPhone and iPad, in Safari: press Share, then Add to Home Screen.
- Android, in Chrome: press the three-dot menu, then Add to Home screen or Install app.
- Windows or macOS, in Chrome or Edge: open the three-dot menu, then Cast, save and share or Apps, then Install this page as an app.
- macOS, in Safari: open the File menu, then Add to Dock.
Once it is there it opens like any other app and works with no signal.
What changed
Where the numbers come from
All of them come from you. This app fetches nothing, ships with no dataset, and contacts no service — so there is no feed to credit and nothing to go out of date behind your back. Every figure on screen is either something you typed or arithmetic on it.
Your safety copies
Before any import replaces your data, the app saves a copy of what is already here — both as a download and inside the app. The most recent are below.
How to report a problem
Open the diagnostic report from the version number at the bottom of the screen, copy it, and send it with a note about what happened. It is plain text, it says what the app can see about this device and this build, and it contains nothing you have typed into the app.
