## What is Schama?

Schama organizes your 3D file collection, 3D printing, modeling, scans, right on your iPhone and iPad, without ever duplicating your files unless you ask it to.

WHY SCHAMA
Whether you print in 3D, model, or archive scans, your .stl, .3mf, .usdz, .obj and other files end up scattered across Files, iCloud Drive, and download folders. Schama brings them together in a single, searchable, organized catalog, without ever locking your files into a closed silo. They stay right where they are; Schama simply references them.

KEY FEATURES

Flexible import
• Import one or several files, or an entire folder scanned automatically with all its subfolders
• Choose the destination library at import time, or create a new one on the spot
• Recognized formats: USDZ, STL, OBJ, PLY, FBX, DAE (Collada), ABC (Alembic), 3MF

Interactive 3D preview
• Touch rotation and zoom for STL, USDZ and 3MF files
• Full-screen mode with wireframe display, handy for checking geometry before printing
• Thumbnails generated automatically on import
• 3D preview of 3MF and STL files right in the Files app, with dimensions, volume and estimated weight

Organize your way
• Custom libraries with your choice of icon
• Colored tags, assignable by drag-and-drop or created on the fly
• Instant search by name, notes, or tags
• Automatic detection of files whose original has been moved or deleted

Print tracking
• Print history per file: printer, filament, quality rating, date
• Overall rating and favorite status to find your best models again

Smart summary, entirely on-device
• A description of each model is generated by Apple's on-device intelligence from its preview, no data is ever sent to a server

iCloud sync
• Your catalog, libraries, tags, and print history sync automatically across your devices through your personal iCloud account
• Optionally duplicate a file to an iCloud Drive folder of your choice, making it available on your other devices without touching the original

Share and back up
• Send an object's source file via AirDrop, Mail, or any other method right from its detail page
• Full catalog export (JSON) or CSV export
• Automatic daily backup of your catalog to the folder of your choice; restoring adds what's missing without deleting anything
• Siri and Shortcuts: search, open or convert an item, log a print, create a library, or import a folder by voice

A BUILT-IN HANDBOOK
A complete guide, chapter by chapter, to read in the app at any time, even offline.

BUILT FOR IPHONE AND IPAD
An interface tailored to each device, grid view and column navigation on iPad, tab navigation on iPhone, for a smooth experience on any screen.

Schama requires no account, tracks no activity, and collects no personal data beyond what's strictly necessary to sync through your own iCloud account.

## Version history (last 5 releases)

### 2.2.1 — 2026-10-17

3MF models appear in the 3D preview again. Since 2.2.0, some showed only their bounding box, and the app could quit when opening them.

A 3MF file prepared in a slicer such as Bambu Studio keeps the size you gave it, and an object printed several times appears that many times. Dimensions, surface area and volume are now correct.

In the Files app, the preview of a multi-part 3MF no longer shows duplicate objects.

### 2.2.0 — 2026-10-14

A new welcome screen introduces Schama in four pages: what the app does, where your data goes (iCloud, backup folder, privacy), creating a first library from a folder, and the handbook.

An item's details now match the Mac: File, Source, Print and 3MF or STL tabs, detailed geometry (volume, surface area, triangles, watertightness), tags and comments edited in place, object identification and a description written on device.

On iPad, the columns step aside when you open an item to give it the whole screen; swipe right to bring them back.

Choose the appearance in Settings: Light, Dark or System.

Large STL and 3MF files open with less memory, the 3D preview can be controlled with VoiceOver, and file types are translated in the Files app.

### 2.1.0 — 2026-10-10

Schama now backs up your catalog every day: entries, libraries, tags, prints and thumbnails, in the folder of your choice. Your 3D files stay where they are. A copy is also made before every group deletion, before the examples are removed and before a folder is imported. In Settings, the Backups section lists your copies; restoring one adds what is missing, without deleting anything.

On iPad, Schama makes the most of the large screen: the system sidebar, menus and keyboard shortcuts, drag and drop of items onto a library, and any item can open in its own window.

On iPhone, search has its own tab, importing starts from the Catalog, and a swipe adds a favorite or deletes an item. The Libraries tab also gathers file types and files to check.

Every item now has a full menu: favorite, share, add to a library, delete. Your actions can be undone (shake, or ⌘Z with a keyboard), and Schama asks before removing an iCloud copy or discarding changes. Settings are reorganized into sections.

A Favorites list gathers the items you've marked as favorites, and the catalog can now also be sorted by tags.

A built-in handbook explains Schama step by step, even offline: it opens from the welcome screen, then at any time from Settings (and the Help menu on iPad).

In the Files app, 3MF and STL models now have a 3D preview with their dimensions, volume and estimated weight, and "Open in Schama" adds them to the catalog.

Siri and Shortcuts actions are translated into every language, and two new actions convert an item or return its details.

STL dimensions are in real millimeters, the 3D preview shows the whole item, a print can be edited from the item page, and the app stays readable at the largest text sizes and with VoiceOver.

3MF models now display with sharp edges, like STL files, and fill the preview on their item page, with their dimensions and measuring tools.

### 1.2.0 — 2026-09-08

The example models can now be removed in a single action, from Settings. They do not come back on the next launch.

That removal only touches the files Schama installed. A model you had imported yourself under the same name, a 3DBenchy for instance, could disappear from the catalog along with them. It no longer can.

Examples no longer duplicate themselves from one device to another when the catalog syncs through iCloud.

The Licences screen, in About, lists the licences of the components and models shipped with the app.

Under the hood, Schama has moved to Swift 6 with strict concurrency, groundwork that rules out a whole family of concurrent access errors.

### 1.1.9 — 2026-09-04

No release notes.
