The professional aPrehliadky companion: recomputes an iPhone frame package into a higher-detail 3D model directly on an Apple Silicon Mac and issues a report with a chain of evidence. No cloud, no upload, no subscription.
The aPrehliadky app for iPhone and iPad can capture and reconstruct a 3D model directly on the device, but only on iPhones with LiDAR and an A17 Pro chip or newer, since Apple's iOS photogrammetry layer (CorePhotogrammetry) does not run on older devices or on a Mac. Fotograme3ka 3D is therefore a standalone, native macOS application that processes the same frame package through a native macOS photogrammetry framework: at a level of detail beyond what the iPhone itself can achieve.
A typical use case: an older iPhone without LiDAR, or without a sufficiently capable chip, can still capture in aPrehliadky, but cannot compute a model. The frame package is sent over AirDrop to a Mac, recomputed there, and the finished model returns to the iPhone as an .f3d package, including any findings and measurements carried over from the earlier model to the new one.
The iPhone computes the model only at low detail. The Mac offers medium, full and custom detail (a polygon cap, texture up to 16,384 px): a 3 to 5 times finer surface for measuring findings.
The Mac uses up to 1,500 frames; the iPhone captures up to 600 but computes from 200 (an Apple limit). Several packages dropped at once are processed in a batch, one after another.
The app's second tab offers full-featured work with the finished model: orbit, zoom, measurement, findings marked directly on the skin, and a PDF report with certificate.
After each recompute, camera poses are stored; on the next recompute they are fitted for yaw, scale and offset, and findings are carried over to the new model with an error on the order of millimetres.
Processing presets Fast, Forensic (300,000 triangles, 8K texture, lossless; recommended) and Maximum (1 million triangles, 16K). Blurred frames are dropped, frames showing the target are kept.
A SHA-256 of every file, input verification before processing, a reconstruction record in the package and the report, and signing of the output package with this Mac's key. A PDF/A-2b report and a class A to D certificate.
| Platform | macOS 15+, Apple Silicon (M1 and later) |
| Frame limit | up to 1,500 (iPhone: captures up to 600, computes from 200) |
| Texture | up to 16,384 px, custom polygon cap |
| Network | none: App Sandbox, only the Open/Save panel |
| Price | €34.99 one-time (US$29.99), no subscription; aPrehliadky for iPhone is free |
Fotograme3ka 3D runs inside the App Sandbox with no networking layer whatsoever: it can only access files you explicitly choose through the system Open/Save panel. The app never transmits models, images or reports anywhere; the only way data leaves the Mac is AirDrop or a file export you initiate yourself.
The aPrehliadky app for iPhone and iPad remains free, so that anyone can try and use 3D documentation of an examination. Fotograme3ka 3D is a professional tool for departments that need the highest model detail, examination on a large screen and a report with a chain of evidence. From 18 October 2026 it costs €34.99 (US$29.99) as a one-time purchase, no subscription, no ads and no data collection.
Apple's photogrammetry changes between macOS and iOS releases. Your purchase pays for quick fixes with every new system version and for new features in Fotograme3ka and aPrehliadky.
Measurements on reference standards, the T3 calibration target, the A–D certification methodology and its revisions: the work that gives every measurement a stated uncertainty and a report that stands up to scrutiny.
The project has no ads, no investors and sells no data. Sales of the professional tools keep the free apps alive as well: aPrehliadky, 4n6 Tools Lite, littlEye AI and Congressa.
The apps are built alongside the practice of a forensic pathologist. The author answers you directly, and feedback from practice goes into the next versions.
For a fraction of the price of typical professional photogrammetry software you get a tool built specifically for forensic medicine and death investigation: an uncertainty with every measurement, a signed package and a PDF/A report.
Not necessarily. An iPhone with LiDAR and an A17 Pro chip or newer computes the model directly in aPrehliadky. Fotograme3ka 3D is useful when you want higher model detail (medium or full, a 3 to 5 times finer surface), or when you are capturing on an older iPhone without LiDAR or without a sufficiently capable chip.
Via AirDrop. You export the frame package from aPrehliadky, open it in Fotograme3ka 3D on the Mac, the app recomputes it, and the finished model, including transferred findings and measurements, returns to the iPhone again as an .f3d package.
Up to 1,500 frames and textures up to 16,384 px. The iPhone captures up to 600 frames but computes the on-phone model from the best 200 only (an Apple limit) with textures up to 8,192 px. Several packages dropped at once are processed in a batch, one after another.
Yes. Since 18 October 2026 it costs €34.99 (US$29.99) as a one-time purchase, with no subscription and no ads. The aPrehliadky app for iPhone and iPad remains free. Fotograme3ka 3D requires a Mac with an Apple Silicon chip and macOS 15 or later.
aPrehliadky should be available to anyone who wants to try and use 3D documentation. Fotograme3ka 3D is a professional tool for departments that need the highest detail and a report with a chain of evidence. Its sales fund the development of both apps, accuracy validation, maintenance for new macOS and iOS releases and the running of the independent forensika.eu project.
No. If you downloaded Fotograme3ka 3D before 18 October 2026, it stays yours, including all future updates. On a new Mac, simply download it again from the Mac App Store with the same Apple ID.
