Easy3D Capture Support

Last updated: October 31, 2026

Easy3D Capture is an iPhone-only face and object capture app. The current application target requires iOS 27. Both Object and Face modes use rear-camera photogrammetry. Availability depends on the physical iPhone supporting native Object Capture and reconstruction; the app checks both capabilities. Front-camera and Gaussian capture are no longer available. Simulator samples exercise software only. Clinical accuracy and actual exocad interoperability require independent validation; facial capture does not replace an intraoral scanner.

Development status

Development is paused as of October 31, 2026, with no scheduled update or restart date. These instructions, privacy information and the contact address remain available. Pausing development does not remove scans from your iPhone. Export any scans you need before deleting the app; its private storage is excluded from system backups, and the developer cannot recover lost local files.

Release coverage

This page describes version 1.0 (13), submitted for App Review on October 14, 2026. Build 13 includes optional photograph retention, interrupted-reconstruction retry, unsaved-capture recovery, renaming, thumbnails, model extent, a privacy cover, export corrections and case-label exclusion from exports. Version 1.0 (13) is available in the US App Store, verified against App Store Connect and the public listing on October 31, 2026. Check your installed app’s version/build when applying these instructions. The earlier App Store submission 1.0 (12), built from 495b345, does not include those changes and includes case labels in export manifests, as disclosed below. Earlier development copies may also report 1.0 (12) while using newer source; record their source commit when reporting a problem.

Languages

The bundled interface supports English, Spanish, French, German, Italian, Brazilian Portuguese, Simplified Chinese, Traditional Chinese, Japanese, Korean, Hindi, Arabic, Indonesian, Turkish, and Vietnamese. Russian is not bundled. Substantial clinical, capture, safety and privacy guidance intentionally remains in English while translation review is pending. This includes many public guide passages, even when navigation and selected instructions appear in your preferred language. English is the primary language; translations may be inaccurate. The Privacy and storage view includes this notice. The app follows your system’s preferred supported language or the standard per-app language setting, then falls back to English when no supported preference is available. Relaunch after changing the language. Brazilian Portuguese uses pt-BR; Traditional and Simplified Chinese have separate resources.

Translations are included with the app and work offline. There is no translation account, translation permission, model download, or runtime translation service. Changing the interface language does not translate patient-entered text, saved names, custom labels, or imported records. Arabic uses the system’s right-to-left layout. Technical identifiers, file formats, units, and stored data contracts retain their original meanings.

When reporting a language or layout problem, include the app version, platform, interface language, text size, and the exact label or view. Use fictional data in screenshots. Spoken Siri availability and recognition depend on Apple’s supported languages and device settings.

Contact Sansar Gupta at sansargupta10@gmail.com. Include the app version/build, iPhone model, iOS version, selected subject (Object or Face), interface language and steps to reproduce. Do not include patient names, identifying case labels, facial images, scan models, or clinical records in ordinary email or public issues.

Capture and review

Open New scan, choose Object or Face, and follow the rear-camera guidance. Keep the subject stationary, use diffuse even lighting, and capture overlapping views. Aim for at least 70 percent overlap, fill the frame and take closer views for detail. For an object, move around its accessible sides, add passes at three heights, and use Review coverage between passes to inspect the point cloud and shot positions. A rigid, textured object can be flipped between passes with Flip object; keep it stationary during each pass. For a face, obtain informed consent, hold the chosen facial/jaw position still, and follow the front and side facial arc. Use a non-identifying case label; a facial model can itself identify a patient.

In build 13, reconstruction shows a time-remaining estimate when the framework supplies one. If the app moves to the background, the device reaches critical thermal state or reconstruction fails after photography has finished, the capture screen keeps the photographs and offers Resume building. Let the device cool and free at least 2 GB if the app asks, then resume while keeping the app open. This retry is available from that capture screen; it does not restore an unfinished reconstruction after the app has been closed. If the finished model fails the mesh-conversion check, choose to build it again, keep it for USDZ export only or discard it. A USDZ-only model retains its conversion warning; an opted-in photo set can still be exported. Interruptions during photography discard the unfinished capture instead.

For a stalled capture, use Share diagnostics in the capture toolbar before restarting. When a capture fails, the failure screen also has a Share diagnostics button. You review and choose the destination in the system share sheet. The diagnostic report contains app version/build, iPhone model and iOS version, timing and photograph counts, capture settings, readiness, processing and thermal state, and recent diagnostic events. It excludes photographs, models, case labels and file paths. It is not sent automatically.

When cancelling, confirm Discard capture during capture, Stop and discard while the model is building, or Discard photographs when the photographs were kept after an interrupted build or a failed OBJ, PLY and STL conversion check, and wait for the unfinished capture to be removed. The capture screen stays open while camera/reconstruction writers stop and files are removed. If removal fails, unlock the iPhone, check available storage and retry using the capture screen. An error means the app has retained the unfinished files for cleanup; it does not mean they were deleted. Avoid deleting the app unless you have exported every saved scan you need.

Both modes reconstruct textured surfaces locally. Inspect coverage, holes, textures, orientation and known physical dimensions independently before using geometry in a CAD workflow. Photograph counts and capture progress do not establish accuracy. A face is particularly sensitive to motion and reflective eyes or teeth.

Storage, export and deletion

Scans are saved in private, protected on-device storage. The app has no patient account, cloud reconstruction service or automatic upload. New photogrammetry captures remove reconstruction checkpoints after a completed model is validated. They also remove the source photographs unless you turn on Keep photographs for Mac reconstruction for that capture (build 13; see below). In build 13, if building stops after capture has finished, or the model cannot be converted to OBJ, PLY or STL, the photographs stay on the device so you can resume building without capturing again. They are removed when you discard them, start a new capture, leave the capture screen or keep the model (unless you chose to keep them for Mac reconstruction); if the app is closed first, the abandoned-folder cleanup removes them later. Saved models retain photographic textures and geometry that can identify a person. Older records from retired capture modes remain readable; any source data already associated with them remains local until deletion.

Open a saved scan, choose an available export format, and choose a destination in the share sheet. CAD mesh exports use millimetres. Legacy splat files, if present in an older record, remain exportable in metres for an external compatible viewer; the app no longer renders splats. Verify the receiving application’s units and anatomical left/right orientation. Formats do not enforce units.

In build 13, the scan's review shows its Export ID (for example FaceScan-1A2B3C4D), which the exported ZIP or USDZ file name starts with, so you can match a shared file to a library entry; library search also finds a scan by at least four characters of the ID after FaceScan-. The review also shows the Model extent, the size of the model's bounding box along its own axes in the millimetres used for export. It is not a verified measurement; check dimensions against a known physical reference. If the app cannot confirm the model's scale, the size is shown as unavailable.

An OBJ, PLY or STL export is a ZIP whose name is built from a random scan ID. It contains the model file and any required material and texture images, READ-ME.txt with units and handling notes, and scan-manifest.json with technical details: scan ID, capture mode and subject, the date and time the scan was saved, iPhone model identifier, iOS version, units, coordinate system, vertex and triangle counts, capture-quality counts and warnings, scale status, and internal format fields. An original USDZ export is the unchanged reconstructed model file, also named from the scan ID. Build 13 keeps the case label in the library on your iPhone and does not write it into exported files or file names. The earlier submitted version 1.0 (12) and earlier distributed builds include the label as the name value in scan-manifest.json and splat-manifest.json; review or delete those copies if needed. Earlier development copies may report 1.0 (12) while using newer source, so retain their source commit to identify their export behavior.

Build 13 also removes a temporary export after a swiped-away share sheet, allowing a 60-second grace period. Interrupted cleanup is retried for eligible temporary folders older than 24 hours during a later library opening. Recent or unreadable files may be retained, so this is not a fixed retention deadline.

In build 13, you can correct a label: open the scan and choose Scan actions → Rename scan…, and use a non-identifying reference. Library rows also show a small preview of each model, created and stored on the device with that scan; previews are never exported and are deleted with the scan.

Open a scan, choose Scan actions → Delete scan, and confirm to remove its saved model and capture data. In build 13, you can also touch and hold a scan in the library and choose Delete scan. Copies already exported to Files, other apps or recipients must be removed separately. Private scan storage is excluded from system backups; export the needed files before removing the app. The developer cannot recover locally lost scans.

In build 13, a reconstruction that finished but was not yet saved is kept in the protected library on your iPhone, without its case label, until you save or discard it. If saving fails or the app closes first, open the library: the capture appears under Unsaved captures with Save to library (you can enter the optional label again) and Discard (asks for confirmation). Unsaved captures that cannot be opened are reported and their files kept until you choose Discard damaged captures there (asks for confirmation) or remove the app. A capture whose save completed before the app closed is not offered again.

If the app closes during saving, a completed local save may be restored automatically when the library opens after at least 24 hours. Recently modified, incomplete, damaged or conflicting saves are preserved rather than replacing an existing scan. If the library reports files it could not open, include the error wording and reproduction steps in a support request; do not email private scan files. This recovery cannot restore files removed from the device.

Rebuild at higher detail on a Mac

Build 13 adds an opt-in photo set. Before opening the camera, turn on Keep photographs for Mac reconstruction. It is off for every new capture and is not remembered. With it on, the capture needs at least 5 GB of free storage, and the photographs are saved with the scan in the protected, backup-excluded library instead of being removed. The review screen then shows Photographs kept and offers Photo set for Mac (ZIP). The app asks you to confirm before each photo-set export.

The ZIP is named from the scan ID (for example FaceScan-1A2B3C4D-photos.zip). It contains every kept file the capture wrote, under its original generated name, photo-set-manifest.json with technical scan details, photograph count, total file size and generated file names (never the case label), and READ-ME.txt. The photographs are full resolution and show the subject, the background and anyone else in view. Object Capture photographs can embed depth data, camera poses, capture time and the device model. Treat the set as identifiable data.

A photo set must fit the supported limits: at most 2,000 files, 3.5 GB total and 200 MB per file, without nested folders or links. If it cannot be kept, the model is retained with a warning and no photo set. Check Photographs kept and the warnings before relying on a later Mac rebuild. Preparing the ZIP also needs free space for another copy of the set plus approximately 100 MB.

On a Mac with a GPU that has at least 4 GB of memory and ray-tracing support, unzip the set into one folder and import it into Object Capture in Reality Composer Pro, or use PhotogrammetrySession, at Full detail with unordered ordering. The iPhone builds only reduced detail (under 50,000 triangles, 2048-pixel textures); Full allows under 250,000 triangles and 8192-pixel textures. That is higher mesh and texture resolution, not demonstrated higher accuracy. Mac output is in metres; multiply by 1000 for millimetres, and check an independent known distance. Mac results are outside the app's millimetre exporter, scale check and label redaction.

To remove kept photographs, open the scan and choose Scan actions → Delete photographs; the model and its other exports stay available. Delete scan and removing the app also remove them. Copies you exported are separate and must be deleted where you shared them. Scan content leaves the iPhone only when you choose to share it. The developer receives no automatic scan upload; the last recorded App Store privacy disclosure is Data Not Collected.

Privacy

Read the in-app Privacy and storage view and the privacy policy. In build 13, that view links to the privacy policy and this support page, which open in your web browser, and a cover hides the screen when you leave the app so the App Switcher does not show scans or labels. Only public capture guides are exposed to Siri and Spotlight. Patient scans, case labels, images and geometry are excluded. Language resources are bundled; private scan content is never submitted to a translation service.
