TKI NET Scan
Precise 3D Scans for Build
Free
With the NET Scan App, network operators, construction supervisors, and construction crews can create, store, and edit highly precise 3D scans. The app uses advanced technology and connects to an external GNSS receiver to provide exact geo-positioning of the scans. This enables highly accurate project documentation.
Features:
- Exact geo-positioning with an accuracy of up to 1 cm via GNSS receiver.
- Create 3D scans with the ability to add photos, point, and line objects.
- Edit and organize scans directly in the app.
- Secure storage and management of data in NET Cloud.
- Intuitive user interface with map view and easy navigation.
The NET Scan App is easy to use, highly flexible, and ensures maximum efficiency and precision in your construction projects.
more - Continuous scanning: Capture multiple consecutive scans within a single scan session. This makes it easier to scan longer areas without unnecessary gaps and reuse existing markups in the next scan.
- AI photo analysis notices: Users are now informed before capturing or importing photos when AI-based analysis is used. Detection masks also include a notice that AI-generated results may not always be accurate.
Improvements
- Easier login: Parts of the NET Cloud server address are now completed automatically.
- Last server address saved: The most recently used NET Cloud instance is retained after logout and suggested again at the next login.
- Warning for scans without markups: NET Scan can now warn users when saving a scan that does not contain any markups.
- Direct navigation to missing information: If a scan cannot be uploaded because layers, required attributes, or photo tags are missing, the app now takes you directly to the affected section.
- Improved upload and processing status: Status indicators no longer cover important map controls.
- Default titles for scan photos: Uploaded photos automatically use the associated address as their default title.
- Synchronized markups: Connected or snapped markups across scans within the same scan session are now synchronized consistently.
Bug Fixes
- Improved feedback when location access is disabled.
- Improved guidance when the second manual positioning point is missing at the maximum scan size.
- Empty photo titles and descriptions no longer display "Type here" as actual content.
- Selected object types can once again be removed or deselected in markup details.
- Added a confirmation prompt to prevent accidental loss of project photos.
- Fixed a crash that could occur when opening photos in full-screen mode.
- Fixed the scan quality indicator help display on iOS 18.1.1.
- Fixed the display of nested multi-select fields.
1.2.18 Sep 4
- Scan upload in and presentation of projects with grouped duct types works correctly again
1.2.17 Aug 6
Version 1.2.16 focuses on performance and stability: scan restoration after tracking loss is improved, and scans now process faster. The update also adds a small number of new features and resolves several bugs.
New Features
- Add title and description in the photo preview — When taking a photo, a title and description can now be entered directly in the preview — without having to open the details page afterwards.
Improvements & Optimizations
- Scanning performance optimization — improved app restoration from tracking lost state.
- Processing optimizations — scans are processing a bit faster now.
- GNSS battery warning — A warning is now shown before starting a scan when the connected GNSS device's battery is below 20%.
- Warning for flagged devices — When connecting to a known problematic device, the app shows a warning and directs the user to contact support.
- Overhauled scan UI for portrait mode (iPad) — The scan interface in portrait mode has been optimized for iPad use: buttons are now easier to reach without repositioning hands.
- Single points displayed above route points again — Points placed on a line are now correctly rendered above the route points.
- Automatic timestamp naming for photos — Photos in scans are automatically named with a timestamp when no custom title has been assigned.
- Button placement — Confirm button in markup details is now placed beside the delete button
Bug Fixes
- Placing a point outside of its allowed range is no longer possible, out-of-range distance is being indicated correctly again
- When opening NETScan from Deeplink, the processing screen remains readable in light mode
- Fixed issue where two project with shared name and ID had the app open the wrong project on launch
- Switching scans from unavailable project into an available project is now working consistently
- Overlays on photo refresh correctly when deleting points/lines
1.2.16 Jul 29
Release Notes 1.2.15:
New Features
- A visual quality indicator now shows in real time how well the environment is being captured during scanning: in difficult conditions such as low-contrast surfaces, users can adjust their scanning behaviour right away
- RTK positioning can now be skipped when adding a photo: no waiting for a fix when the photo doesn't need a precise position
- Photos now display the points and lines placed during the scan as an overlay, so markups are visible directly in the photo view of the job list
- Deleting points or lines during scanning now shows a confirmation prompt, preventing accidental removal
Improvements & Optimizations
- If the app loses tracking during a scan, it now guides you through getting it back: return to an area you've already scanned and point the camera at the same view as before. Once tracking is restored, the scan stays correctly aligned, with no duplicate or shifted paths, even on large scans
- The "Hold device upright" overlay now appears only after a short delay: brief tilts while placing points (e.g. at ground level or in a pit) no longer trigger it immediately
- Object highlighting and selection during scanning has been reworked: highlighted objects are now clearly distinct from the object colour, and the selected object stays unambiguously in focus while editing
- Messages about missing location data are now action-oriented
- The "Comment" field is now called "Description": consistent naming with NET Cloud
Bug Fixes
- AR GeoLock no longer interrupts the scan when moving during reference-point selection
- Changes to a title or description are now saved even when leaving the view directly via the back button
- Dropdown selections when editing points and lines are now reliably applied on the first tap (iPhone and iPad)
- The line type now updates immediately when changed during a scan
- When an error occurs in manual positioning mode, the map and adding points remain available
- After relocalisation, the scan no longer appears rotated and is placed at the correct position again after processing
- Starting a new scan while others are still processing no longer makes the app appear frozen
- The project selector frame is displayed consistently again after switching between projects
- All materials in the markup details can now be scrolled through, even after a scan has been uploaded
- Fixed crashes and freezes when opening scan details
- Scan processing is more reliable: scans no longer fail during processing, and previously empty or failed scans now complete correctly
1.2.15 Jun 18
Release Notes 1.2.14:
- Post-processing mesh correction now aligns scans against RTK anchors on the vertical axis as well, not only horizontally: longer scans deliver reliable altitude values even when ARKit Z-drift accumulates over the scan duration

- Line markups now show the 2D (horizontal projection) length alongside the 3D length — useful for billing workflows that reference planimetric distances
- During scanning, receiver tilt is now monitored and shown visually — for better positional accuracy and more precise altitude values
- Scan altitude accuracy has been significantly improved: refined filtering of the reference points used to position the scan keeps unsuitable samples out of the result
- The photo icon in the scan list now counts every photo, including those captured with line or point markups, so the number no longer changes after processing
- The tag selection box no longer disappears when all suggested tags have been selected — tags can still be edited or removed
