Thanks to this application (and the other Widget apps from PacoLabs), you can now customize the Home screen and the Today view of your device, by adding custom widgets for some specific purposes. From anywhere in your device, you'll have access to your own information and actions. Each RSS widget allows you to view any RSS feed in a pleasant and highly customizable way. The refresh frequency can be chosen (from every 5 minutes to every day). You can choose to display the content as a beautiful image with an overlayed text, or as an article with an icon, and the associated text. Articles without an image can be filtered. You can define the number of articles to display in a single widget (from 1 to 6). If necessary, you can also choose the first article to be displayed. Decide to hide or show the image, title, abstract, content and author. Different visual parameters can be changed (such as font name, font size and the different colors). Those Widgets are compatible with the new iOS 14 Home Screen Widgets. The application is really easy to use and is adapted to the fresh look of your device. Dark mode of iOS13 is supported. In Today view: You can add as many widgets as you want and they will be displayed in up to 3 different lists. Those same lists will be available in the Today view and in the application (although it is possible, if you want, to hide some widgets in the Today view). To avoid overloading the Today view, when too many widgets are displayed, an intuitive control will allow you to navigate from one widget to another. Even if the main purpose of the app is to view the widgets in the Today view, it can also be very handy to view them directly in the application (a long press on a widget in the Today view will open it directly in the main application).

Scan4D is a professional-grade reality capture app for iPhone and iPad. It turns your device's LiDAR sensor and camera into a powerful 3D scanner, capturing detailed meshes, depth maps, and camera poses for downstream reconstruction, photogrammetry, and spatial computing. FULL MODE (LiDAR devices) • Real-time mesh reconstruction with live wireframe overlay • 16-bit depth maps captured at adaptive frame rates • Scan capacity metrics: polygon count, drift tracking, session duration • Interactive 3D mesh preview with camera-sampled vertex coloring • Privacy filtering: person segmentation removes humans from meshes, face blurring in RGB exports LITE MODE (all devices) • RGB frame capture with ARKit camera poses • Server-side photogrammetry via exported image bundles • Automatic detection — no configuration needed TIME-SERIES SCANNING • Group scans by Location and re-scan the same space over time • "Extend Scan" loads a red ghost-mesh overlay of previous captures • Adjacent stitching: scan neighboring areas with shared coordinate frames • ARWorldMap relocalization for precise alignment between sessions FLEXIBLE EXPORT FORMATS • Scan4D: Full bundle with metadata, relocalization map, images, depth, and camera data • Polycam: Raw data import compatible with Polycam • RAW: Nerfstudio/COLMAP-compatible transforms.json + images + depth • OBJ / PLY / USDZ: Native mesh formats for MeshLab, Blender, and iOS Quick Look SERVER INTEGRATION • Configure any HTTP(S) upload endpoint in Settings • Direct PUT upload with live progress tracking • Save to Files or AirDrop for offline workflows • Compatible with self-hosted reconstruction pipelines DEVELOPER MODE • Front/back camera switching for testing privacy features • Synthetic IMU, camera, and depth injection for Simulator testing • Vertex mapping diagnostics and debug overlays Designed for researchers, 3D scanning professionals, and spatial computing developers who need raw, high-fidelity sensor data with full control over the reconstruction pipeline. Requires ARKit-capable device. LiDAR-equipped iPhone or iPad Pro recommended for full functionality.

Verdict
The clearest difference is price: Scan4D at Free against RSS Widget's $0.99. RSS Widget's advantage is iOS requirement (12.0 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
