MarkerScan vs Cadrio3D
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
MarkerScan
This app allows users to measure 3D points in the real world using printed markers. Capture images and calculate 3D models, which can then be exported in various formats for further use, such as 3D printing or precise distance measurements.
- Measure real-world 3D points
- Use printed markers for accuracy
- Calculate 3D models from images
- Export models in .ply, .dxf, .xyz, .xls formats
- Quickly measure complex shapes
- Order 3D models for free

This app enables you to accurately measure points in the real world by downloading and printing a PDF file available on our website (http://markerscanapp.markerscan.com/en/Home/MarkerSets). Place the markers in such a way that they point towards 3D position you want to measure. Then follow the steps in the app (which includes taking pictures) to actually calculate the 3D points. After the 3D model has been calculated, you can decide to order it (currently for free). It will then be send to your email in different formats, such as .ply, .dxf, .xyz and .xls. You can use these files to get the exact distance between points, use it as a base for 3D printing and so on. Measuring shapes using this app is much quicker when you want to measure complex shapes such as curved walls, window sills and kitchen countertops.

Verdict
The clearest difference is in-app purchases: MarkerScan at none against Cadrio3D's 3. MarkerScan also leads on iOS requirement (8.1 vs 26.2). Cadrio3D's advantage is update cadence (every 9 days vs every 4 months). On price, ads and device support there is nothing between them.
