Outcrop vs Sketch Viewer UP
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Outcrop
This app aids geologists in field studies by allowing them to capture high-resolution images of outcrops. Users can interpret geological features, add annotations, take measurements, and export data to construct 3D geological models.
- High-resolution outcrop imaging
- Interpretation of facies, structures, and boundaries
- Annotation and measurement tools
- Dip and azimuth measurement
- GPS location integration
- 3D geological model export (GOCAD format)

This application is designed for the geologist to use during field studies. It lets the user take pictures of the outcrop, interpret the high resolution image and export this information in 3D to construct a 3D geological model. On the image, the user can interpret facies intervals, sedimentary structures and boundaries. The user can add annotations anywhere, measure width/height of sediment bodies (channels, lobes, etc.), and compute bodies statistics. Using an iphone or ipad, the user can measure dip and azimuth and locate this measure on the picture or use its GPS location to export dip markers to the 3D model. Once the user defines the image scale, all interpreted boundaries and intervals can be exported in 3D in GOCAD format (image, interpretations boundaries, dip/azimuth and facies intervals).
Sketch Viewer UP
This application allows users to import and view 3D models from various professional design software. It supports a wide range of file formats, making it convenient for designers, engineers, and students to access and analyze 3D drawings on their mobile devices.
- Import and view 3D drawings
- Supports multiple professional 3D file formats
- Collection of standard industry libraries
- Mobile 3D viewing software
- Professional CAD drawing and modeling

Verdict
The clearest difference is in-app purchases: Outcrop at none against Sketch Viewer UP's 3. Outcrop also leads on iOS requirement (11.0 vs 13.0). Sketch Viewer UP's advantage is update cadence (every 8 days vs every 5 weeks) and ratings volume (10 vs 3). On price, rating, review sentiment and ads there is nothing between them.
