Outcrop vs Mapboard GIS
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).
Mapboard GIS
This iPad app allows users to draw field maps using an Apple Pencil, combining the ease of pen-and-paper with the precision of GIS. It's designed for geologists and others needing interpretive mapping, offering intuitive tools for creating topologically consistent geologic maps.
- Pen-based editing tools
- Intuitive reshaping and snapping
- Iterative topology solver
- Onboard Spatialite GIS engine
- Native GIS software compatibility
- User-configurable data types
- Tether to remote PostGIS

Mapboard GIS is an iPad app for drawing maps with an Apple Pencil. Mapboard combines the intuitive workflow of pen-and-paper mapping with the precision, flexibility, and scale-independence of geospatial information systems (GIS). Its forward-looking design helps beginner and expert mappers produce multiscale, topologically consistent geologic maps. MOTIVATION AND DESIGN Mapboard GIS was born out of frustration with both paper– and GIS-based mapping workflows. It is primarily designed for geologists but is potentially useful in many situations demanding interpretive mapping. Mapboard attempts to bring digital mapping closer to the intuitive experience provided by paper. A sophisticated open-source spatial engine drives simple tools for drawing, erasing, and reshaping features. Outputs are natively compatible with common GIS software. Mapboard allows mapping time to be spent refining interpretations instead of fighting with technical tools. KEY FEATURES - Editing tools geared towards pen-based mapping - Powerful and intuitive reshaping, snapping, and erasing - Iterative topology solver to fill map units - Sophisticated onboard Spatialite GIS engine - Project files natively readable by standard GIS software (QGIS, ArcGIS, etc.) - User-configurable data types for line and polygon features - Tether to remote PostGIS for work across large datasets and real-time collaboration - Interoperable with standard formats (mbtiles, Spatialite, PostGIS) and open-source + commercial software OTHER FEATURES - Load MBTiles basemaps - Satellite, streets, and topographic basemaps - Dark mode support - Geologic line types TERMS OF USE: https://mapboard-gis.app/terms-of-service PRIVACY POLICY: https://mapboard-gis.app/privacy CHANGELOG: https://mapboard-gis.app/docs/ios/releases

Verdict
The clearest difference is review sentiment: Mapboard GIS at 100% against Outcrop's 0%. Mapboard GIS also leads on rating (4.5 vs 1.7). Outcrop's advantage is in-app purchases (none vs 1) and device support (3 vs 1). On price, ratings volume, update cadence and ads there is nothing between them.
