StraboField
Formally StraboSpot2
Free · Designed for iPad. Not verified for macOS.
StraboField is a powerful, all-in-one mobile app designed to streamline your geological fieldwork. Record observations, capture photos and sketches, collect orientation data, create geologic maps and stratigraphic sections — all from a single, map-centered platform.
Easily collect spatially referenced data using point, line, or polygon-based Spots. Work across multiple scales using nested Spots and high-resolution image basemaps. Designed by geologists, for geologists, StraboField supports workflows across subdisciplines including structural geology, sedimentology, petrology, volcanology, and geomorphology.
** Key Features: **
* Capture field data with photos, sketches, and notes
* Collect georeferenced orientation and spatial data
* Use custom or built-in basemaps offline
* Create multi-scale observations with nested Spots
* Organize and back up data locally or to StraboSpot.org
* StraboField is fully functional offline, making it ideal for remote fieldwork. Once online, your data can be synced to the StraboSpot digital data system at StraboSpot.org — an open- source platform supported by the National Science Foundation.
more This app has made my data collection in the field easier and certainly more organized!My photos, notes, gps points, and measurements are all in one place at the end of the day! There is a lot of functionality I still need to try out but it’s been great so far and I have enjoyed showing my students that they can collect geologic data on their phones without the need of specialized compasses or equipment!

Functionality tanked all around and so many bugs I don’t have time to detail them. I miss the original version, this version is almost unusable in the same ways.

Tappable Empty State Text - Empty list placeholders in the Notebook (e.g., "No Measurements") are now tappable and navigate directly to where you can add data.
Bug Fixes
Fixed a long-standing issue where photos taken in portrait orientation on iOS were saved rotated 90°.
Increased the network timeout from 60 seconds to 5 minutes to prevent false timeout errors when uploading large projects.
