About

This app assists geologists in collecting, visualizing, and analyzing geological orientation data. It offers automatic data entry using device sensors and augmented reality, manual input options, and various plotting and calculation tools for geological features.

Automatic data entry via device orientation
Augmented reality for strike and dip measurement
Manual data entry via stereonet or text fields
Plotting of lines and planes with user-defined types
Basic geological calculations (rotations, angles, slope stability)
Plotting of mean vectors, rose diagrams, and contour lines
View plots from any orientation

What's New in Stereonet Mobile

4.5.2

July 1, 2026

v. 4.5.2 -- 1 July 2026 • FIXED: This version fixes an issue uploading to and downloading from StraboSpot. v. 4.5.0 -- 20 April 2026 (It's been a while!) • NEW -- Stereonet Mobile now can account for camera bumps/plateaus and other non-planar elements on the back side of your phone when measuring a strike and dip by placing the back of the phone flush against the plane to be measured. There is a new calibration feature, accessible from the Settings Screen (gear icon) , "Correction for Camera Bump" that enables the app to figure out exactly what the correction factor should be for your phone and case. The calibration take maybe a minute and, once set will be applied to all new measurements, even after switching projects. • NEW -- The Edit Type screen now uses the standard iOS color picker to select colors rather than the RGBA sliders in previous versions. • IMPROVED --- The app now uses the new Apple design language throughout if you are on iOS or iPad OS 26. Rose diagrams now include all data sets. There have also been numerous interface tweaks and fine tuning. The users manual, accessible from the Settings Screen, has been updated. • FIXED -- some minor bugs that would cause a line on plane (i.e., rake) not to function properly under certain circumstances.

A bit frustrating

I wish you could have multiple projects or locations.

The UI design results in the auto function frequently turning off or the location turning off resulting in having to retake a bunch of measurements.

Response from developer

Hi Joe. Thanks for the update of your review. I think you’re referring to the “tap anywhere on the plot to turn off the auto feature” behavior. As you know, geologists are frequently taking measurements on awkward surfaces — e.g., overhanging bedding planes, while hanging off unstable ledges, etc. — so the idea was to provide a large tap target that the user could hit without actually being able to see the face of their phone at all. But, your review highlights the downside of this approach. I could put in an option allowing the user to disable the behavior or make it a double tap but the latter has the disadvantage that it could shake the phone enough to disturb the measurement in some situations. If you have any suggestions, please feel free to contact me via my web page.

Rough

This thing is so rough to use, absolutely 0 quality of life features.

Response from developer

Hi Joe. I’m always interested in making my apps better but your review gives me no information to go on. What “quality of life” features do you expect in a scientific plotting and measuring app? How would you suggest the app work to make measurements faster, easier, and more accurate?

Great start, having a little trouble with importing data

I love using this desktop program and I’m really happy to see the addition of an iOS app.

I’ve never been able to import data sets between my pc and the mobile app without it crashing or saying the mobile stereonet format is unreadable. Because of that I can’t really use the app the way I’d like. I’m unsure if it’s a data file issue, but it happens on iPad, iPhone and multiple devices. I’ve redownloaded the app on all of these and it still crashes whenever attempting to import files.

Unsure if this is a bug but it’s really inhibiting and for me has made the mobile app unusable really. I’ve just reverted to writing the data manually and doing my nets on the pc when I get back to the office.

Thank you to the development crew though, I appreciate the tool and the attempts to make it as functional as possible. I’ll keep trying and I hope there’s a simple fix for this issue because I’d love to leave the laptop at home and have my data in my pocket on field trips.

Great consolidation

Really good package of functions, however, big issue with the settings button. You can access settings but when clicking back it closes the app, regardless of any changes within the settings. Looking forward to this fix!

FAQ

What is Stereonet Mobile used for?

Stereonet Mobile is designed to help geologists collect, visualize, and analyze geological orientation data. It allows for automatic and manual data entry, plotting of geological features, and basic calculations.

Can Stereonet Mobile use augmented reality?

Yes, Stereonet Mobile is the only geology compass app that can use augmented reality to record the strike and dip of planes using the sighting method and the device camera.

What kind of geological data can Stereonet Mobile plot?

Stereonet Mobile can plot lines and planes, which can be tagged using user-defined data types such as bedding, cleavage, or slickensides.

Does Stereonet Mobile perform calculations?

Yes, Stereonet Mobile can perform basic calculations including rotations about any axis, planes from poles or poles from planes, measure angles between lines and planes, and basic slope stability calculations.

What devices does Stereonet Mobile work on?

Stereonet Mobile works on iPhones, iPads, and iPods. Devices lacking a cellular data connection can still use the app but have fewer sensors and cannot be used in automatic data collection mode.

Is Stereonet Mobile free to use?
