About this app

Rocklogger is a geological tool for measuring the orientation of rock outcrops. It uses the phone's compass and orientation sensors to measure dip & dip direction, or dip & strike, in a single click.
GPS and magnetic field information can also be saved, along with details on the rock plane & type.

Key features:
-Log dip & strike or dip & dip direction by placing the phone on the rock/plane in any orientation (using the rotating symbol and quick help features as guides).
-Android Wear companion app to view and save (paid only) live sensor readings from your phone remotely on your watch, and vice-versa. Alternatively, log remotely using a wired headset (paid only) as a remote control. Great for logging hard-to-reach surfaces
-Plot logs on a map, with correct dip/strike symbols
-Plot logs on alternate basemaps from various sources including MapBox, zip files and the web (paid only)
-Plot poles or planes from logs on a stereonet, and interpret by touching the plot to find trends and intersections (paid only)
-Define your own extra text and dropdown fields, to fit your logging scheme (paid only)
-Log the ambient magnetic field
-Launch the camera to take photos while logging. Notes and GPS data are saved to the log file. Photos are stored with the log file, and are automatically attached when you send a log via email from the browser screen

The log is saved to a .csv file, which can be sent to Excel / Mapinfo / etc for interpreting. Paid versions can also export KML files for use in Google Earth (Android or desktop version).

Taking the strike and dip of outcrops with a compass / declinometer usually takes a few minutes per rock. With Rocklogger, many measurements of an outcrop can be taken in seconds (in any orientation). It also works upside-down, eg for logging overhang in a mine.

The evaluation version is limited to saving 3 records per 3 minutes, and has the stereonet plotter, KML export and custom basemap features disabled. Rocklogger Unlocker is available for purchase to disable the evaluation version restrictions.

Geologist here, with high hopes. Not ready for prime time. Constant random buzzing of my phone vibrate feature is annoying, and drains the battery. Font selection very difficult to read (black with white border); no actual instructions, and many vague program options; opened in strike and dip view, but I could never get back there, so could not use the program; photo option not working or unclear how to use. I will gladly pay for this if it becomes user-functional. Concept is brilliant.

Not an expert on dip and strike but this App seems to be the perfect answer for easily recording it on your mobile phone. Very easy to use and record the location, dip and strike, or dip and dip direction. Can transfer the KML file to Google Earth or whatever. I use Gavin Brock’s Google Earth 50k OS overlay for mapping in the UK.

An excellent app for geological mapping using mobile phones. You can use it to plot the structural symbols directly on Google earth and also to send the field data to your email.
