Geoid App Reviews

This app is cool if it would work properly. Manual input for strikes are backwards and you can't even enter them in strike and dip notation. If these problems would be fixed five stars for sure. Until then a waste of five dollars.

Fast, Accurate, and Easy to Use

This app is fantastic! I love the options to plot and analyze your data on stereo nets and rose diagrams, the ability to export a text or csv file, and the option to take a photo along with a measurement. This app is really well designed and easy to use.

I think it's worth the money. Have yet to really test in field (want to do a Brunton vs smartphone test) but it worked well on some homemade structures I made. Many great options and very easy to use. Recommended for structural geologists! What I liked: -Lets you use your iPhone as a compass to measure strike/dip, trend/plunge by using magnetometer. -Can enter data manually or using the magnetometer. -Plots circles (planes), and points (lines) on a stereonet (10 or 2 degree option) -Can compare stereonet to current plane. -Can highlight intersections of planes on steronet. -Many options to single out data on stereonet all quickly accessible. -Failure Analysis -Ability to export projects via bluetooth, email as text -Ability to store multiple projects -Very professional look (Looks like a tool and not a toy, if that matters to you) What I didn't like: -Won't export photo of stereonet (but you can always use the phone's 'Print Screen' function by simultaneously holding down "Hold" and the "Home" button. It says you can in the description, but I can't seem to find the option to send anything but a text file in either text or scv (comma separated values). -Kind of expensive. Give us geologists a break. We need to be saving our money for beer!

Overall i like this app. Although, It would be nice to be able to import data from a csv or txt

MDBarton's review is right on. The lack of English support is a major issue for me. As a graduate student in Geology, the data I collect is in various formats: quad (N30W, 20NE), azimuth (330, 20) and direction/dip (060,20). While the app appears to display data in different formats, the input seems to be only direction/dip. I really need to be able to enter data from different workers in whatever format they provide, especially in the field. As an iPhone/iPad developer (my real job!), I realize that the internal magnetometer and accelerometer is very precise, but not terribly accurate unless calibrated frequently. As such, I don't really trust the readings from someone else's iPhone/iPad unless I know how/when they calibrated it and whether the values are corrected for declination or not. With some apps, it's impossible to tell. I continue to prefer taking readings with my Brunton, then entering the data manually. Hence, the need for easy manual input in various formats. Otherwise, this is a very useful application for quick analysis in the field.
