## Lambert Description
This app turns your iPhone (or iPad) into a geological compass, a tool for each geologist. It can be used to measure the direction of dip and the angle of dip of geological strata. The app shows the current device orientation in a realtime stereographic projection. The data can be previewed in projection diagrams (Wulff and Schmidt Net) and transferred to your computer. You can add text to the measurements and plot the measurement localities on a map.

## Lambert Reviews in United States

### ***** "A must have for geologists"
Simple and efficient alternative to bringing a bruntun with you in the field.  This one doesn't cost 300$. Just get it.
-- SteveDA77, 2014-03-31

### ***** "Work well"
Fast and efficient, I like it a lot!
-- Géologue, 2013-12-27

### ***** "Great!"
If you do field work this app is splendid.  Does all the work of a bunting compass and makes your rosé diagrams and stereo nets.  This is the future.
-- Jack of hearts egam, 2013-02-11

### ***-- "please make it work on ios5"
please make it work on ios5 
it dosent work
-- Kmwstar, 2011-10-21

### ****- "iPad2"
This app would be REALLY cool on an iPad2

... ditto on the alternate S/D formats in the previous comment
-- Field camp instructor, 2011-04-15

### ****- "Like it, here's what I need to love it"
So basically, the fact that this app plots measurements on a stereonet made me decide on it out of the three other strike/dip apps

DEVELOPER: are you aware searching strike and dip or brunton in the app store does NOT bring this app in the search results? ...add some keywords or add to the title...

Requests: please have an option to use strike and dip rather than bearing in the recorded data (and as the prominent readout) as well as an option for azimuth vs quadrant. 

*** a map view with data strike and dips overlaid would rock! Not to mention you would be the first app to have these!

In the settings you should have a 'classic' mode that works more like a real brunton utilizing 2 steps... For the skeptical. While I'm at it you should include far better instructions on the actual logistics of taking measurements with your app, it left me doing tests just to see if I am taking measurements with it correctly. 

An easy way to share these would rock too...

****update****
Developer, please address some of my issues? Thanks
