Compass Issues with iPhone 6s / 6s Plus and iOS 9 to 9.1??
Users reported malfunction of the compass, similar to what currently was reported from other apps which use the digital compass and/or gyrometer sensors of the iPhone 6s / 6s Plus.
These problems are not yet confirmed by Apple and the source for them is not clear at the moment. I cannot test and verify this on the Xcode Simulator and I currently have no iPhone 6s / 6s Plus available.
I therefore depend on user experience and encourage you to send me detailed bug info if you run into problems using Lambert on the 6s / 6s Plus.
However, if you own an 6s / 6s Plus and Lambert is running ok, you can also just klick here and send me the "Lambert works fine" message. Thanks!
Lambert is an app that turns your iPhone or iPad into a geological compass.
You can use Lambert to measure the direction and the angle of dip of geological strata or for the measurement of the plunge and plunge direction of lineations. All measurements will be stored and can be reviewed in data tables. The data can also be previewed in projection diagrams and transferred to your computer.
Using Lambert on the iPhone has a number of advantages in comparision to a conventional geological compass. The measurements are more precice than measurements with a conventional geological compass. You will also work faster because you don't have to adjust the iPhone on the schistosity plane. You only have to place the device on the plane and adjust it roughly in the direction of the dip. The program calculates the precise direction of the dip.
Also, it does not matter wheather you perform measurements in display-up or display-down device position. Therefore, you easyly can measure also on the downward side of geological planes.
