<h3>The reason why</h3>
<p>Phones assume that you are walking along streets, or running along tracks or cycling. They are <b>very, very bad</b> at making the right guesses on the Totes Gebirge plateau.

<h1>Compass & Clino on your phone</h1>

<h2>The Compass app on your phone</h2>
<p>First of all, ensure that you have one. <a href="https://www.androidauthority.com/best-compass-apps-android-2-954789/">Compass & Altimeter</a> is a good one, completely free (but turn off the altimeter setting as it does not do what you think it does).
<p>Turn OFF "precise location" - all that does it connect to wi-fi and cell-phone masts so that it can send you targeted ads and guess your altitude based on the altitude of the wi-fi point. Entirely unuseful - and frankly misleading - on the plateau.
<p>Turn OFF altitude - useless and misleading on the plateau.

<img src='/handbook/computing/t/Screenshot_20260203-140430.jpg' alt="screenshot compass app settings" /></a>
<p class="caption">Settings</p></div>
<p>Change the setting to MAGNETIC NORTH not True North. All our survey instruments use magnetic north, and this needs to be compatible with surveys. You may be using this compass app to determine the location of a cave entrance with respect to the nearest GPS point. You do NOT want "geographic" north.
<p>Do NOT select "gradians" for the angle units. All our Austrian surveys use 360 degree angles, not 400 gradians, for a full circle.
<h2>Clino</h2>
<p>A useful one is <a href="https://www.appbrain.com/app/laser-level/com.exatools.laserlevel"> Laser Level & Clinometer</a>. Some ads, and it does not work quite how we would like (unlike "Theodolite", which unfortunately costs money and only works on iPhones).
<div class="onleft"> <a href='/handbook/computing/i/dioptera_screen.jpg'><img src='/handbook/computing/t/dioptera_screen.jpg' /></a>&nbsp;</div>
<p>There used to be an app <a href="https://dioptra.en.aptoide.com/app">Dioptera</a> which does exactly what we want: point it at the cave entrance and it gives you compass and clino readings, but it is not on the Google app store or F-droid, you have to install the apk yourself and there is no safety guarantee. All other free apps of this type seem to be unusable with obstructive Temu ads.
