Brújula is an app for knowing where you're going with a compass on your smartphone, as its name suggests. Thanks to this app, you can find any cardinal direction with total ease and accuracy.
You'll have to calibrate your smartphone to get the right orientation, although the app helps you do so in just a few seconds. After that, you can use this app and all its features without a problem.
Of all the features included with this compass, a few in particular stand out: checking for true north, latitude and longitude, the sensor's status, your altitude, your rate of ascension... the app shows all this information on the main screen, although you can opt to see more or less of it.
Without a doubt, Brújula is one of the best apps of its kind, designed to help you know where you're going. Not only does it have tons of options, but it also lets you connect to Google Maps.
