Best Free Compass Apps for iPhone/iPad/iOS (What is the best free compass app?)
If you are looking for a free compass app for Android for camping, off-roading, or any other activity where you need to let others know where you are, this is the app for you.
This Android app is part of the Smart Tools app collection, which also offers useful apps such as a metal detector, a spirit level, and a distance measuring app.
If you install this compass app, you won’t have to worry about the permission request. It does require access to your location coordinates to calculate correctly; you’ll want to have those handy, especially if you’re out on a large body of water with your boat.
