This is a smart digital compass with 3 distinct modes:

1. Cardinal works like a regular compass. It communicates with your phone's internal sensors to show you if you are facing North, South, East, or West. It even offers details on the 16-winds.

2. Measure angles like a protractor. You can point the phone at one object, click a button to set it to zero, and then turn the phone to point at a second object. The app will tell you exactly how many degrees you turned (for example, a 45° angle).

3. Locate helps you find a specific place. You pick a destination from a list, and the app uses GPS to find where you are. It then calculates the distance (in kilometers) and shows an arrow on the screen. When you point the phone directly toward that place, the arrow changes color to tell you that you're facing the right way.
