Technology is constantly changing and evolving with every new innovation. It's worth bearing in mind that some of the gadgets that your grandfather carried as a child, although they still function well, will probably get left and forgotten in some kitchen drawer. Which is the same for our generation and the next.

As you may be aware, phones are the modern "SWISS ARMY KNIFE" in the sense that phones have multiple functions. Smartphone companies provide app stores that can easily replace a lot of certain tools, and the compass is no exception. Mobile devices feature built-in hardware (a magnetometer) that transforms them into functional compasses using dedicated applications. Whether navigating a hike or testing a new route, popular downloadable options offer highly accurate directional tracking, augmented reality navigation overlays, and elevation readouts.

Usage Tips & Calibration

To ensure the best accuracy, keep the device parallel to the ground and away from high magnetic fields, metallic objects, or machinery, as these cause interference. If it becomes inaccurate, recalibrate your phone’s internal sensors by waving it in a figure-eight motion. [1, 2, 3]
