GPS Status & Toolbox – a useful app for calibrating GPS, accelerometer, and compass. After running the program, you will see a full-fledged compass that indicates the direction where you are looking. The device’s vertical and horizontal tilt options are also displayed. Available satellites, distance, the signal received from them, and many other equally useful parameters. The most interesting thing is the ability to calibrate the compass and accelerometer sensors, which will avoid ridiculous situations in the case of being in nature. A compass is a useful thing, but if it doesn’t work, there will be trouble. If you want, you can change the theme by choosing day, night, or normal, depending on your preferences.
