Compass is called as -
1. Brújula in Spanish (Español)
2. Boussole in French (Boussole)

Use this app just like a real compass and for best results keep your device on a flat surface. This is a very simple to use app and uses very less battery.

This app reads earth magnetic field using the 'Magnetic Sensor' inside your phone.
Hence this app will not work - in case if your device doesn't have 'Magnetic Sensor'.

Also, please note that objects such as - iron/steel peripherals or utensils, big speakers may influence the 'Magnetic Sensor' and cause app to point in wrong direction. In such case, please move away to avoid deviation.
