The app is designed with a user-friendly interface that is visually appealing and easy to use on Android smartphones and tablets running Android 2.3 and up. The app also supports the digital compass sensors of major brands such as Samsung, HTC, Sony, and LG.

It helps to determine the orientation of a house, room, or building, as well as the best placement of furniture, decorations, and other items. The app also includes additional features such as:

1. House orientation: helps to determine the best direction for building a house or choosing a new home based on feng shui principles.

2. Building age: helps to determine the best year for building or renovating a house based on the owner's birth year.
