La Ban So is an Android application that serves as an all-in-one compass and Feng Shui tool. Developed by VSCOM, this free utility tool provides users with a broad range of features and functions.

One of the app's primary features is its compass, which displays the direction East, South, West, and North, with degrees on top. Users can change the compass's color and rotate the arrow to point in the direction they want to know. However, the compass's accuracy is dependent on the accuracy of the phone sensor.

Apart from the compass, La Ban So also has a GPS information display that shows latitude, longitude, and address. The app also offers Feng Shui information, which includes lucky and unlucky directions based on your age. And, if your device does not support a sensor, you can still check Feng Shui with the direction you know in advance. The program also includes a calendar and lunar calendar, as well as 12 Earthly branches time.

Overall, La Ban So is an excellent tool for those who want to determine the direction or location they want to know and learn more about Feng Shui. However, it is important to note that the app's accuracy is dependent on the phone sensor's precision.
