Ghost Board is a free spirit board application developed by Spirit Group Detector for Android devices. This application falls under the Lifestyle category and offers a fun way to interact with spirits using a semantic engine.

Ghost Board has two main features, the first one being the spirit box. You can ask yes or no questions and the engine will provide answers beyond just yes or no. The second feature is the ghost detector, which can be activated by asking questions such as "is there someone?" or "who are you?".

The application also has a spirit table that allows you to choose who you want to interact with and say goodbye when you're done. However, it's important to note that this application is solely for entertainment purposes and the results should not be taken too seriously.

Overall, Ghost Board is a fun and easy-to-use application for anyone interested in the paranormal.
