Self Enquiry is an app for spiritual seekers, it offers help by answering your questions. The Self here is the consciousness, or the Atman, or the higher self or the essence of all of us, the ultimate reality.
When you are seeking knowledge and ask a question to the Self, it reminds you that which you already know. This is introspection. Self Enquiry is like an assisted introspection.
It also has a built in quiz which calculates your spiritual score called spiritual quotient. This score is only an indicator of your present progress. Note that in order to ask any questions, you will need to take this short quiz.
