Fortune Teller: Yes or No App is an Android application developed by QLIntelligence. It is a lifestyle category app that allows users to ask yes or no questions and get random answers. The app works by letting users place their finger on the fingerprint and asking their question. The answers are random and do not predict the future, so users should not make any serious decisions based on the app's responses.

The app features an oracle-like and fortune-telling game, which functions similarly to a crystal ball fortune teller. It is an offline game that provides fun and entertainment to users who are looking for a quick answer to their questions. The app does not require an internet connection to function, making it accessible anytime and anywhere.
