Part of my master's degree, I developed a quiz app which will offer you a multiple choice questions and 30 seconds to answer each of them.
A quiz app that uses Retrofit to fetch the questions from the OpenDB API http://opentdb.com/ based on user selection of category, difficulty and number of questions. The app authenticate the users using Firebase Auth and saves thier data. We use fireStore DB to store user unlocked categories and RealTime DB for coin counts. The user can modify his/her information including adding a profile picture which is then stored in the firebase storage. The app has a LeaderBoard Fragment that displays a static data with random generated scores. Also, the app uses Butterknife to bind all the views.
