Quiz App

Hi, I’m wanting to build a quiz app with a database of a few hundred questions (maybe more) There needs to be a log in/create account feature, leaderboards, private leaderboards and the ability to play with friends i.e. by an invite. I’d also be looking at features such as “clues/hints” like a 50/50 and “lives” per day feature. The option to reveal such items would incur a fee.

Please post any examples of similar or general app works.
