Sound application -- 2

I need an iPhone app. I already have a design for it, I just need it to be built. The iPhone app is similar to this app: [login to view URL] Users will choose one of three sounds to make (worth 5,10 or 15 points) and then a friend or random person will guess. Want to be able to add more sound options without requiring an update. Built on firebase. Sound options added here and user log in details stored here too (email, password, username) Log in via Facebook or Apple Google admob Will need to be submitted to App Store Strict budget and timeframe
