We are almost finishing our app - it’s a quiz app for kids. Users (adults), can sign in and create questions to contribute to the pool. We will have about 10,000 questions to start with but users are welcomed to contribute. We have several categories such as astronomy, history, maths etc etc.
I wanted this app to be beneficial and useful for the kids but I also want to monetize it in a good way. I am thinking a freemium model, where users have to pay a monthly subscription like $2.99 per month to have unlimited content/quizzes. For free account, they can play 10 questions before they see an ad and then continue again 10 questions and repeat.
Users will collect one point for every question with the correct answer chosen. For 1000 points, they will be rewarded with some vouchers like Amazon voucher for them to use on Amazon site.
Anyone has direct experience in marketing an app like this. I would be grateful to exchange discussion etc.
