Simple Family & Friends Games App

I'm looking for an experienced app developer to create a simple games app for both iOS and Android. The app will have various question sets tailored for different groups, such as family, girls' night, and couples. Key Features: - Monthly membership system that grants users access to all question sets. - A 'play' button that retrieves a randomized question from the chosen game. I have my own graphics for the app, so no graphic design services will be required. The ideal candidate for this project should have: - Proven experience in cross-platform app development. - A strong understanding of implementing subscription-based systems in apps. - Ability to deliver a simple, user-friendly interface. Please note: Access to all question sets is included in the monthly membership, but the system does not need to accommodate an ad-free experience or exclusive question sets at this stage.
