Multiplayer Trivia App for iOS

iOS Multiplayer Trivia Game App (Based on an Existing Game)
.
Hello,

I'm looking for a developer (or a team) to build a trivia-based game app for iOS. The concept of the game already exists online, and I would like to create a similar version with some modifications and additional new features.

Game Concept:
A question and answer game.

Players compete 1 vs 1 or team vs team.

App Requirements:
Platform: iOS only.

Text chat support between players.

Multiplayer system with room creation and joining.

Ability for players to play together in real-time or asynchronously (to be discussed).

I will share the reference game privately so you can understand exactly what needs to be cloned and modified.

What I Need from You:
A detailed offer including:

Estimated timeline.

Estimated cost.

The tech stack or tools you plan to use.

Any suggestions or feedback you have to improve the project.

Please feel free to message me privately to get the full details of the original game and discuss further.

Thank you,
Looking forward to your offers.
