Poll players in ios game?

Question

iOS

Friends, do you have any ideas for organizing polls in ios games. We want to distribute the beta version of the game to a certain circle of people (scattered around the world) and ask them what they like and what they don't like. Some tool is needed for this. Questions should appear after a certain completed level in the game. The questionnaire should be able to work offline and then send data to the server (when a connection is available). Further analysis. The game is written in Unity. Tell me, do you know any solution to this problem?
