questionnaire

Everyone can answer the questions they're comfortable with and then you can check a match's answers to the questions that you've answered yourself. In order to see the answers to questions that you haven't taken, you have to answer the corresponding question (to prevent ppl from saying what a match wants to hear).

To prevent addictive behavior and to reward consistent app use, there could be a limit to the number of questions that can be answered per day (e.g. 10 questions). Maybe this wouldn't apply to answering questions a match had answered (while looking at a match).

Premium users could then see a match % based on the questions and interest tags
