Which is the right business model?

This weekend I'm going to build my MVP in Bubble.io.

The idea is about to help padel player (a very famous sport in center Italy) to find its teammate. The prototype will be a matching app like Tinder.

Now my question. Which type of model it's right for this kind of business? Subscription? Freemium? Ads in-app? Purchase in-app?

The app solve a very painful point for padel community but I think that the must for this project its to make it freely accessible to all to use.

But then?..

Thanks guys!
