What’s that for?

[Silverobama]

Tonight I went to an English club. I sat next to a college student. She noticed that I was looking at her browsing at her phone (She was browsing on the phone.) and she asked me if I was single. I said “Yes”. The she pointed to the app. Perhaps because her spoken English wasn’t good she just pointing at the app. I then said:

What’s the name of the app? What’s it for?

She then told me in Chinese that it is an app for dating men and women.

Is my question natural?
