That's great to hear! If you're free this Saturday, do you have any special plans or activities in mind? Maybe you would like to see a movie, go out for a walk, or meet up with friends?... more

Your sentence is quite clear! Here is a slightly more natural way to say it:
"I'm fine, thank you. I'm free this Saturday."
Tips:
1. You don’t need “on” before days of the week when speaking casually.
2. Starting with “I’m fine, thank you” is common for polite replies.
3. You could also say, “I’m available this Saturday” or “I’m free this Saturday afternoon” for more detail.
