In short, yes, anyone on the BeReal app who is friends with the account your comment is posted on can see your comment below the post. In this regard, the BeReal app is no different from Facebook or Instagram. Say one of your friends responds to the "be real" notification and posts a photo of themselves, then you comment below the post saying "looks great!" or anything for that matter. Anyone who is friends with that friend will see your comment, as it is public to everyone who is friends with the poster.

Note that there is no private messaging feature on the BeReal app, which also means that if you were to comment on another user's picture, anyone who is friends with them can see your comment. You may be wondering, "What if my BeReal account is set to 'Private'?" and the answer is, your comment will still be visible to all users who are friends with the account that posted the photo.
Yes, when you post a comment on a friend's post, it doesn't matter if you're not friends with them, what matters is that the friend who posted the photo is friends with them.
So it's safe to say that if they aren't friends with the account that posted, your comment won't be seen by them or anyone else who isn't their friend on the BeReal app. Someone who isn't friends with the account that posted the photo is the only way they won't see your comment.
