How I can filter unread cards on Iphone?

I expect Trello does not shows checked cards again and only show new comments or cards.

@alireza eskandarzadeh what do you mean by "unread cards"?

[alireza eskandarzadeh]

I mean those cards that I have not seen their comments yet.

@alireza eskandarzadeh Any cards you're watching will cause a notification for any comments, whether they mention you or not. On the mobile app, in the notifications section, you can choose All, Me or Comments.

The Comments section will show all comments on cards you're watching, Me will show only comments that mention you or cards/boards you have been added to or removed from.
