Is there any chess app on iPad

That can handle comments and sub variations and show the game score next to the board ?

I plan to add this in Stockfish, but I first want to design a better format than PGN for storing games first (but of course, with support for PGN import). PGN has some annoying limitations, like the lack of support for formatted text in comments, diagrams, hyperlinks to other games, and null moves in variations.

Unfortunately, it's difficult to give any time frame for this, since my schedule is busy and unpredictable, and I have nowhere near as much time as I would like for hobby programming these days.
