Howdy!

I'm looking for a free or paid iphone app that supports FEN. I use Stockfish to go through pgns of tactics, but it takes a while to go fron one problem to the next.

In Stockfish the process to get from game/problem in the pgn to the next is:

Game->Load Game->1001mates.pgn->select the game->Load Game.

And you need to remember which one you were just on so you can select the next one. Annoying.  I'd love to find an app where I can just click a "skip" button to go to the next game/problem in the pgn.
