CrazyStone DeepLearning Pro

It shouldn't be so hard to open an sgf file with this app. Do a Google search for iOS file association.

This is by far the best app for GO players available(I have most). The analysis mode is a fantastic tool for any Kyu level player. Probably lower Dan level too. If you want to improve, play auto rating games and then analyze them. You WILL get stronger fast. It's pricey, but well worth it for the serious player.

Analyzing an existing SGF requires using a computer to sync files from iTunes (in 2017!), rather than allowing you to paste an SGF from the clipboard, or loading one from Safari. The analyze feature requires using another SGF editor like SmartGo to even see what alternate moves CrazyStone proposes, because (even on an iPad) the board coordinates are truncated and there's no indicator of "CS Best" on the board. (I'd like to see the top 3 moves, incidentally). These tiny things alone cause so much

Pros: It's very nice to have the ability to do basic blunder checking analysis on games, and as a DDK player I enjoy playing against the engine. Cons: The inability to import SGF in any way other than syncing through iTunes is a big disappointment. We need to be able to paste SGF as well as exporting to Crazy Stone from other apps, as well as export (with analysis, please!) SGF to other applications and not just via email. This could be a great app. As it stands, it's a great engine with a tol

This app is wonderful for my level.
