Exactly what I wanted
The ranked mode automatically adjusts the computer difficulty to your level (up to 5dan) as your rank is updated with each game and can be played on 9*9, 13*13 and 19*19 boards.
United StatesSo far so good
I have enjoyed the layout and analytics when playing against the AI. sometimes I see not the best moves played by the AI, but perhaps this is appropriate for the difficulty level I have chosen. Great!
United StatesSuperb stand-alone iOS Baduk app
I’ve owned & played CrazyStone for almost 2 years now. Runs seamlessly on iOS, I’m 7-8 kyu and can beat this app at only 6-7 kyu, no lower, so it’s pretty accurately rated. You set the computers strength by Dan-kyu, so great flexibility. It’s much stronger than me if I “open the throttle” on its engine & if you search YTube, can see older vids of BattsGo Dwyrin, Hajin Lee, Hanayeol, and other high Dan players engaging w CrazyStone. Although one can play bots, like OGS, those require internet or cell connection; CS is a standalone app that can be played anywhere without data connection. Simple setting, saves all your games in sgf, can play human v human if you want to play friend & have no real board or are traveling (train, etc). With SmartGo Kifu moving to new subscription format, CS may be the best one-time paid iOS Go app. I love it. No relationship to game creator, just happy customer.
United StatesVery solid app.
High price tag, but I splurged anyway. It’s six dollars a year for the premium subscription inside the non Pro version for comparison. It doesn’t actually say this anywhere, but FYI there are no ads like in the non Pro version. A major reason I bought it. I am SDK trying to improve with many small-board games played quickly. The AI is strong (and pleasantly quick) when it tries (high Dan setting), but will allow the occasional odd mistake at weaker settings (play a bad ladder, overlook a big capture). The rating system is very nice. No real bugs that I can find. GUI is a bit kitsch but not distracting. Haven’t tried SGF file management yet.
United StatesTop Notch
This is probably the best Go/Baduk app for IOS. Well worth the money for a solid, professional quality game with so many features. I spoke with UNBALANCE and they do indeed intend to keep up with bug fixes and IOS changes. I recommend this over the other subscription based version, but that’s a personal choice. The engine is more than strong enough for me. I especially enjoy the rating and analysis modes. Also, this version supports landscape.
United StatesGreat for training
There are stronger apps out there now, but none that track your progress and automatically set up your games against a large selection of difficulty levels like this app. This app and SmartGo basically define my standards for what features I’m looking for in other go apps. Also “A Master of Go” is the strongest native go engine for iPhone... it’s just an iPhone implementation of the Leela Zero engine. I’m not strong enough to benefit from it though, and it’s lacking in features, so I still train on this app
