Probably good of you already know them all. Probably good if you already know then all, otherwise obtuse and unhelpful. Spews adverts all over the place and doesn't let you try again once you've failed. Uninstalled.
Great app for memorizing joseki Well thought out spaced repetition app to memorize selected joseki. App shows a starting position and lets you play the next x number of moves. After seeing if you got the sequence right or not, you can examine both the sequence leading up to the original position as well as the sequence of the correct solution. You can also try out other variations for comparison.
Virus... Keeps telling my new phone has a virus. Maybe this program has a virus. Cannot get to see the sequence of moves (opened but not working)
Horrible Don't know what to do. Can't believe anyone gives more than 1 star for this horrible app.
Useless The app makes no sense and is basically useless.
Thanks for this app.
