GOSU Joseki for Android
Nice joseki viewer with lots of modern variations. If only there is a toggle to control whether to show move sequence in numbers.
Very good. Superb and may in fact be the best on the market
Nice and simple app
Easy to use and good to learn

Great viewer for joseki. Actually allows zooming unlike other apps on the market. You can also work in different corners to see how the joseki influence each other.
