Igowin HD is the IPAD version of Many faces of Go
This App is the most comprehensive Go playing programme available for IPads. It reproduces most of the features of Many Faces of Go (I have versions 11 and 12 on my PC), although the navigation of its different features is not as intuitive as MFOG. Igowin would be improved by a help menu showing all the features.
The touch screen of the Ipad works fine, but some might prefer to use a stylus to enter their moves, (especially those with clumsy, larger fingers...).
An annoying defect of the programme is that it does not adjust its angle to the screen's position i.e. it does not set itself horizontally when the tablet is held horizontally, as with most other Apps on the Ipad. As a result it can only be viewed vertically, which is a drawback if you are used to propping the tablet on a stand or its magnetic cover which rolls back into a stand.
