Overall now seems best Android interpreter with good points outweighing bad. Good: automatic download of story covers and blurb from IFDB  copes with all zcode versions  saves in quetzal format so can continue story on other interpreters e.g. Windows Frotz. Bad: stupid name  interface not as slick as others e.g. Text Fiction  night mode puts command prompt BELOW shortcut buttons which is really fiddly.
