Needs more work The examples for each word are readable but the explanatory text is blacked out. When I scroll to the adjoining word the black background turns white and I can read the partial page. HTC ONE. Otherwise it performs as advertised, although I really don't like taking quizzes. The most important part is bugged.
Great app, but ... This and its sister apps are very good. Infuriatingly, the drag and drop quiz questions don't work on my phone.
Love it.... I am enjoying using this app and the other two in this series.
* Better support for tablets
* Minor bug fixes
