I would like to give this app more stars but it has too many glitches and a very clunky interface for the price — for any price. There is no visible text on any menu choice unless you press and hold there screen where the text should be. You have to guess what’s available under Help, Settings, and Chapter selections. There is no ability to shuffle cards within chapters or between chapters. I do appreciate the audio capability and have had no trouble with it, and the text on the cards is clear. This app has not been updated for 11 months, and with the current condition it is in, it really needs an update.
