I suppose StultitiaSimplex works on phone calls? The app seems good so far. but the wav playback stops about 0.5 sec before it should, what's with it? Also I have some ideas. Please add an option for creating pages with user defined titles. Like greetings, introduction, replies, questions etc. If one page doesn't have enough room for buttons, make the page scrollable. Make the other buttons accessible while the sound is playing i.e. dim the one button instead of a dialog box. Different button groups for different voices selectable from the top menu. Maybe mp3 support. The app could be used against telemarketers.
