When you really want to drill down in remembering and understanding the structure of a sentence, you can also have LingoZING! read the text to you slowly, word by word. Again, the voices are not generated by a program but by native speakers who recorded them pronouncing each word separately and slowly. You can also make LingoZING! display and slowly read all the bubbles in a book sequentially, without having to tap each scene and bubble (tap a page or scene with three fingers).
