This software shows the user a verb in its infinitive (no translation, no audio) and, after a pause whose length the user chooses, it shows a conjugation of the verb. The user chooses, "Yes" or "No," and the software moves on to the next verb. I believe the software is showing the CORRECT conjugation and asking whether the user guessed it correctly before it appeared. But for all I know, the yes or no could be answers to whether in fact that conjugation is correct. There is a respectable dictionary of conjugations here, but there is no reference for the meaning or context of the forms themselves. So if you already know what "PQP" means, the difference between, "Passe Comp." and "Passe Simp.," and when to use them, this glossary will be worth the $2 by itself. If not, you may need a textbook to go with your iPhone ap.
