Pro Helps users learn thousands of words in a short amount of time
Con Only a few languages available
Currently only offers English and French. The website says there are 6 other languages in the works.
Con Not enough variety
Words are learned through fill-in-the-blank style problems, but they do not change, so the user is not challenged enough to be able to remember and use the learned words in circumstances different from the fill-in-the-blank sentences.
