Very effective app!

I absolutely love Knowji! It provides examples sentences with the vocabulary and collocations so that you understand how the word is used. There are pictures that accompany these sentences so this helps when learning the vocabulary as well. Another thing I really like are the reminders that tell you when its time to review the words (again). I think this is what has truly helped me learn the vocabulary.
