We have massively improved "My
Vocabulary" so you can now see the strength of each word and
practice weak ones.
See that little health bar on each word?
It represents the “strength” level of the word, figured out by our
algorithm. Every time you review a word using our Vocabulary
Trainer, its strength level will increase.
Simply tap the button at the bottom of
the screen and choose which set of words you’d like to train. If
you enjoy busuu, please leave a nice review on the store.
