Do you find a word or sentence is too easy, irrelevant or you just don't want to learn it? On the app, you can mark an item as 'I already know this' to ensure it won't come up for review.
Ignoring words in the Android app
While doing a Learn or Review session in the app, click the I already know this button at the bottom of any presentation screen.
Alternatively, go to the Learn tab, click on any Scenario and select 'Mark as known' via the ellipsis next to any word or phrase.
