With apologies to the nice people at Oxford, dictionaries don’t usually look all that great. But LookUp is a dictionary for those with a penchant for aesthetics; the app delivers its daily definitions with illustrations that trigger both sides of your brain. Learn from a mahoosive collection of words like reticent, impresario, and mahoosive, which, we just learned, is really a word. Tap a card for pronunciations, origins, and synonyms; heart a word if you have a particular adulation for it.
