Oxford Dictionary app is the benchmark

Oxford dictionary app is the benchmark of all resources! I can describe it as the bible or Gita in the world of words. As a lawyer, I rely on this app even in court proceedings.

“Word of the day” is a standout feature

I am currently working on a romance novel. I save words for later in the favourites section. The word of the day is a standout feature for me, and I check it every morning.
