1. Wordly

Wordly adheres to the traditional adage of “one new word every day.” It is the simplest app on the list.

As a result, you’ll have no trouble understanding how the term is utilized in a phrase.

You can only change one setting, which is to display the word of the day at a day’s notice. It is also possible to share it with others.
