Drafts has several small but handy features. The app keeps track of both your word and character count, which is extremely useful when you are composing a character-limited tweet or a text message. There’s also a search function that’ll help you find the important note you created last month. If you own the companion app Terminology, you can highlight a word in Drafts and easily look up its definition and usage.
