How do some reviews have titles? Am I able to add a title to mine?

After adding a book I just finished reading, I read through the other reviews to see what other people thought. Most of the other reviews have titles.

The bold text, like "Loved this story!", "Fun story!!", and "Adorably good".

There's no field for a title when I do my review. Is it a mobile only option?
