Sometimes writing can be frustrating, especially when you can’t find the right words. Using the same words over and over make a blog or article boring to read, which will cost you readership. Fortunately, all writers have a trusty tool to call upon when they’re stuck in a rut: the thesaurus.

While it might seem ideal to carry a thesaurus around with you at all times, it’s not always practical. This dilemma can be solved with the use of a thesaurus app, which grants you all the knowledge of a thesaurus in the palm of your hand.

For this list, we’ve picked out some of the best thesaurus apps found on both Android and Apple mobile devices.
