Ease of use refers to the property of a product or thing that a user can operate without having to overcome a steep learning curve. Things with high ease of use will be intuitive to the average user in the target market for the product. The term is often used as a goal during the design of a product, as well as being used for marketing purposes. Put simply, things with "high ease of use" are easy to use.

However, some experts distinguish ease of use from ease of learning, especially when the design of a product involves a tradeoff between the two goals.
