Convenient procedures, products and services are those intended to increase ease in accessibility, save resources (such as time, effort and energy) and decrease frustration. A modern convenience is a labor-saving device, service or substance which make a task easier or more efficient than a traditional method. Convenience is a relative concept, and depends on context. For example, automobiles were once considered a convenience, yet today are regarded as a normal part of life.

Because differences in lifestyles around the world, the term is a relative term based upon the conveniences previously available to a person or group. For instance, an American definition of 'modern convenience' is likely different from that of an individual living in a developing country. Most of the time, the term 'modern convenience' is used to express personal lifestyle and home life.
