“App” is a noun.

“App” is a fairly common word in modern English.

An app is a type of software program, but the word usually refers to compact applications built for phones and tablets, often doing one focused job. "Program" is far broader, covering everything from operating systems to large desktop software. Every app is a program, but not every program is called an app.

Apps generally fall into three groups. Native apps are built for one platform, such as iOS or Android, and installed from an app store. Web apps run inside a browser with no installation. Hybrid apps combine both, wrapping web technology inside a downloadable shell. Each type balances performance, cost, and reach differently.

A website is viewed through a browser and loads each page over a live connection. An app is usually installed on your device, can work partly offline, and taps directly into hardware like the camera or GPS. Apps tend to feel faster and more integrated, while websites are instantly accessible anywhere without downloading.

"App" is simply a shortened form of "application," meaning application software. The clipping spread with the rise of smartphones and app stores around 2008. Although the full word still exists, "app" is now the everyday term, especially for the small, single-purpose programs people download onto their phones and tablets.
