What is an app?

The word app is short for application, which just means software built for a person rather than for another program. A note app, a calendar and a bank app are all the same category of thing: tools with a screen and a purpose.

What matters here

  • Built around a job rather than a feature list
  • Either installed or opened in a browser
  • Stores your data somewhere you should know about
  • Updates over time, which changes what it can do
  • The good ones get out of the way quickly

Installed and web apps

An installed app runs on your device and can work with local files. A web app runs on a server and needs a connection, but it works on any machine without installation. Many modern products ship both from one codebase.

What an app owns

Every app decides where your data lives: on your device, on the vendor's servers, or both. That decision affects backups, portability and what happens if the company disappears, and it is rarely on the marketing page.

When an app is the wrong shape

If you need one document, a word processor is not the answer. If you need a calculation, a spreadsheet wins. Apps are worth installing when the same job repeats and the friction of doing it by hand adds up.
