Comparison
Two identical smartphones on a table. Left phone: dark mode, large font, no notification badges. Right phone: light mode, tiny font, 47 notification badges. Same model, same year. Different settings. Clean overhead shot.

Two identical phones. Same model, same year.

Phone A: dark mode, notifications off, font size 18. Phone B: light mode, all notifications, default font. Same hardware. Same software version.

The difference? Saved choices. Someone opened Settings, changed three values, and closed the app. Those choices persist. They stay until someone changes them again.

Settings are saved choices that control how software behaves.
