Why do we say multitasking when using multiple apps to get one task done?

Recently I decided that I need to focus on one task at a time and not multitask. I set all my apps on my MacBook Air into full screen mode to “lock” myself in. I realised quickly that most tasks that I complete require multiple apps, for instance composing an email may require checking another email message or dragging in an image or file. I was spending more time swiping, loosing apps and dealing with how macOS behaves when using full screen apps.

I am now back to using apps as windows, like they should be (with 2 caveats). My focus has improved by removing other distractions, which I will post about soon.

For a closing thought, next time someone says an iPad is not good for multitasking do they mean “multiapping”?
