iQuit is a micro-app does one thing and does it well.
IT QUITS ALL OPEN APPS WITH ONE CLICK.
Oh, sure, you could restart your Mac to quit all apps - but you don't always need to restart. And quitting apps one-at-a-time is like pulling teeth!
Just be aware that after you launch it, all apps will quit IMMEDIATELY. There's no welcome screen, etc. Double click, wait a few seconds and you're done.
