Bartender is an award-winning app for macOS that superpowers your menu bar, giving you total control over your menu bar items, what's displayed, and when, with menu bar items only showing when you need them.
Bartender has changed how I organize my MacBar and finally got rid of the clutter. Love the way Bartender dynamically shows menu items depending on their status. For example, now I only see the battery icon when I'm at 20%!
