A one-click menu bar toggle that holds your computer awake — and checks that the system is really doing it. No more leaving caffeinate -dims running in a shell window.
Holds the same four system wake assertions as the caffeinate tool: display on, no idle system sleep, disk kept spinning, and no full sleep on AC power.
Click the mascot in your menu bar, or press ⌘K. It's full color when awake and dims when sleep is allowed.
Checks the real power management state every five seconds, so "Assertions: held" reflects what the OS is actually doing — not just what you clicked.
15 minutes to 8 hours, or a custom length, with a live countdown.
Allow sleep on battery, or release automatically below a low-battery cutoff you choose.
Stay awake automatically while chosen apps are running — a render, a build, or a presentation.
Optional ⌃⌥⌘K shortcut to toggle from anywhere. You can also let the screen saver and display sleep while the computer stays awake.
Start awake, so your computer is ready after every reboot. No app icon to manage, no clutter — it lives entirely in your menu bar.
No network access, no accounts, no analytics. Sandboxed and private.
A one-time purchase with no subscription and no ads.
