Free · In‑App Purchases

Mac

New: 0.2-second updates, improved core labels, and menus that fit your screen. Choose LEDs, VU meters, or a CPU bar. Try free for seven days; unlock once. See what your Mac's CPU is doing at a glance. CPULEDs brings live CPU activity to your menu bar with per-core lights, segmented VU meters, or a compact CPU bar. Follow the load during builds, games, audio sessions, and exports without keeping a large monitoring window open. THREE WAYS TO WATCH • Per-core LEDs with five shapes and three finishes. • Segmented VU meters with adjustable height and width. • A single CPU bar showing overall usage. SEE THE DETAILS Click the menu bar indicator for overall CPU usage and a per-core breakdown. Performance and efficiency labels are available on supported Apple Silicon hardware; other configurations use generic core labels. FITS YOUR SCREEN The menu opens to show the full breakdown when space allows. On smaller displays, extra rows scroll while Settings and Quit stay within reach. Settings expands to fit its contents within the available screen area. A wide per-core menu bar display automatically switches to a compact indicator. If the menu bar gets crowded, reopen CPULEDs from Finder to reach Settings. MAKE IT YOURS Choose your display style, size, spacing, brightness, color thresholds, and optional core letters. See changes in the live Appearance preview. Enable launch at login to keep CPU activity close at hand. SET YOUR UPDATE INTERVAL Choose 0.2, 0.3, 0.5, 1, 2, or 3 seconds between CPU readings. The default is 1 second. Faster updates can increase CPU usage and battery consumption. LOCAL CPU MONITORING CPU readings stay on your Mac. No analytics or tracking. Apple's App Store handles product prices, purchases, and restores. SEVEN DAYS TO TRY IT The free seven-day trial includes live monitoring and every display style. A single lifetime unlock keeps them available afterward. No subscription. See the localized one-time price in the app before purchasing. Already purchased? Use Restore Purchases in Settings → About. Requires macOS 15.6 or later.
