Nucleo: System Cleaner Monitor
Free Up Disk Space, Clean Junk
Only for Mac
Free · In‑App Purchases
Mac
Nucleo is a native Mac utility that frees up disk space, removes apps completely, and shows you exactly what your Mac is doing right now — all in one clean, fast app built for Apple silicon.
RECLAIM YOUR DISK SPACE
Scan caches, logs, temporary files, installer leftovers, and developer junk from Xcode, Homebrew, npm and Docker. Nucleo always shows a full preview before anything is removed, and everything goes to the Trash, so every action is reversible.
UNINSTALL APPS COMPLETELY
Dragging an app to the Trash leaves behind preferences, caches, and support files. Nucleo finds those leftovers and removes them with the app, recovering space you did not know you had lost.
SEE WHAT IS EATING YOUR STORAGE
Disk Map turns your drive into a visual breakdown, so the biggest folders are obvious at a glance. Drill down, spot the space hogs, and clear them with confidence.
FIND SIMILAR PHOTOS
Scan your library for near-identical shots and bursts, review them side by side, and keep only the best one.
CONTROL STARTUP ITEMS
Login items and background agents quietly slow down every boot. See the full list, understand what each one does, and switch off what you do not need.
LIVE HARDWARE MONITORING
Read real sensors, not estimates: CPU and GPU temperature, SSD and battery temperature, fan speed, CPU and memory load, and per-cluster activity on Apple silicon. Live charts show how your Mac behaves under load.
BATTERY HEALTH
Track capacity, cycle count, charge state, and temperature over time, so you know when your battery is genuinely wearing out.
MENU BAR MONITOR
Keep CPU load and the hottest sensor visible in your menu bar. Click for the full panel, without interrupting your work.
SMART CARE
One check reviews storage, startup load, memory pressure, and thermals, then tells you in plain language what is worth fixing.
BUILT FOR YOUR MAC
Nucleo is written in native Swift and SwiftUI for macOS. It is light, quick to launch, and designed to respect your Mac rather than nag it. Everything is analyzed locally on your machine.
PRIVACY FIRST
Your files never leave your Mac. Nucleo does not upload, sell, or share your data, and there are no ads.
Available in English, Russian, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Turkish, Japanese, Korean, Simplified Chinese, and Traditional Chinese.
