Problem
“Cleaning” apps for Mac promise to free up RAM with tricks that don't work, delete things without explaining, and sometimes touch what they shouldn't.
Nexus Performance · Native Mac app
Native Mac app that optimizes your computer's performance
A native Mac app that measures live how the computer is performing and suggests, with explanations, what to clean up or close so it runs better. Everything is processed on the computer itself.

The project in 30 seconds
What it solves and for whom
Solution
Nexus reads memory, processor, disk, battery, and temperature, and with one click proposes a plan split into Memory, Disk, and To review. Each item can be unchecked, and at the end it shows what was recovered, measured before and after.
Who it's for
People who work long hours on their Mac—development, design, AI—and find it slow or with a full disk.
What it does
Honest with your computer
Health dashboard
Performance score and live readings of RAM, CPU, temperature, disk, and battery.
One-click optimization
Analyzes apps, forgotten processes, caches, old downloads, and startup items, and proposes a plan you review before applying.
Protections by design
Does not touch development or AI processes in use or apps with activity; protected items appear with a lock and the reason.
Disk explorer
Disk map, verified duplicates, forgotten installers, and dependencies from idle projects, with an app uninstaller.
