DiskHealth PRO

DiskHealth PRO keeps an eye on your Mac's storage so you don't have to. A lightweight menu bar utility that reads S.M.A.R.T. data from your internal disk and shows you everything that matters at a glance.

Unlike heavy diagnostic apps you open once a year, DiskHealth PRO lives in your menu bar and gives you instant answers to "is my disk healthy?" without interrupting your workflow.

HEALTH SCORE AT A GLANCE
A beautiful semicircular gauge shows your disk's overall health as a percentage. Green, amber, orange, or red — you know the status instantly. The score is calculated from S.M.A.R.T. attributes including wear level, available spare, reallocated sectors, and critical warnings.

MENU BAR — ALWAYS VISIBLE
See your disk's temperature or health score right in the menu bar, without opening anything. Choose from multiple display modes:
• Icon only
• Icon + Temperature
• Icon + Health Score
• Icon + Score + Temperature

DETAILED METRICS
Click the menu bar icon to see quick metrics, or expand "All metrics" for the full picture:

Health — S.M.A.R.T. status, available spare, wear level, reallocated sectors, pending sectors
Lifetime — power-on hours, data written, data read, power cycles, unsafe shutdowns
Monitoring — temperature, integrity errors, uncorrectable errors, critical warnings

HEALTH HISTORY & CHARTS
Track how your disk's health changes over time. Interactive charts show health score, temperature, and data written trends over days, weeks, or months. Spot degradation early, before it becomes a problem.
