Free · In‑App Purchases
Mac
See CPU, memory and disk status in your Mac menu bar. Get clear signals and practical recommendations. Core monitoring is free; optional Pro purchase available.
Understand your Mac’s current load at a glance. RC Signal shows CPU, memory and startup-disk status with clear menu-bar indicators. Open the detailed view for current readings and Mac Health Diagnosis.
FREE CORE MONITORING
Check the basic status of your Mac and review practical recommendations without buying Pro.
OPTIONAL PRO: ONE-TIME PURCHASE
Unlock trends, battery and external-drive analysis, custom rules, presets, alerts and diagnostic report export. RC Signal Pro is a non-consumable in-app purchase, not a monthly subscription. There is no recurring charge or subscription trial. The App Store shows your local price before you confirm.
For Mac users who want to understand resource usage without keeping a technical monitor open all day. Recommendations do not replace checking an app’s work before stopping it. Battery features require a Mac laptop.
