From the developer:
Critical Updates keeps you informed of when a background update of the listed components occurs. Critical Updates refreshes the Components table on launch, and about once every 60 minutes if left running; it polls the App Store for security updates on launch and about once every 10 seconds while running. Critical Updates has a very low energy and resource footprint and can be left running with virtually no impact on system resources.
