Pro System Monitor: CPU & RAM

Pro System Monitor shows what your iPhone is doing right now: per-core CPU, memory composition, storage with purgeable space, battery and thermal state, and Wi-Fi and cellular traffic, with every value labelled by its source. It also includes Apple's published specs and model comparisons, 11 user-run hardware tests, a guided used-phone inspection and a roughly 15-second benchmark for tracking the same iPhone over time, plus PDF and CSV reports. One in-app purchase unlocks the full app: no subscription, no ads and no account. It does not clean memory, speed up the device, or read battery health or temperature.
