Pro System Monitor: CPU & RAM

About

Pro System Monitor shows what your iPhone is doing right now and what hardware it has: live CPU, memory, battery, storage and network monitoring, full device information, hardware tests and a performance benchmark. Every value says where it comes from: read live from iOS, derived from those readings, published by Apple, or entered by you. SYSTEM MONITOR • CPU activity per core, with history and load averages • Memory in use and memory composition: active, wired, compressed and inactive • Storage capacity, available space as Settings counts it, and purgeable space • Battery level, charging state, Low Power Mode and thermal state • Network activity for Wi-Fi and cellular DEVICE INFORMATION • Model, chip, display, cameras, audio, sensors, system and connectivity • Apple's published specifications for your model, and side-by-side comparisons with other models • The sensors, cameras and radios iOS reports HARDWARE TESTS • 11 tests you run yourself: display patterns, HDR and SDR, touch coverage, camera and microphone, speaker channels, motion sensors, step measurement, proximity sensor, Face ID or Touch ID, haptic feedback and NFC tags • A guided device inspection for buying or selling a phone. You judge each result; the app does not certify hardware. PERFORMANCE BENCHMARK • Processor, GPU, memory and storage workloads in about 15 seconds • Benchmark points for comparing the same iPhone over time, not a ranking against other phones DEVICE CHECK AND REPORTS • Condition checks with stated thresholds for storage, thermal state, battery and memory, and no made-up score • Share a check card image, save snapshots, and export PDF, CSV and spreadsheet reports • Recordings, long-term trends and a battery health log you fill in from Settings ONE PURCHASE One in-app purchase unlocks the full app. No subscription, no ads and no account. The purchase belongs to your Apple Account and restores on your other devices. WHAT THIS APP DOES NOT DO It does not clean memory, speed up your device, read battery health or temperature, or see other apps. Readings stay on your device unless you share them.
