System Scope is a focused dashboard for checking your iPhone's current system status and recent changes. ■ WHAT YOU CAN MONITOR • CPU usage with a live history graph • Memory usage • Used and available storage • Battery level and charging state • Device thermal state, uptime and OS information ■ PRO • Measure a game session using start and end readings: average CPU, memory change, battery drain and thermal state • Extend history from 60 seconds to 15 minutes • Save before-and-after snapshots and compare changes • Export diagnostic snapshots as CSV System Scope has no ads or login. Exact CPU, memory, battery and thermal readings remain on your device and are never transmitted. Anonymous interaction events are sent to Google Analytics for Firebase only if you opt in at first launch, and can be disabled anytime in the app. We intentionally do not offer “memory cleaning” or “speed boosting” features whose effect cannot be guaranteed on iOS. Due to iOS sandbox restrictions, System Scope cannot display per-app CPU or memory usage, list running processes, collect an in-game timeline, or close other apps. Game Measurement calculates device-wide session averages from start and end readings.

Verdict
The clearest difference is update cadence: System Scope at every 6 weeks against 差圧チェッカー's every 3 months. 差圧チェッカー's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
