CoreScope: System Monitor

See what your iPhone is doing — live CPU, memory, battery, network and storage. Plus an IP/VPN/speed toolkit and a used-phone hardware check. No account, no ads.

CoreScope shows exactly what your iPhone is doing right now — and what it was doing a moment ago.

It's a device monitor first. Five live tabs update about once a second from on-device system APIs, and every metric keeps a scrubbable 3-minute history so you can see what just happened:

• Overview — CPU, memory, battery, network and storage at a glance. • CPU & Memory — live load, 1/5/15-minute averages, memory pressure (Normal / Warn / Critical), per-core use, and a colour-coded memory breakdown. • Battery — charge state, charge source, Low Power Mode, and a 3-minute level history. • Network — active connection, IPv4, DNS, default gateway, and Wi-Fi/cellular byte totals since boot. • Storage — used/free/total capacity and an external-storage inspector for a picked folder or drive.

Then it goes further than other monitors:

• Public Identity — your public IP, on-device VPN & proxy detection, and IP-based city / ISP, resolved when you open the app. • Speed test — measure latency, download and upload against Cloudflare with one tap. • Hardware Check — a guided used-phone inspection: screen dead-pixels, touch dead-zones, accelerometer, gyroscope, compass, proximity, haptics and speaker, ending in a shareable report.

CoreScope is honest about the iOS sandbox — values the system doesn't expose to third-party apps are marked unavailable rather than faked. No account. No paywall. No ads. No analytics or trackers.
