## What is CoreScope?

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.
