A fast, native system monitor for iPhone and iPad.
Per-core CPU load, memory, storage, hardware diagnostics and widgets — all at a glance.
CPU Cores turns low-level system readings into a clean, responsive dashboard designed for both iPhone and iPad. It is lightweight, fully native and processes device statistics locally.
- Live CPU monitoring — total usage and individual load for every logical core.
- Memory breakdown — used, free, active, inactive and wired RAM.
- Storage overview — total, used and available device capacity.
- Home Screen widgets — small, medium and large layouts on iOS 14 and later.
- Lock Screen widgets — circular, rectangular and inline families on iOS 16 and later.
- Hardware details — model, board, architecture, core count, RAM, display, storage, thermal state and uptime.
- Battery diagnostics — health, wear, maximum capacity, design capacity and cycle count on compatible privileged installations.
- System cleanup tools — controlled memory pressure and APFS purge requests, always leaving the final decision to iOS.
- Configurable widget refresh — choose an interval from 1,000 to 5,000 ms for the silent-audio keep-alive.
- Ten localizations — English, Italian, German, Spanish, French, Japanese, Polish, Russian, Simplified Chinese and Traditional Chinese.
| Feature | Requirement |
|---|---|
| App and Home Screen widgets | iOS or iPadOS 14.0+ |
| Lock Screen widgets | iOS or iPadOS 16.0+ |
| Standard system statistics | Any supported installation method |
| Advanced battery diagnostics | TrollStore, TrollStore Lite with an active jailbreak, or another environment granting the required private entitlements |
Important
Raw battery values are not exposed by the public iOS SDK. They may appear as Unavailable when CPU Cores is installed through a standard sideloading method, or when the OS/device does not expose the expected IOKit properties.
Download the current packages from GitHub Releases.
Use the unsigned .ipa release asset with a compatible signing or installation tool, such as:
- AltStore or SideStore
- Sideloadly
- AppSync Unified on a jailbroken device
This build provides the complete dashboard and widgets, but advanced battery fields normally remain unavailable because Apple does not grant third-party sideloaded apps the required private entitlements.
Install the .tipa release asset with TrollStore. This package is ad-hoc signed with the private battery and IOKit entitlements used by the hardware diagnostics.
TrollStore Lite can provide equivalent privileged access while its supporting jailbreak is active. Classic TrollStore remains the preferred option on versions supported by its CoreTrust installation method because it does not depend on an active jailbreak session.
- macOS
- A full Xcode installation with the iOS SDK
- Command Line Tools selected for that Xcode installation
Clone the repository and run the all-in-one build script:
git clone https://github.com/Lampadina17/CpuCores.git
cd CpuCores
./Scripts/build-all.sh BuildThe project is compiled only once and both distributable packages are created inside Build/:
Build/
├── CpuCores-unsigned.ipa
└── CpuCores-TrollStore.tipa
The script does not modify Xcode project signing settings. It verifies the unsigned payload, the widget extension, the TrollStore signature and the required entitlements before producing the final archives.
To develop or run a normally signed debug build, open CpuCores.xcodeproj, select the CpuCores scheme and choose your development team in Xcode.
CPU Cores can use a silent, mixable audio session to keep requesting WidgetKit reloads while the app remains active in the background. The interval is configurable from the app settings.
This is an experimental sideload-oriented mechanism: the selected interval controls how often CPU Cores requests a reload, not a guaranteed WidgetKit update rate. iOS can throttle or suspend background work depending on device conditions, power state and system policy.
CPU Cores has no analytics or telemetry. System readings are calculated on the device and are not sent to a remote service.
Bug reports, compatibility results and focused pull requests are welcome. When reporting a device-specific issue, include:
- device model and iOS/iPadOS version;
- installation method;
- jailbreak and TrollStore version, when applicable;
- whether the issue also occurs after a clean reboot or reinstall.
