Description
CPU Runner is a real-time diagnostics tool for iPhone and iPad. Built for developers debugging app performance, IT support diagnosing devices, and curious users who want to know what's actually happening on their
hardware.
No tracking. No fake numbers. Only public iOS APIs.
FIVE LIVE MODULES
CPU
Per-core load via host_processor_info
Overall load with thermal-state badge (Nominal / Fair / Serious / Critical)
Single-core and multi-core benchmarks with progress tracking
24-hour history
Device
Chip identifier, iOS version, kernel build
Memory breakdown: active / inactive / free / wired / compressed
Memory pressure indicator
Storage, resolution, ProMotion refresh rate, color gamut, boot time
Shareable summary card
GPU
Metal device family and capabilities
Raytracing, function pointers, dynamic libraries support
Argument buffer tier, R/W texture tier, max threadgroup memory
FMA throughput benchmark in GFLOPS
Network
Live download and upload throughput (app-attributed, honestly labeled)
Cellular radio: 5G, LTE
NWPath flags: expensive, constrained, IPv4/IPv6
Local IPv4 address
Latency to a configurable host
24-hour history with CSV export
Battery
Charge level, state, Low Power Mode
24-hour battery curve
Deep link to Settings for battery health
11 HARDWARE TESTS
For technicians and curious users:
Display: solid colors, gradients, grids, SMPTE color bars
Multi-Touch: up to 11 simultaneous touches with force readout
Touch Coverage: paint the screen to find dead zones
Haptics: all 8 feedback types
Speaker Tone: sine waves with L/R channel routing
Microphone: live input meter
Motion Sensors: accelerometer, gyroscope, magnetometer, attitude
Barometer: altitude and atmospheric pressure
Proximity Sensor
Camera: front/back preview with torch
GPS / Compass: coordinates, altitude, heading, accuracy
HOME SCREEN WIDGETS
CPU Load (small and medium) with per-core bars
Memory Pressure with category breakdown
Device Info: chip, RAM, free storage, uptime
HONEST DESIGN
CPU Runner does NOT:
Pretend to "clean RAM" or "boost CPU" - iOS does not expose those APIs, and apps that claim to are misleading users
Read battery health or cycle count - these are gated behind private APIs
Measure system-wide network throughput - only app-attributed traffic is available
Track you. Nothing leaves your device.
All measurements come from documented public Mach, Metal, Network, and UIKit APIs.
OPTIMIZED FOR IPAD
Multi-column NavigationSplitView, sidebar navigation, gorgeous in landscape.
REQUIREMENTS
iOS 17 or later. Some metrics (per-core CPU, hardware sensors) require a real device - simulators return synthetic values.
