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.
