Silicon Scope

Live per-core CPU graphs, memory, storage, network, battery, and a built-in CPU, memory, and GPU benchmark. No network requests, no tracking, nothing leaves your iPhone.

Silicon Scope is a system monitor for iPhone that shows what your hardware is actually doing, in real time.

See total processor load and a live graph for every logical core, split by performance and efficiency cluster so you can tell which kind of core is doing the work. Watch memory, storage, battery, and network activity update as they happen, and run a built-in benchmark when you want a number instead of a graph.

Live monitoring:

• System-wide CPU load with a graph per logical core
• Performance and efficiency core clusters identified separately
• Network throughput, local IP and IPv6 address, and interface details
• Storage capacity and available space
• Battery charge, state, Low Power Mode, and thermal state
• Metal graphics device capabilities and this app's allocation
• Live thread list for the app itself, with names and CPU share

Benchmark:

• Integer throughput and single-core floating point
• Multi-core scaling across every core
• Memory bandwidth
• Metal compute throughput on the GPU

A run takes a few seconds and reports raw units, GFLOPS, GB/s, and operations per second, alongside an index score. Results are stored on device so you can compare runs over time. The thermal state and Low Power Mode at the time of each run are recorded with the result, because both change what the numbers mean.

Six appearances are included: Light, Ocean, Violet, Mint, Sunset, and Graphite. Refresh interval, chart history, units, and layout density are all adjustable.

Privacy:

Silicon Scope makes no network requests. Nothing is uploaded, no account is required, and there is no analytics, tracking, or advertising of any kind. Every reading stays on your iPhone.

A note on what iOS allows:

iOS does not give apps access to other apps' processes, so the thread list covers Silicon Scope itself rather than the whole system. iOS also keeps GPU utilization and battery capacity and cycle count private, so the Graphics section reports Metal device capabilities and this app's allocation, and the Battery section reports charge, state, and thermal condition. Everything shown is measured on device, and anything iOS does not report is labeled rather than estimated.
