CPU-Kit: device information and diagnostics for iPhone and Android.

CPU-Kit reports detailed information about the phone it runs on — the chipset and process node, GPU configuration, RAM type and frequency, battery state, and readings from the on-device sensors. The interface and feature set are the same on iOS and Android.

CPU-Kit — Device Info & Monitor

★★★★★ 4.9 · App Store + Google Play · by AI Builder

CPU-Kit is a hardware information app for iPhone and Android. It reports the SoC and GPU configuration, RAM type and channel layout, battery design and current capacity, sensor readings, and includes a set of on-device diagnostic checks for the display, speakers, microphone, sensors and connectivity. It uses only the standard system APIs that Apple and Google make available to apps, so it works on stock iOS and Android.

What CPU-Kit reports.

  • SoC and GPU. Chipset name, process node, performance and efficiency core layout, and GPU model with core count where the OS exposes it.
  • Memory. RAM type, channel configuration and current usage.
  • Battery. Design capacity, current maximum capacity and cycle count (cycle count is available on iPhone 15 and later, where iOS exposes it natively, and on Android devices that report it).
  • Sensors and diagnostics. Readings from the available sensors plus a small set of on-device checks for the display, speakers, microphone and connectivity radios.
  • Same interface on both platforms. If you switch between iPhone and Android, the layout and labels stay the same.
