CAPerfHUD

Enable system-wide performance HUD for iOS 13+. Requires jailbreak or TrollStore.

C4EBC522-2C77-4D92-81D0-F5B38C1DF0D0

Notes

  • iOS 12 (and below?) support is possible, but I couldn't find any similar entitlement, since com.apple.QuartzCore.debug was not there.
  • Some measurements may not work (frequencies, power consumption, display EDR).
  • Change lasts until backboardd restarts (respring)

Source code structure

  • CAPerfHUDApp: Application for AppSync/TrollStore.
  • CAPerfHUDModule: CCSupport module for jailbroken devices.
  • CAPerfHUDModule/CADebugHelper: helper executable to get/set debug values because SpringBoard isn't entitled to do so.

Building

export THEOS=/path/to/theos

# Build ipa for AppSync/TrollStore
make -C CAPerfHUDApp package PACKAGE_FORMAT=ipa

# Before building for the opposite deb package scheme, make sure to add "clean" before "package"

# Build rootful deb for CCSupport
make -C CAPerfHUDModule package

# Build rootless deb for CCSupport
make -C CAPerfHUDModule package THEOS_PACKAGE_SCHEME=rootless
