IOS – CPU and RAM usage statistics for iPhone/iOS (similar to Activity Monitor)

activity-monitoriosiphonememoryperformance

Is there any (preferably free) way to view CPU and RAM usage by process (e.g. app) on iPhone without jailbreaking the device?

Activity Monitor on macOS displays

  • Process Name
  • % CPU (per core I believe)
  • CPU Time
  • Threads

and some other CPU statistics, as well as these RAM statistics:

  • Process Name
  • Memory (GB)
  • Threads

It would be great to know how to view similar statistics on iPhone.

Best Answer

I use CPU-x Dasher for this. It displays :

  • CPU usage, frequency time
  • RAM usage (free/used/reserved…)
  • Benchmark took (not that much features but it’s still a benchmark)
  • Networks/Sensors data
  • And all of this can be integrated on a widget

It’s still limited compared to some Android apps and it has a lot of ads but it’s the best I could find yet.
