How much memory is my iphone application using (from Simulator)

I know it has something to do with tools, but it seems to be confused and googled for tools, it doesn't help much.

I would like to know how well my application is performing, such as how much memory it is using. I just don't know where to find something like: "Once we can say with the simulator that the application will use xx MB of RAM on a real iphone device."

I need help on how to get this information.

You should not check your memory usage in the simulator for a number of reasons, some of which are:

  • The simulator runs on your computer, not your phone, so the maximum storage is the same as the bar installed on your Mac.
  • The simulator and your application, when building from the simulator SDK, do not use the same libraries as on the device and, as a result, may use a different amount of memory.


However, if you can start the device, you should use the Monitor Monitor and Object Allocations tools in the tools to monitor your memory usage.

You should use Run / With Performance Tools / Object Allocations. The memory used will be displayed on the graphs.



And then you check the box "Created and stationary" to see what objects are in memory.
