Free Memory allows you to free up runtime memory on your iPhone or iPod Touch.

The iPhone or iPod Touch comes only with 128MB of runtime memory or RAM, 256MB on the iPhone 3GS. This is not to be confused with the storage memory which is usually 8GB, 16GB or 32GB of persistent memory.

The iPhone or iPod Touch OS does not implement virtual memory, so this means that the OS does not make use of the storage memory to increase the size of memory available to running applications.

Some native applications that come with the iPhone continues to run even after you have closed them, for example, the iPod player, Phone application, Mail application and the Safari web browser.

As you continue to use your iPhone or iPod Touch, these continually running applications continue to consume limited and precious runtime memory that could otherwise be available to other applications such as games and news applications causing them to quit unexpectedly.

With the Free Memory application, you can see how much runtime memory is currently available for applications.

You can also view all the currently running applications or system processes. In the above screen shot, the iPod music player, Mail and the Phone applications are still running.

FREEING MEMORY

With Free Memory, you can make up to 40 MB free available by touching the “Free Memory” button, more than 130 MB on the iPhone 3GS.

QUICK FREE

The Quick Free mode frees memory quickly and safely. If you only need an extra boost, use Quick Free.

GAME MODE

Game Mode frees more memory than Quick Free and will take longer to complete. If you want to free as much memory as possible so you can play your favorite game, use Game Mode.

PROCESSES

Running processes are displayed in the table. To the left of each process name is the process id. If you are a developer, and have been using your iPhone or iPod Touch to debug your applications, you may notice multiple instances of your application at the bottom of the list. These are dead processes. You will have to restart your iPhone or iPod Touch to remove all of these dead processes. Or, you may use XCode to attach to the process using the process id, which will kill the dead process.

Unfortunately, the OS currently does not allow retrieving additional information about other processes, such as memory usage and cpu usage. If this was to change, we would include this information.

BATTERY LEVEL

The battery level indicates the percent of charge left in the iPhone or iPod Touch battery. Currently the OS does not return other information such as the time left remaining or time to when the battery will be fully charged. If this was to change, we would include this information.

SETTINGS

Launch on Start

When set, the app will free memory using Quick Free when you start the app.

Kill All Apps

When set, and when you use the Game Mode option, the app will keep freeing memory until Safari, Mail and iPod has closed. Sometimes this may cause the Free Memory app to close. So, please use this option with care. If the app closes unexpectedly, memory has still been freed.

Apple has demanded that we remove the feature to Free Memory from all our apps. We have decided to remove our existing Free Memory 1.5 and MemoryInfo 1.1 apps from sale. We have instead submitted Free Memory Lite and MemoryInfo Lite without the Free Memory feature.

WHAT WILL HAPPEN TO MY COPY OF FREE MEMORY 1.5?

You will still be able to use your Free Memory 1.5. Just make sure you do not delete it as you will not be able to repurchase it from the App Store.
