The Apple iPhone is a powerful mobile device that runs on a powerful operating system. There are over 35,000 apps for the iPhone, including, stunning graphics, effects, and ‘free memory’. The Free Memory on an iPhone can be increased by restarting the device once per day. You could be running an application while listening to songs and definitely the application would have crashed. This has happened to several users and how it can be avoided. 
Generally, your iPhones memory resources are eaten up when you run programs and close them. The Free memory application allows you to free the runtime memory on the iPhone. Now, Runtime memory is the memory required to run the iPhone processes. The iPhone comes with a 128 mb runtime. Due to large requirement of system processes, there are only few mb’s left for running the applications. The low availability of runtime memory to run those particular applications results in crashing, hanging, safari suddenly quitting etc.
There are several applications including, iPod player, Phone application, Mail application and the Safari Web Browser that run continuously in the background even when closed and this is the reason the iPhone suffers with crashing applications. Therefore, by increasing Free memory, it allows you to run your applications and processes without any problems like hang and crashing. Also one thing I noticed in this application is that after freeing the memory the phone works much faster and the game speed improves, drastically.
How to Apply:
As you open the application you will see a button ‘Free Memory’ and above that you will see the available free memory which is already calculated as you open the application and tap on the button and the runtime memory would be freed. So there’s no need to reboot your iPhone again and again if your application crashes or hangs, just open the app and click free memory and your problem would be solved within seconds. The other feature in the new version is to see the processes which are currently running on the iPhone. It also shows the battery level of the iPhone in percentage mode.
IMPORTANT NOTE to users with OS 2.2: If you have less than 4 MB available, freeing memory may take about 1-2 minutes, or it may cause a reset.
