The iPhone and iPod Touch are an amazing platform for App’s. From twitter clients to full feature games. Most of these work perfectly without a hitch but when it comes to some App’s, especially Photography App’s then it’s a different story.
Photo App’s usually use a lot more memory than other App’s and frequently go over the limit of RAM it’s allowed to use causing the iPhone to close it.

Using App’s such as System we can clean up the memory and free up a lot of free space, which some people achieve via re-booting. What would be a lot better is if you have an App that needs a lot of memory clean it up before you start the App. Maybe Apple should implement a memory cleaner which works in the background when it realises a certain amount of memory is being used that cleans it up.

Here’s a screenshot of System, an App for the iPhone/iPod Touch that free’s up memory.

As you can see System freed up about 39MB of RAM making App’s which are memory intensive work a lot better.
For a better user experience either the developers or Apple should implement this feature.
