Does the iPhone have a feature that tells what apps you have that you use the least?

I have loaded a lot of apps for my 4 year old and my storage is maxed. I want to delete the apps that are used the least and can't figure out how…

If you double press the 'home button' (bottom button), you can slide all the way along and they are in order of the most recent apps. So if you go all the way to the end you will probably end up finding apps you haven't used in months.

Another way: Go to settings, general, usage, view all apps; then you can see all the apps you use and how much memory they are taking up.
