How do I know what apps are downloaded to my iPhone 4?
Depending on which version of iOS you are using there is different ways to check that. If you are using a new version of iOS like 7 or 8 then you can do the following or something similar.
- Open the "Settings" app.
- Go to General -> Usage -> Manage Storage (under Storage).
- Now you should soon see a list of apps installed on your iPhone.
Remember that this is only applicable for newer versions of iOS. Also, between the versions the steps can differ a bit but it is similar. Check under "General" in Settings and look carefully for something like "Usage" or "Storage".
Open Spotlight by pulling down on the home screen, then search for ".".
The first category is Applications, providing a list of applications that are installed.
