Local Database, Local Settings

[Alexj17]

Hey All

All my previous Apps have used external databases and stored the user settings etc there. Now i am making a much smaller and easier App (which doesn't even require the net to use now).

I am not hoping to have a local database and also a place to store their settings and defaults.

I have had a look around and found that SQLite and NSUserDefaults comes up a lot. Can anyone give me more information about this. Is this what i am after. And how do they work (in terms of theory and not code)?

Thanks
Alex
