Automatic call recorder on phone. When your talking to tradies, consultants, PM etc etc and they sometimes like to talk real fast or use lingo your not 100% sure of at the time so it can go over your head. Or they are explaining a process you need to do and their mouthing it off at 100 miles an hour expecting you to get it all down. yeah right. So all my calls are recorded automatically from an App in Samsung galaxy. Can play back and listen to, etc then delete. Don't know about the legality of it all but common, use common sense, just delete it when your done and don't do anything stupid. Anyway I have found it useful, others might too.
