Is there an iOS App that can detect Spam?

I heard there is an app for android that can detect spam email. Is there anything like that for IOS?

For me, all my email providers do a great job as I don't seem to get spam. I use iCloud with the iOS mail app, I also use the gmail app, I use the Yahoo app, and I use Outlook with my Hotmail account and I only get about 5 spam emails per month, maybe.
