Iphone app that lets you see when someone read your txt you sent them?

I know there's a feature on the iphone that you can turn off/on that shows someone that you read their text they sent you.Obviously everyone has caught on to this feature and turned it off so its rare your able to see if the person read the text you sent them… I'm curious is there an app i can download that will show me if the person i sent a text msg to has read/opened it, not just delievered… There has to be, there's an app for everything else… Thank you

There isn't because it violates the privacy of the consumer. Without their consent you can't see if they read your message

There's no such app, stop being a creeper, if you sent a text, unless they are dead, they probably read it and just felt like not responding, stop being such a loser
