Is there an app to c if someone has read your text?

I have an iPhone and was wondering I there's an app or a setting that shows u when someone else has read/opened your text? And hasn't replied yet.

No there isn't. If they have the option and select "send read receipts" than you can see if they read it or not. But if they don't have it on, than you can't!

Yes there actually is one. I don't know much about it but my friend has it on his iphone

just keep researching about it

please answer mine
