Every app with read receipts requires both people to have the same 3rd part app since sms doesn't have that feature. Even on iMessage you don't get a confirmation when you text an android user because then the app is sending an sms instead of an iMessage.
Im actually looking for same thing. But I gotta add Babble that youre not exactly correct. It really depends on the phone. I have an Alcatel Fierce1 & I get read reports but on group messages only. I know others whose phone gets them. Since mine doesnt for individuals texts id like an app that provides them as well
