iOS Sms Spoofing App

I used too have an iPhone sms spoofing app. I used it for social engineering. I Recently reset my phone and cannot remember the name of this app. It was a paid app that spoofed text messages. I want too say it was called "line in" or "line out" but I have had no luck in searching for it. Wondering if any fellow iPhone users might remember the name. I did purchase texts for the app. Is it possible for me to search for my app that way? Or am I just retarded?
