Text Detective can detect text and read it aloud--whether it's a nearby sign, a handout, or a document.
Here's what users say about the app:
“It truly is an app among apps. Nothing I've ever used for iOS comes close.” - Andre
“Love it! Love it! Love it. I especially like the way it just keeps scanning until it finds text." - Mark
"I have had success with the app identifying labels at work. Thank you very much!" -Paul
