i need help finding an app

[htownsfinest]

A friend of mine used an app to figure out my screen lock pattern on my phone. He won't tell me the name of the app and I searched the market but came up empty. Does anybody know of such an app?

I'm pretty sure he is pulling your leg. There is no such app, and if there was, it would be very illegal. He probably saw you put your pattern in once, or just saw the fingerprints on the screen.
