Whats a good android app for porn?

Whats a good app that I can watch porn with but wont be discovered on my phone if I lend it to someone.

I recommend PornLockr its a free, allows you to hide it using decoys, and removes all traces of your searches from your phone. pornlockr.com

If you must... just use a browser app.... what you could do is install a second browser app and NOT put any shortcuts on your desktop... and then go into settings on the app to delete cache/browsing history when you exit the app.
