iCaughtU Pro works well, especially when paired with a passcode for added security. And the price point ($2.50 per device) is great, even for SMB. The caveat? iOS devices must be jailbroken in order to install the app. This is a deal breaker for business users, especially Enterprise users that are typically forbidden (and in some cases blocked outright from doing so) by IT.

Thank You for the heads-up on iCaughtU Pro!
