Android only: Android’s built-in lock screen patterns are great for securing your phone, but they leave finger smudges on your screen that give away your pattern. Security app WhisperCore fixes this problem by making you wipe away those smudges to unlock your phone.
While you could always just wipe off your screen every time you lock it back up, it’s easy to forget and unknowingly give up your lock pattern. WhisperCore solves this problem by presenting you with a pattern or PIN unlock screen, then forcing you to wipe your finger down the screen before it’ll unlock. This final wipe will erase all traces of your PIN or lock pattern, so no one will be the wiser, and you’ll never forget to cover your tracks.
WhisperCore is free, but unfortunately only available for the Nexus One and the Nexus S. They’re looking to support more devices soon, though, and it was so clever we just had to post it. Furthermore, it’s a good reminder that Android’s pattern unlock isn’t very secure, and you’ll always want to wipe those smudges off your phone when you put it away.
