Android: Your Android phone probably came with basic caller ID, but if you're like most people you still wind up with a lot of mystery calls. WhoAreYou is a free app that boosts that caller ID by filling in details that you'd miss otherwise, like the city and state of the caller and other directory information available. The app can then block calls and SMS messages from unwanted numbers, and if you get a call from an unknown number and still don't know who it is, you can use the app's reverse lookup tool to search for the caller's identity.


WhoAreYou doesn't replace your dialer, but it will pop up when you get a call with available information about the caller, but if that's not enough, you can use the number and look up the caller in the app's database. If you're being bothered by telemarketers, you can tell WhoAreYou to block them entirely. The app will even pick up the call, play a recorded "out of service" message to the caller, and hang back up, so the caller thinks your line has been disconnected.

The app works for SMS messages too. When a message from an unwanted sender comes in, you'll never know it arrived. The app is completely free, and available now at Google Play for Android devices running 2.1 or higher.
