Xpire

Xpire is a Twitter tool to schedules tweets that will then self-destruct after a certain amount of time. With this tool, then, you can share transient or temporary information via Twitter without having your messages remain forever engraved on your timeline.

Although this is Xpire's main feature, it's not the only one. Once you log in with your Twitter account, Xpire becomes a client that can be used to perform many other actions, such as managing your followers or taking a look at your past tweets.

Another very interesting feature of Xpire is the ability to calculate your 'social score', a measure of how much exposure you get via Twitter. If you're not happy with the result of this analysis, you can eliminate many tweets at once in order to seem more discreet on your timeline.

Xpire is an interesting app for Twitter users concerned about their privacy or their exposure on the network, since it allows full control over what information stays on Twitter and what information does not.
