Tweet Later is a web app that allows users to manage multiple Twitter accounts and schedule tweets for a particular time and day.

Features:

• multiple Twitter account management
• all Twitter operations supported
• schedule and manage future tweets
• configure follow/unfollow and DM

The Good:

Tweet Later is an excellent “productivity tool” for Twitter, allowing for multiple Twitter accounts and the scheduling of tweets. It also allows you to auto-follow those who follow your account and provides an auto-welcome feature to send a custom message to new followers via DM or in the public timeline. You can also schedule and publish tweets that don’t go to Twitter, but rather to your personal tweet stream via RSS, XML or javascript. 

The Not-so-Good:

While the features and functionality of Tweet Later are great, the UI feels a little bit “clunky” and perhaps not as slick or shiny as some others out there. That is more a “style” complaint rather than a “substance” complaint. Tweet Later definitely gets the job done.
