Mobileways updated Gravity, a Twitter app on the S60, to version 1.17 on May 4th. I love this app even more now that it supports Twitter groups. If you follow a lot of people on Twitter, groups make it easier for you to organize the tweets you read. Many people like Gravity for several reasons, but this functionality makes it a must-have app for S60 Twitter power users.

Groups is one of the most demanded features for Twitter, allowing members to focus on different sets of people they’re following. For example, you could create groups for celebrities, colleagues at work, friends in real life, family members, and so on.

Twitter itself does not provide a Groups feature so users rely on third party applications to implement it. Tweetdeck is a popular desktop application because of this function and Gravity just implemented it with their latest update.

I wrote in my original review of Gravity that that it kept closing randomly while using it. I don’t see that problem anymore after several updates. You can do this directly from the application itself, which is impressive. The application costs $9.95.
