Start up

Start up Gravity and you see the option of adding a twitter or Laconica account. Add you twitter account. You can also add multiple accounts. Once you set up an account, Gravity will wait for you to confirm going online, useful as all the avatars downloaded could run up your data cost and even then there’s a counter on the screen showing the data used in the current online session.

Online

Once online, you see a number of tabs. The first tab is your current timeline – showing tweets or updates from all of your contacts, just like the default view on Twitter. The post is shown with user name and his avatar and you can easily do number of tasks such as reply, retweet etc.

From your timeline, you can scroll to the right once more to see a list of any updates from anyone that includes an @reply to you. This is helpful to somewhat carry on a conversation on Twitter. The next tab over shows any direct messages you have received. Yet another click to the right gives you a list of your updates, and another click shows the direct messages you have sent to other people. The last click to the right brings you to a list of your favorite tweets, if you use that feature.

Also there is a search pane and an images section. The image section integrates with your smartphone’s gallery, and any picture taken can be uploaded to the popular third party web site Twitpic and have a twitter message with a link to the photo embedded. So one click to take a picture, one to upload to Twitpic, and one to post the Twitter message about it.

For Symbian 60 v5 users,  Gravity is fully touch-enabled across the entire interface along with kinetic scrolling, so that flicking down the long lists carries on and slows after a quick flick, rather than coming to a dead stop after the scrolling move. This is another rmarkable feature of Gravity.
