This application is a very simple client for the social / microblogging service Twitter. It works on Android phones (like the T-Mobile G1).

The mobile version of the Twitter web site at m.twitter.com does almost everything you would want, but it can’t notify you about new updates as they happen, which is where nanoTweeter comes in. It runs in the background and regularly checks for new updates and messages. When someone you follow posts a new tweet it notifies you using the usual Android notification system. Tapping one of the notifications sends you to the Twitter page for that tweet.
