Just finished and submitted my Twitter application to the AppStore. It's called EasyTweet, and it allows you to easily compose and send a Twitter update without the fuss and hassle of reading other people's tweets.
It's useful for those times that you just want to send an update out quickly on Twitter. Since's it just updates, it takes up less than 1 kb of internet bandwidth, which is a great benefit to those people who are not on an unlimited data plan.
I'll post again once the app get's approved! Would appreciate your support!
