SimplyTweet was a client for Twitter, the social networking website. It ran on iPhone and iPod touch. It was one of the few Twitter clients that supported push notifications. It aimed to be a full-featured application with a simple user interface.SimplyTweet was developed by Yar Hwee Boon, who said that the initial inspiration was his desire for an app that would be able to follow conversations – tweets that reply to an interesting tweet, or tweets that prompted interesting replies.
