hAppy is yet another App.net client.
hAppy was designed to be fast, easy to use, highly accessible and nice to look at. It supports the core features of App.net like unified stream, global stream, mentions, nice profile page, follow/unfollow, nice screen with your followers and the people you are following, mute, search for users, post, repost, star, conversations, private messages, read and write in patter rooms, drafts. In addition it has image sharing via dropbox and different fonts. And it is highly accessible.
You can get push for hAppy via ch.eer.io.
If you find bugs or have feature requests you can also mail me or write me a post or a private message on ADN.
hAppy isn't free anymore because some people got the impression that every ADN client has to be free. That is wrong!
