AndStatus is an Open Source low traffic social networking client with tree-like threaded conversations.
It supports different Social networks, including
GNU social (e.g. Quitter.se, LoadAverage, Vinilox, etc.), Twitter and Pump.io.
AndStatus can combine your feeds from all networks into one Timeline,
and it allows you to read and post even when you are offline.

For Android v.4.1+ devices.

Características distintivas do AndStatus:

1. Many accounts in different Social networks. Pode possuir várias contas em cada uma das redes, escrever ou responder de qualquer uma delas e partilhá-lhas entre as contas e sistemas.
2. You don't need to be online to read timelines and to post your updates: drafts and unsent posts are kept even after reboot. E serão enviadas assim que o dispositivo estiver ligado à rede.
3. Uma "Vista de conversas" conveniente.
4. "Global search" allowing you to search public messages in all networks with one query.
5. Lists of Friends and Followers, presented as User Lists and as Timelines (with the latest message of each user)
6. Sincronização de tweets/mensagens/avatars/imagens em segundo plano, se o seu dispositivo estiver ligado à rede. By default, attachments are downloaded via WiFi only.
7. Os itens em cache podem ser guardados por diversos anos ou apenas por alguns dias. Você escolhe.
8. Backup and restore accounts and messages between your devices. Own your data!
9. Livre, sem anúncios e suportado pela comunidade.
