App.net  hit the headlines recently as it beat its crowdfunding goal  and successfully launched as a paid-for alternative social media app like Twitter, but lacking adverts.

It's an alpha test version, but it is free from the Play Store.
Twitter, App.net's most similar rival, has recently angered some  of its developer community by aggressively shutting down access to its API. It's a move some say is draconian, but it's easy to argue  that Twitter--which has hundreds of millions of users--is merely acting to protect its business and its revenue streams.
