This is a list of notable Twitter services and applications. These various services and applications are designed to work with or enhance the micro-blogging service Twitter. They are designed with various goals - many aim to improve Twitter's functionality while others set out to make the service more accessible, particularly from other devices. Some applications allow users to send messages (called tweets) directly while others give users the ability to create more complex tweets which they then have to manually post through Twitter itself.
