Quartz

Quartz is a very different application because you can’t put it in an existing category. First of all, it’s a news source, but it only sends users the most important news stories that have been curated by humans.
The user is the one that puts all the filters in place so that he gets only the news that he wants. This is where the app gets interesting. After you receive the news, you chat with the news bot, which is smart enough to provide you with more information.
Even if you don’t receive any kind of news that you might be interested in, the application will provide with a quiz to pass the time.
