Metwit is a crowdsourced API platform that provides third party applications the ability to integrate media-rich local weather and environmental data that is hyperlocal and in real-time. The Metwit API Platform collects weather information from Twitter, Instagram, NOAA and other sources which makes it possible for third party applications to use tweets, photos, and metatags to provide users accurate and interactive local weather information.
At Google I/O 2016, Google announced the Awareness API that would enable apps to use and react to a user's context. Then, the API was available to a limited pool of integration partners. Google has now opened the API to all developers so all apps can leverage context like location and activity.
