Google is collaborating with Fitbit across wearables and digital health.

As part of the deal, Fitbit will use Google Cloud as their preferred cloud provider and will be using Google's Cloud Healthcare API to provide an interoperability solution that enables their users to collaborate on care with their own healthcare providers.

For example, using Cloud Healthcare API with Fitbit's newly acquired Twine Health platform. The two companies will also be exploring how Google Cloud's machine learning APIs can help them uncover deeper insights.

To date, Fitbit has sold more than 76 million devices, built a community of more than 25 million active users and has one of the world's largest health and fitness databases.
