Currents is a free software developed by Google for internal enterprise communication. It is one of the many products that the software giant offers to G Suite users. The app enables discussions and interactions across organizations while you are in the office or on the go. With this, you and your team can exchange ideas, as well as documents, without flooding your email inbox. The app lets you organize the content by relevance or time, to make sure that the most important one comes first. Note, however, that the app is only available to G Suite customers.
