Flipgrid is now a part of Microsoft and as a result, have made Fligrid free to use for all educators and students. Flipgrid has always been free to use, but had paid premium features. Well no longer, every educational account has now been upgraded to Flipgrid Classroom and those that had already purchased a subscription will be refunded a prorated refund.
Hopefully, we might even see in the future some integration with Fligrid and Office 365. Below is a video of the announcement of Flipgrid joining the Microsoft family by Microsoft CEO Satya Nadella.
