I'm using Webbrain via the browser of Google Cardboard(tm) VR device.
And I've received a lot of positive feedback. That's definitely gives customers a new point of view on thier mindmaps. But browser mode is quite limited.
Since Google have published an SDKs for such VR (developers.google.com/vr/android/) it would be very cool to add a VR-layout for your mobile app.
What do you think?
