Vision is codename for our website https://ecency.com. Ecency is powered by Hive, so when you using Ecency you are using Hive, we just have different codenames to help us and others to recognize which product we are talking about. Vision is our website, Mobile is our mobile app, Surfer is our desktop app. Unnecessary complication perhaps, we will consider just calling them website, mobile and desktop apps in future updates. 😊
