How-to setup project


In v3+, we plan to launch Castcle Features in Castcle application, including Castcle Photo and Castcle Watch, which will provide the richer user experiences than a simple content feed reading in v1. See examples below.


In v2+, the additional Castcle Circles, not only For You circle, will be available. Each Castcle Circle is designed to represent different social bubble. For exmaple, when user navigates to Friends circle, he/she will only see contents posted by his/her family and friends. Then, when he/she changes to Following circle, he/she will see a flood of contents that he/she subscribes to. There are many more circles that we plan to provide such as Now, a circle which prioritize new contents to come first, Topics, a circle that feed contents on the topics that user interests, etc.

While Castcle Application is still under Work in Progress, you can see the demo of v3
which we plan to release in the first quarter of
Y2022 here.

The Circle Experience: Let’s Burst our Social Bubbles

Since Castcle Circle is designed to represent user’s social bubble (see the explanation here), we intentionally design the application UX letting individual user change circle, navigate through social bubbles, by swiping left or right on the screen. This will allow user to jump from one social bubble to other social bubbles easily, resulting in reducing the Echo Chamber effect, as shown in the image on the left hand side.
Features Examples: Feed, Photo and Watch
Feed Photo Watch
