We recently set up an OppiaMobile Community site (https://community.oppia-mobile.org/), for discussions on all the different aspects of OppiaMobile, getting help and support, ideas for new features and integrations, UI and UX designs, along with the core development and questions about how to implement OppiaMobile.
So if you have any questions about Oppia, or want to see the latest discussions, then please sign up to the community site (it’s free!).
For any queries/feedback about the OppiaMobile Community site, then please post them in the Community Feedback category (https://community.oppia-mobile.org/c/community-feedback).
