Topics is a Universal App Template where users can browse random questions or even search them and join exciting conversations by posting/reading comments on each Topic.
This app allows users to earn special KARMA points based on created topics, posted comments and up-votes received for their topics/comments from other people.
It also has all the required report features for inappropriate topics, comments and/or users needed to pass the submission’s review for the App Store.

Since its backend is by Parse Server, you don’t have to buy any domain/hosting, there are NO PHP files to upload to a web server so you’ll save some money for server side.

Yes, I always update my apps to the latest version of the IDE.

Why do I need to have login from Apple Account in the app?
