Just wanted to introduce a project I have been working on. It is called Fig, and it is native Discourse client for iOS/iPadOS.
Fig is available for free on the App Store.
Most of the functions and features in Fig are free and will be plentiful for most users. Fig+ subscription allows access to private communities, unlimited number of posts and communities, free app icons, and future premium features. It will also help sustain the continuous development of Fig.
