GitPoint

View repository and user information, control your notifications and even manage your issues and pull requests. Built with React Native, GitPoint is one of the most feature-rich unofficial GitHub clients that is 100% free. View and control all of your unread and participating notifications. Easily obtain repository, user and organization information with a clean and simple interface. Complete internationalization support allows you to view the app in a number of different languages. Communicate on issue/pull request conversations, apply labels and assignees, and more. With GitPoint, you can even review and merge pull requests with a design you're already familiar with. Every currently available client that I tried to use was either too simple (single-feature), required payment for the most basic of features (such as commenting on an issue) and/or didn't have the best UI.
