One such tool isĀ SourceTree, a free Git client for Windows or Mac. It provides an nice visual interface between you and Git, no more command line!
Usually many code editors today are using a git plugin that you can use. Try to find if there is an intergrated Git versioning system in your code editor. Personally would reccoment for Mac using the Visual Studio Code which has git integrated
Another tool which you could use is GitHub Desktop. The application has a better user experience and user interface over SourceTree. The layout of the GitHub Desktop application is simple and straightforward with an uncluttered interface, making it perfect for the beginner, though still including more powerful options for the advanced developer.
Thanks for sharing! One more useful feature this tool provides is detailed branching diagrams. It helps to understand the progress of the team faster. Might be helpful for beginners to learn the branching idea of git as well.
