PlomGit

PlomGit is a simple open source git client. It supports enough basic functionality that programmers can use it for version controlling their personal files. Repositories are accessible through the Files app, so you can use other apps to work with your repositories' files. PlomGit only supports fetching and pushing through http(s). Account passwords or tokens can be stored separately from repositories, so that repositories can easily share them.
Note: When using PlomGit with GitHub, you cannot use your normal GitHub password with PlomGit. You must go into the settings of the GitHub website and generate a Personal Access Token that PlomGit can use instead.
