Working Copy is a very powerful, fully featured Git Client for iOS.
I use Working Copy to edit this blog on my phone. Because this blog is also a git repository, I can edit content and code. I just commit and push any changes to my Github repository and see them live.
Making huge changes on mobile isn’t recommended because there’s no way to test on a local environment first, but there’s something really powerful about being able to make code changes on the go. I admit it’s not the most user friendly blogging solution, but one that works well for me. I like the control and flexibility of blogging on Github pages, and the freedom of doing things on the go using Working Copy.
Working copy can be downloaded on the App Store.
