Anders Borum Developer Tools
Git client - Working Copy is a developer tools app by Anders Borum. Below are its 6 current App Store screenshots.
Access Git repositories on the go. Clone, edit, commit and push while allowing other apps access to repositories. Git is a important part of our work-life and iOS can take part in this. The ability to commit even when offline has added utility on a device that moves in and out of network coverage. Cloning repositories gets you a local copy on your iOS device with commits for all branches. You can browse the content from within the app and make changes. Other applications supporting the Files app, WebDAV or x-callback-url has access to these files. Changes made can be committed and the commits can in turn be pushed back to the remote.
