GitUp

very nice UI. Too bad it is only available for Mac

Git just celebrated its 10 years anniversary, but most engineers are still confused by its intricacy (3 of the top 5 questions of all time on Stack Overflow are Git related). Since Git turns even simple actions into mystifying commands (“git add” to stage versus “git reset HEAD” to unstage anyone?), it’s no surprise users waste time, get frustrated, distract the rest of their team for help, or worse, screw up their repo! GitUp is a bet to invent a new Git interaction model that lets engineers work quickly, safely, and without headaches. It's unlike any other Git client out there from the way it’s built (it interacts directly with the Git database on disk), to the way it works (you manipulate the repository graph instead of manipulating commits). With GitUp, you get a truly efficient Git client for Mac: - A live and interactive repo graph (edit, reorder, fixup, merge commits…), - Unlimited undo / redo of almost all operations (even rebases and merges), - Time Machine like snapshots for 1-click rollbacks to previous repo states, - Features that don’t even exist natively in Git like a visual commit splitter or a unified reflog browser, - Instant search across the entire repo including diff contents, - A ridiculously fast UI, often faster than the command line. GitUp is available in Pre-Release today. Create a free GitUp account to access the community forums, advanced features in the app, and more. Give it a shot and be sure to share your feedback!

I can see this as a great helper for learners as well. As you can see, git can be very confusing and judging from your landing page, it looks like you can easily visualize what you're doing/about to do! I'll give it a shot :)
