Tower is a git client that was previously available only on the mac. A Windows version is has been available as public beta for a while. We took it out for a quick spin and we really liked what we saw. A lot of care has gone into the design of the app. If you are looking for a good alternative Git client on Windows we highly recommend

this one. Also while it is in public beta the app is free to download and use. Get more information about the Windows app from the link below
