If you're on a mac, I can't recommend Tower enough. It's a paid app but well worth the money. Otherwise Git Kraken is a foss offering that is also excellent.
I think maybe the term you're looking for is "freeware"?
It's impossible to sing those names loudly enough.

I hate git, I don't understand git, I don't want to have to understand git, and I think the command line interface makes every UI error in the book. But SourceTree has made me like git.
