Recommend a GUI client for git?

I was looking at video reviews of git GUI clients. The best ones are pricey and we are two people occasionally editing some webpages for our business website. It’s hosted on GitLab Pages.

Can anyone recommend something straightforward? I’ll be sticking to the terminal but my colleague is new to code repositories.

Git GUI is free, but looks terrible IMO. Sublime have a nice one and it’s not subscription based, but is expensive. We are both on Mac usually.

Another alternative I considered was showing them the three terminal commands I use mainly (add, commit and push) and then let them edit from the file manager itself. But because they’ll be doing this so rarely, it might be easy to forget.

Edit: I’ve settled on a few to try out: sourcetree, fork, gitup and the one by Sublime. The conversation doesn’t have to end there, but thanks for the help. So many great answers here :)
