How do I check how much Bitcoin Gold do I own?

Where can I find out how much BTG do I had at the time of the snapshot? was it in October 21? I forgot. Anyway I guess I need to check address by address on some sort of BTG blockchain explorer and sum all the different amounts I own starting since the first BTC I ever owned until the last one before the BTG snapshot was took.

What BTG explorer do you recommend to do this? I don't want to click some dodgy website. I really hate all these forks, even if it's "free money", I don't have the time to keep up with all of this mess. I would rather have BTC itself go higher than deal with these forks.
