I use the android app Jerboa. However, I also tried the app “Thunder”, only on GitHub atm iirc. And on your profile it displayed your cumulative sum of upvotes. Funnily enough not the comments themselves, just a score. Anyways, I hope less apps track that. It breeds the worst users.

I think the closest I would want to a total score would be maybe the ability to sort my own comments by vote count when reviewing them. But you shouldn’t be able to do that on other profiles.
