Track performance of shares across ASX and US?

[ozi stocker]

I have some shares in an Australian company via MyWealth and also some others in Etoro, I am looking to expand my portfolio with some more Australian and international shares.

What is the best platform for combining the performance of shares across the ASX and international shares?

Id like to be able to key in how many shares I have also so I can view my profit / loss.

Thanks!
