Pretty sure HL won't work on PC
Perhaps it works for you because you have an account as such. I did have the HL watchlist on a cheap Android device but there is no longer compatibility. I haven't been able to get a watchlist from HL on my pc. It is purely a dummy account that I want (and now have with II).OK, then I am not at all sure what you want. I have a PC and happily use HL
Interactive Investor have a research account where you can create a watchlist and virtual portfolio
The II research account works pretty much the same as HL watchlists/virtual portfolio - and it seems that is not what the OP wants
