I use the blockfolio app. Also I use coinmarketcap when working with the computer. And I follow in a telegram a couple of channels that publish the latest news about crypto. It helps me keep abreast of important events.
I just go to CMC for a big overview,,, there are so many fancy ones but they all need some app or some bookmark and I do not really have a big portfolio, I know when they moon anyway since Google will show me headlines but CMC is still the easiest even with all the issues and problems they have faced in the past,,, not like I am such a big trader.
