This the question which is already asked a lot of times in this forum. Better to use search function to find them before creating new topic.
This advice is for all the members not only for you though.
Btw blockfolio app is one of the best price and portfolio tracker in crypto. Many people are using it and I used it before. I have good experience there in past maybe it's now more beautiful after updating.
I used coinmarketcap web site before. It was also a good one for me. recently there is an user-friendly mobile app for coinmarketcap.
Now talking about recently what I using. Tbh those things depend on the nature of you. And it come for different time in different purposes. In past I was active in trading and I felt those apps is useful for me. But now I am less active in trading and very happy with the binance mobile app. If I think about to check the bitcoin price just visit it and see, also try to see altcoins price which I holding during the time.
