You can try using coinmarketcap, blockfolio, or cointracker but personally I don't use any of those app to track the price of cryptocurrencies anymore, I prefer using the exchange price chart so that I will get accurate amount of profit whenever I want sell a specific coin for usd or Bitcoin. The exchanges that we use and those apps/websites that shows live price of cryptocurrencies have different rates so I suggest that better not rely your investments on those apps/websites to avoid disappointments and only use price charts from exchanges you use.
