I'm using Coingecko and Coinmarketcap and since I have one portfolio that comprises new tokens there are coins that are not on Coinmarketcap and there are coins that are not on Coingecko, these are the best tool with varied portfolios because you can create as many portfolios as you like and if there's an update of the price and additional information about the coin it will be automatically added not only that both have a Playstore version so go for it you will like the experience.
