I personally use the Blockfolio app on my android phone to track my portfolio. I think it also available on IOS. You will get almost every token/coin on this app and also almost every exchanger in the market is available there. You can sync your exchanger account with this app. I synched my binance account on the app using binance Api key. It's 100% safe for me. I don't need to add every token manually here it automatically updates here with the help of API.
