1) I use an iphone app call coinstats which allows you to tap into the API of the larger exchanges and track portfolio value. http://coin-stats.com/
2) I created a google sheet for myself to which I add each transaction I do (basically a ledger) with a summary tab which tracks my actual holding and uses the Cryptofinance google sheets add-on to determine the current market value in USD of each coin. https://jbuty.com/how-to-get-crypto-currencies-rates-and-more-in-google-sheet-1a57e571bc14
