Basefolio is a free cryptocurrency portfolio tracker which I wrote for my own use. If you are one of 13+ million of Coinbase/GDAX users and are tired of manually entering all transactions this app is for you. Feature-rich dashboard modelled after a great stock-trading app by Robinhood. Backend calculations to give you a complete view of your P/L both for open and closed positions.
This app uses the official Coinbase and GDAX API to fetch transactions and cryptocompare.com API to fetch historical and spot prices of cryptocurrencies.
