The FTX app(previously called Blockfolio) has this feature. The only difference is that the profit/loss number isn't displayed in the coins list; instead, you need to tap it and go to the Profit/Loss tab to see the details of your investment.
https://blockfolio.com/OK. I see it now! Am I doing something wrong? It doesn't seem to update the prices until I pull down to refresh or I go to a different window.
EDIT: Playing around with it...i like. A few things I wanted to ask you...
1) How do I edit my entry? In the profit/loss tab, I see the big "add transaction" button at the bottom, but I can't find "edit". In case I made a mistake with the info I entered, how do I edit/correct it?
2) What I mentioned above...is it me or is it not real-time in the sense that i don't have to refresh the page to see the current price?
3) It would have been pure awesome if it can list all the coins in one page/view...like my screenshot in the OP. Is there a way to do that? And if there was a home screen/float widget??...
4) How safe is it to have my exchange wallet added so it can automatically do you it?
5) In
profit/loss > trading pair > net cost... the number is (significantly) different than
profit/loss > overview > profit/loss... Why?
6) Is it me or is the UI slow/sluggish?
Thanks for your help!
