Best app to track holdings and performance?

I am looking for that too, 1 seedly member told me ifast gm.

Hey Dylan! I would recommend StocksCafe. They allow you to keep track of multiple stocks with different currency, it also allow you to input the comission charges and etc. such that you can get the true value of your stocks.

However, it also doesn't link to your IBKR or other brokerages. What I like about it is that it will show me a daily report to know what I have gain or loss. It is rather good for long term stocks tracking.

Hope this helps!
