I started to invest. Any tips / advice to share how to track / monitor on the progress or status of my portfolio (phone app / Excel)?

I use the JStock widget on android. Super useful and user friendly!

I use StockMarketEye for many years... does the job well

I invest in stocks in US and SG.

In my Android phone, I use this app called Uplift, they are able to track companies from any stock markets. And they can notify you when it is below or above the price you set.

I use both StocksCafe and Yahoo Finance. Both are good but I kind of like Yahoo Finance's widget better in terms of design.
