I've used 3rd party, free apps like Yahoo Finance and others in the past, but was concerned about security.

Once I moved all our investment accounts to Fidelity, we've relied on their app to keep track of everything, as well as for research and news.

For other news, still use Seeking alpha, Yahoo Finance, and WSJ.

The main problem with "free" is that it still costs in indirect ways - your information may be sold to other firms.

And some of those previously free apps and access are now limited, or may ask you to start paying a subscription.

So, in a word, use the app your investment firm offers to keep track of your investments.
