What's a wonderfully organized Android app for keeping track of my investments, like having a card catalog in my pocket, dear?

Well, after trying a few different apps, I've settled on the Fidelity Investments app, and I must say, it's delightfully intuitive. The categorization system is brilliant; it's like having a perfectly organized card catalog right in my pocket! I can easily check my daily status and make changes when I need to. I've been able to keep a much closer eye on my retirement accounts and other investments since I started using it. Who knew my phone could do this? I even figured out three new features this week! I find it so useful for information management, and it's been a great help in planning my financial strategy. It's just so wonderfully organized!
