Just released my first ambitious App! Feedback appreciated

The idea is to create a hub for learning how to invest with fake money. I plan on adding more features that will help people learn and practice. If you have any ideas, feedback, or tips I would love to hear it as I want to implement features people want and need to help them learn. In the future I want to add articles/ learning material, challenges, etc.

For now, this is just the MVP with basic functionality to buy/sell stocks. Also, it's iOS only but will release to Android in the future.
