Thank you for
reaching out on the community and telling us about your issue. The mobile app does show bill reminders that you have set on your desktop but you're not able to make bill reminders on the app. It'd be its own transaction.
As for when it comes to the investments there's quite a few things it shows between current price, 52 wk highs and lows etc. I would actually suggest trying it out first to see if it's something that would work for you to help you keep track of your investments. If you end up not liking it you can always turn the feature off.
Let me know if this helps you out!
