I am designing an Android app with 5 destinations in the bottom navigation bar. The main screen is one of them. It's a list of events and the app bar there is pretty custom - prominent with the logo, search icon, sort and a dropdown to choose a city. In other destinations I have just the regular app bar with the logo or the screen title and a "join" icon for example.
One of the destinations in the nav bar is a list of contests that the user can take a part in. This is actually the main feature in the app. The currency is points, so the user needs to know the point balance.
This is where I have the problem. I don't think I can squeeze the balance into app bars in all of the destinations - they are already full. So I was wondering if showing it only on the contest destination could be a good idea (or not - because it would not be consistent across the app). The other situation when user can take a part in a contest is from a particular event screen, so there they would not know the balance and therefore if they can afford to pay for the contest.
I kind of feel like the user should be aware of the balance at all times, but I am not 100% sure, I need to make a decision by myself (with no users) and I have no idea how to squeeze the balance value on other app bars or if it's absolutely necessary.
I attach the main screen for visualization some of the app bars that I already have in the app.
