Balance forecasting is part of the app! The app has been working well for me, I have since unsubscribed from Copilot. I think the amount of setup will depend on your spending pattern. Obviously, the more transaction data, the better the forecast. Otherwise a fair amount of tweaking might be needed for it to match your expectation. The MCP makes all the projections available to your agent though, so you can certainly analyze and make those tweaks through an AI chat.
