I'm 14 and launching my first finance app tomorrow . What’s your best advice?

Hello! Tomorrow Im launching my finance app on Product Hunt, does anyone have any advice? I spent the last 10 or 11 months working on this app (the picture), and want to know how to gain some users. And if anyone is interested on my product-hunt-project post thing tommorrow, you can just search "Budgefy" (I think).
