Android Expense Tracker UI Blueprint

I’m putting together a simple yet professional Android app concept that lets users:
• log daily expenses,
• track silver, gold, and crypto investments, and
• see a quick profit-and-loss snapshot beside live price placeholders.

I only need the visual side—no coding or backend work. A clean professional style is important, with a layout that feels native on modern Android devices.

Deliver to me:
• Low-fidelity wireframes or a Figma/Adobe XD file covering the three main sections above
• Clear navigation flow between those screens
• Space marked for live price feeds so developers can hook in data later
• Basic colour palette and typography suggestions that fit the professional theme

Keep the scope light and focused; I’m after a concise blueprint I can pass straight to a development team.
