High-fidelity mobile finance app UI screenshot for a personal budget tracker. Portrait 9:16 composition with a monthly spending summary card at the top showing total spending, remaining budget and progress, followed by segmented controls for accounts and categories, a colorful donut chart, category breakdown list, recent transaction list, savings goal progress card and bottom navigation. Modern financial product style with soft white background, navy text, mint, coral, gold and blue category accents, clear numbers without exaggeration. Use generic icons and placeholder merchant names only. No bank names, no real merchant logos, no watermark, no investment return promises.
