Flatly
Household finance apps feel like tax software. Flatly is for flatmates in their twenties — split bills, share tasks, settle up without a spreadsheet.
Mapped the core flows first: onboarding a household, adding a bill, logging an expense, settling up. Home screen answers 'what do I owe and what do I have to do' in one glance; every other screen is one tap from there. Designed empty, loading, error and 'you're all square' states before any hero screen.
Native-feel components — sheet-based add flows, chunky primary CTA docked to the thumb zone, oversized status chips for bills-due. Warm off-white canvas (never grey), 20px card radii, per-housemate avatar chips in muted olive, mustard and burnt-orange.
Home, bills, tasks, expenses, settle-up and household setup flows — designed as a coherent product with a shared component library, spacing scale and interaction patterns.
