ZeroInbox

Inboxes pile up faster than anyone can clear them, and the usual cleanup tools are tedious one-at-a-time slogs. People bounce off email triage because it feels like work with no payoff. The challenge was to make decluttering fast, batchable, and genuinely satisfying enough that users come back to it.

ZeroInbox groups Gmail by sender so a single swipe can act on every message from one source at once. Swipe right to keep, left to archive, up to delete, with a 10-second undo on every action. A smart unsubscribe flow handles newsletters in one tap, falling back to an email request when no link exists. A full gamification layer — points, 55+ badges across five rarity tiers, daily streaks with shield protection, and levels from Rookie to Inbox God — keeps the cleanup loop rewarding. Everything runs on-device against the Gmail API, with progress persisted locally.
