KeepBy keeps your household's time-sensitive things in one place — food expiry dates and appliance warranties — and shares them with your family. • Food & warranties together: track best-before dates and warranty end dates side by side, color-coded by how soon they expire. • Shared with family: invite household members with a code (valid for 2 days). Everyone sees the same items, shopping list, and status. • Smart reminders: get notified before food expires (3 days & day-of) and before warranties end (30 & 7 days & day-of). • Straight to the shopping list: when something runs out, send it to the shared shopping list in a tap — buy it, and it's back in stock. • Receipts & photos: attach a photo of the item or its receipt. On-device receipt scanning reads dates and amounts for you — no data leaves your device. Pro unlocks unlimited tracked items and family sharing. Only one household member needs Pro — status is shared across the household. Sharing and syncing across devices require signing in with Apple.
