Never forget an expiry date again. Drop That Due helps you track all your expiring items in one simple, offline place. Whether it’s food, medicine, cosmetics, documents, or appliances — add them once, and let the app remind you before they expire. Simple & Quick Entry Add items with just a few taps: name, category, expiry date, purchase date, quantity, notes, and custom reminder days. Choose from preset categories like Food, Electronics, Medicine, Cosmetics, Documents, or create your own. Smart Reminders – Even When App Is Closed Schedule local notifications so you never miss a due date. Set a default reminder time or adjust it per item. Notifications appear even if the app is not running – because iOS handles them reliably. Badge Count at a Glance See the number of expiring or soon‑to‑expire items right on your home screen icon. The badge updates automatically as you add, edit, or consume items. Calendar Integration With one tap, add any item to your system calendar as an all‑day event. The reminder will be set according to your preferred lead time. Perfect for important documents or long‑term warranties. Organize by Categories Filter your list by category to focus on what matters. Create, rename, or delete categories – fully customizable with emoji icons and colors. Consumable & Non‑consumable Items For food or supplies, mark items as consumable and reduce the quantity each time you use one. When quantity reaches zero, the item is automatically marked as done. For non‑consumables (like electronics), simply mark them as completed when no longer needed. Export Your Data Export all your items and categories to a CSV file. The file is saved to your device’s local storage. You own your data – always. Complete Offline & Private No account, no sync, no internet connection required. All your data stays on your iPhone.
