Never waste expiring items

Only for iPhone

Free · In‑App Purchases

iPhone

Log how much is left with a "remaining amount" slider on in-use items. Restock straight from history, and get notified when someone adds to the shared shopping list. Mottai tracks when things expire and how much you have left. ■ Scan to log in seconds (free) Scan a barcode to fill in the name, then add expiry, quantity, place and source. The camera can also read name and expiry — on-device. ■ Scan to check stock (free) Scan in the store to see how many you have across items and shared groups — never double-buy. No match? Add it, from Control Center or Lock Screen too. ■ Shopping list (free) Keep a list solo or shared. Add by hand, from low-stock suggestions, or tap "Restock" on any item. Entries show brand, size, barcode and photo and clear themselves once restocked. ■ Reminders before it expires Multi-stage reminders (same day, 3 or 7 days before…) at times you set, with per-category defaults. The "Expiring soon" section collapses with an adjustable day threshold and an "In use / Unopened" tag. Swipe to "Handle" a batch; search covers brand and notes. ■ Running-low reminders (Full Version) Mottai estimates how long each item lasts and nudges you before it runs out, shared members too. ■ Track items unit by unit (batches) Buy the same item in separate lots with different dates — each tracked and priced on its own. Switch on a gauge for an in-use unit to log roughly how much is left with a slider. ■ Review tab: history & stats (free) A "Review" tab unites history and stats: a timeline of what you used or discarded, plus overviews, categories and expiry views. Re-add or restock finished items from history in one tap. ■ Rate what you buy (free) Rate items 1–5 stars when you finish them to remember what's worth rebuying, stored on your device. ■ Spending insights (Full Version) Add price and capacity to see inventory value, monthly spend and a "Consumption by category" ranking. ■ Custom categories & widgets (Full Version) Two-level categories with custom icons and colors; personal categories can be imported from a shared space. Expiry and inventory widgets (Home and Lock Screen) switch spaces and page for more. A new "To Restock" widget lists what to buy and taps into Shopping. ■ Wallet Keep your Taiwan e-invoice carrier and loyalty cards here: swipe, tap to enlarge, scan to add. Carrier widget free; card widget Full Version. ■ Family Sharing with real-time alerts (Cloud plan) Subscribe to the Cloud plan to share one inventory — invited family join free. Everyone gets a real-time alert (with a nickname) when an item changes. Adding to the shared shopping list alerts everyone too; tap to open that group's list. ■ Dark Mode Light, Dark, or System. Plans • Free: up to 20 items, with scanning, stock check, shopping list, ratings, review and expiry reminders. • Full Version (one-time): unlimited items, running-low reminders, spending insights, custom categories, expiry + card widgets. • Cloud plan (subscription, free first month): all of Full Version plus Family Sharing — owner subscribes, family free. Privacy: item records sync in your own iCloud. Scan contributions are anonymous product facts only, never personal records. Family Sharing alerts go via Firebase (push token + nickname only). Crashlytics collects crash diagnostics and Firebase Analytics anonymous usage stats — not linked to you, no ads or tracking. ——— Subscription details Mottai Cloud (Family Sharing) • Price: NT$60 / month (approx.

  • This app hasn’t received enough ratings or reviews to display an overview.

Halfway through a bottle and want to remember how much is left? Any in-use unit can now switch on "remaining amount" — drag a slider to log roughly how much is left. It's great for shampoo, detergent and other slow-burn items, works for personal and shared items, and stays out of the way on items you don't turn it on for. Consumption history details now have "Restock": add a finished item to your to-buy list in one tap, even if the original item has been deleted. When someone adds to a shared shopping list, other members get a notification, and tapping it jumps straight to that group's shopping list. Also: a "running low" tag on item details, clearer rating stars in Dark Mode, custom reminder days you can type in directly, and capacity now defaults to g when adding items.
