Mottai: Expiry & Stock

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.
