About
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.

What's New in Mottai
1.13.1
October 26, 2026
Scanning a barcode to check stock now searches your history too. If an item is no longer in stock, it shows up under "Bought before" — tap it and use "Add back to list" to quickly add a batch, no need to start from scratch. In item details, the newest batch now appears at the top, so there's no more scrolling to the bottom, and batches that are used up or handled no longer show expiry or expired labels for a cleaner view.
