About this app

This app sends you a push notification of your shopping list when you arrive at a nearby store.

--
■ How to Use

1. Add items you want to buy to your list.
2. Register stores on the map (OpenStreetMap) (e.g., your favorite supermarket, drugstore).
3. Just carry the app with you. You'll receive a notification when you're near a registered store.

You don't need to have the app open. It works even if the screen is off or the app is closed.

■ AI automatically determines the store based on the item name.

For example, "milk" will result in a supermarket, "charger" in an electronics store, and "bandage" in a pharmacy. The AI ​​automatically categorizes the store where you can buy the item based on the item name.

Supported categories: 10 types: supermarket, convenience store, pharmacy, electronics, clothing, food and beverage, 100-yen store, home center, etc. You can manually change the category if it's incorrect.

By assigning categories, you'll receive supermarket notifications when you're near a supermarket, and pharmacy notifications when you're near a drugstore.

■ About Background Location Information

The "Notify Me When I'm Nearby" feature won't work unless the app can track your device's location even when it's closed. Therefore, we request background location access.

We use the OS's geofencing function to detect and notify you when you enter the vicinity of a registered store. We do not store location history on a server or analyze movement patterns.

Allowing background location information is optional. Even without permission, notifications while the app is open and manual store searches will still work.

■ No Login Required

Neither an email address nor a password is required. An anonymous, device-based account is automatically generated upon first launch.

When changing devices, data will be transferred by entering the transfer code issued within the app into the new device.

--

■ Shareable with Family and Households

The group sharing function allows multiple people to update and view the same shopping list. When one person checks an item, it is reflected for all sharing members.

--

■ Works Offline

This app prioritizes local device data, using an offline-first design. Viewing, adding items to, and checking items in your list will work even in areas with unstable network connectivity. It will synchronize with the cloud once the connection is restored.

■ Permissions

• Location (Precise/Background): For detecting and notifying you of store proximity
