Stockpile Gap Checker
Household supplies and expiry
Free · In‑App Purchases
See what is missing from your household's emergency supplies. Choose your household size and a target of 3 to 7 days, then enter the amounts of drinking water, meals and portable toilet supplies you have. The app shows suggested quantities and shortages.
Core features
- Update inventory by category, without registering individual products
- View missing categories and quantities in a shopping list
- Save purchased checkmarks; update stock quantities separately in Inventory
- Set an optional expiry month for each category and schedule local reminders
- No app account required. Household settings and inventory are stored on your device, and core features work offline
Free version and one-time Pro purchase
The free version includes one profile, shortage calculations, a shopping list and basic reminders. Banner ads appear at the bottom of Overview and Shopping.
Pro removes ads and unlocks up to three profiles, CSV export and reminders one month before expiry. It is a one-time purchase, not a subscription. Check the store purchase screen for pricing. Restore purchases with the purchasing account in the same store. Purchases are not shared between iOS and Android.
Choose Japanese, English, Simplified or Traditional Chinese, Spanish, Brazilian Portuguese, French or German in Settings.
Important information
Suggested quantities are based on Japanese public guidance in every language. Changing the language does not switch to another country's standards. This is not an official government app, an emergency alert service or an evacuation guide, and it does not guarantee safety. Adjust your supplies to your household's needs and local guidance.
Basic reminders are scheduled for 9 AM on the first day of the expiry month. Pro can also schedule a reminder one month earlier. OS permission is required, and delivery depends on device settings and conditions. Reminders apply only to the currently selected profile.
There is no cloud sync or automatic backup provided by the app. Purchases, restoration and ad delivery require internet access. External services are used for ad delivery and purchase processing. Usage analytics through Firebase Analytics is disabled. External services may process advertising, purchase and diagnostic information. Deleting device data does not delete data held by these services. See Privacy Policy and Support in Settings for privacy and deletion information.
