Local by default
SwiftData keeps the inventory available offline. Apple Vision reads expiration dates on the device, and captured OCR images are not retained.
iOS application in development
Emergency supplies, kept ready.
SurvivalSync helps households remember what they have, where it is stored, and when it expires—without requiring a paid service or uploading package photos for recognition.
A lightweight readiness companion
Find stored supplies
Save a shelf or box photo, storage-location history, and the matching AirTag name shown in Apple's Find My app.
Prepare together
Invite family members to a private, read/write CloudKit share while keeping local changes usable when the network is unavailable.
Free product lookup
Barcode lookup checks an offline cache, SurvivalSync's community records, Rakuten services for Japanese JAN codes, and Open Facts community databases.
Expiration reminders
Every dated item gets an offline D-day countdown. Optional EventKit integration adds an expiration event with future alerts 30, 7, and 1 day before the date.
Conservative coverage
Readiness rings and a local estimate show how many full days measured water and food energy can support the household, using the limiting resource and rounding down.
