## What is Opened On?

One less opening date to remember.

Opened On records when you open or start using everyday items. Keep a photo, date and note for coffee, jam, detergent and more.

OPENING DATES AT A GLANCE
Save an item name, opening date, photo, category and note. The opening day is day zero; elapsed days update as the local calendar date changes. Photos are optional.

YOUR OWN CHECK-IN REMINDERS
Choose when you want to check an item. With permission, a local notification reminds you at that time. Up to 60 upcoming reminders are scheduled and refreshed when you open the app. Focus and other device settings may silence alerts. These are your chosen check-in dates, not predicted expiry dates.

FIND WHAT YOU OPENED
Filter by Food or Household and search names and notes. Edit your records whenever things change.

KEEP A FINISHED HISTORY
Move finished items to History and look back at how long you used them. Restore an item to the open list if you moved it by mistake.

PHOTO-INCLUSIVE BACKUP
Export records and photos as a JSON file and import it later. Import adds missing records without overwriting existing records with the same ID. Backups may contain personal information: store them somewhere safe.

TRY THE SAMPLE
Explore temporary sample items without affecting your personal records. Sample photos are AI-generated illustrations.

Free, with no ads, purchases or account required. Records and photos stay on your device.

The app does not assess expiry, quality or safety, or recommend how long food is safe to eat. Follow product labels and storage instructions. Export a backup before changing devices or deleting the app.
