**When did you open that jar?**
Yesterday? Three days ago? Stop guessing.
OPEN helps you remember when you opened food and drinks, keep track of the dates you choose, and get a reminder when it’s time to check them. No complicated fridge inventory. No account. Just a simple way to remember.
**OPEN IT. SAVE THE DATE.**
Add a product, confirm its opening date, and you’re done. Want a reminder? Enter the number of days shown on the packaging or choose a specific date.
Only need to remember when you opened something? Save the opening date without setting a reminder.
**YOUR OPENED PRODUCTS, AT A GLANCE**
See what you’ve opened and how many days have passed. Products with upcoming dates, dates set for today, and dates that have passed are easy to find.
**SAVE YOUR REGULARS**
Keep frequently used products as favorites. The next time you open another carton, jar, or container, reuse its settings instead of entering everything again.
Have two containers of the same product open? Track them separately.
**REMINDERS WITHOUT THE CLUTTER**
Choose your preferred reminder time and receive notifications for the dates you set. When several products need attention, OPEN groups reminders to keep things simple.
Need another nudge? Ask to be reminded tomorrow without changing the original date.
**QUICK ACCESS FROM YOUR HOME SCREEN**
Use the widget to start a new opening entry from your favorites without navigating through the app.
**FINISHED? ONE TAP.**
Mark a product as finished and move it to your history. You can also record something as discarded, undo a mistake, or start a new container from a previous entry.

**YOUR RECORDS STAY UNDER YOUR CONTROL**
OPEN stores your records on your device. Export a backup when you want to keep a copy or move your data.
**A DATE REMINDER, NOT A FOOD SAFETY CHECK**
OPEN tracks the dates you enter. It does not determine whether food is safe to eat or automatically calculate safe storage periods. Always follow the product’s packaging and storage instructions.
Notification delivery may be delayed by your device’s settings.
Spend less time wondering when you opened it. Remember with OPEN.
