Opelog Help & Support
Last Updated: May 5, 2026
Opelog is a simple opened-date logging app that lets you record the “opened date” of cosmetics, skincare products, daily necessities, and other items with photos.
To help you remember “When did I open this?”, you can manage the opened date, check estimate, notes, finished status, and other information for each item.
1. Adding an Item
You can register a new item from the add button inside the App.
The main information you can register includes:
- Photo
- Item name
- Category
- Opened date
- Check estimate
- Notes
Photos can be taken with the camera or selected from the photo library.
2. Recording the Opened Date
Once an item is registered, you can check how many days have passed since it was opened.
For example, the App can be used to manage items whose opened dates are easy to forget, such as lotions, serums, toothbrushes, filters, seasonings, pet supplies, and daily necessities.
3. About Check Estimates
By setting a check estimate, it becomes easier to see how many days remain until you should check an item, or whether the check date has already passed.
The check estimate does not guarantee a product’s expiration date or safety.
Please check the product label or manufacturer guidance to determine whether the item can actually be used.
4. Notifications
If notifications are allowed, you can receive reminders based on check estimates.
If notifications do not arrive, please check the following:
- Whether notifications for Opelog are allowed in your device settings
- Whether notifications are set within the App
- Whether Focus Mode or Do Not Disturb is enabled
- Whether there are any issues with the device power or network connection
5. Finished Log
Items that have been used up can be saved as a Finished Log.
In the Finished Log, you can look back on the opened date, finished date, number of days used, and other information.
This can help you decide when to replace an item or whether to buy it again.
6. Premium
Opelog may provide Premium features.
Premium may include features such as:
- Expanded item registration limit
- Ad removal
- Expanded archive features
- Theme changes
- Multiple photo registration
Premium features may change in the future.
Please check the latest details displayed within the App.
7. Data Storage
Opelog’s recorded data is generally stored on the device.
If the App is deleted, the saved data may also be deleted.
If you have important records, please check your device or operating system backup settings.
