Read full description

Opelog is a simple open date log and product tracker for cosmetics, skincare, beauty items, and everyday essentials. Record when you opened an item, track how many days have passed, and set check dates or reminders for replacements. “When did I open this serum?” “How long have I been using this lotion?” “When did I last replace this toothbrush?” “Is it time to check this filter?” Opelog helps you remember those small everyday “when did I open it?” moments with photos, dates, reminders, and notes. You can record item photos, categories, open dates, check dates, reminders, and notes. Opelog makes it easy to see how many days have passed since opening an item and how many days remain until the next check. Finished items can be saved to your finished-item log. You can review the open date, finish date, and number of days used, making it easier to plan replacements, repurchases, and beauty empties records. You can also add notes such as “favorite,” “buy again,” or “do not repeat” to finished items. It is useful for skincare reviews, cosmetic empties, daily item replacement records, and repurchase planning. Opelog can be used without login, and your data is stored on your device.
