Mijn kalender (My Calendar Period Tracker)

Mijn kalender (often localized from My Calendar) is a popular period tracking mobile application pre-installed or frequently used on Samsung mobile devices, particularly in the Dutch-speaking market. The app provides users with tools to track menstrual cycles, ovulation, and general reproductive health through a simple, user-friendly interface characterized by its red flower icon.

The application is developed and managed by Samsung Electronics, the South Korean multinational electronics giant. As a digital product, while the software code is developed primarily in South Korea, it is distributed globally through the Galaxy Store and Google Play Store. The brand and software remain under the ultimate ownership of Samsung, which continues to integrate these health-tracking features into its broader 'Samsung Health' ecosystem for global users.
