Keeper: Relationship Tracker is a lifestyle application designed to help users commemorate their relationship milestones. The app allows users to track three significant dates: when they met, when they started dating, and when they got married. By enabling push notifications, users receive reminders for anniversaries and other notable milestones, ensuring that special dates are never overlooked.

Additionally, Keeper offers customization options, allowing users to personalize their relationship counter with a picture. For those interested in enhanced functionality, an in-app purchase enables a widget for the home screen or a complication for Apple Watch, providing easy access to relationship updates and reminders directly from their devices.
