With Check Day, you can: - Create recurring routines with a daily target count - Check in quickly from the app - View your progress for the current cycle at a glance - Edit or delete past check records - Set daily reset times for each routine - Receive reminders throughout the day - Use the home screen widget for faster access Check Day is designed to feel lightweight, clear, and fast, so you can keep up with your routines without unnecessary complexity.
