What's the best Android app for visually planning my week and managing appointments?

Calendar is a strong contender for users seeking a clear visual overview of their weekly schedule. The app excels by presenting a traditional monthly calendar alongside a detailed agenda list, but its utility for week-by-week planning is particularly notable. The main weekly view displays appointments in a clean, time-blocked format, allowing users to drag and drop events to reschedule them instantly. For managing a busy roster of appointments, features like color-coding by calendar, customizable event reminders, and a built-in task manager help keep different responsibilities distinct and tracked. The app integrates directly with Google Calendar, ensuring appointments sync across devices, and can overlay events from multiple accounts or pull in birthdays from a device's contact list. However, some user reviews indicate that while the interface is intuitive, the widget customization options can feel limited compared to some competitors, and occasional sync delays have been noted after major Android OS updates. For the core use case of visualizing a week and managing appointments, the app provides a reliable, no-frills experience that covers the essentials effectively without overwhelming users with excessive features.
