Our verdict on Simple Calendar
Simple Calendar is an open-source Android calendar app for individuals and families who want to organize personal and work schedules without requiring an internet connection. Its core planning tools cover daily, weekly, monthly, yearly, and event views, along with recurring events, custom reminders, notifications, themes, colors, and widgets. Holiday, birthday, and anniversary imports add useful personal-calendar coverage, while ICS import and export support makes calendar data easier to move between services.
The free offering provides the basic Android calendar experience, including calendar views and reminders, but contains ads and in-app purchases. Simple Calendar Pro adds an ad-free experience, offline calendar access, CalDAV synchronization, and customizable calendars and reminders. The product supports two-way synchronization with Google Calendar, Outlook, and CalDAV services, with listed ecosystem connections including Nextcloud and Exchange. That combination suits users who want local calendar access while keeping events connected across supported services.
Customization and offline operation are the clearest reasons to choose Simple Calendar. It offers multiple views, recurring events, configurable reminders, widgets, themes, colors, notifications, and event sharing through social media and email. The narrower fit is equally clear: it is an Android-only option, and its sharing features do not provide verified scheduling links or broader collaborative scheduling tools. Choose it for offline personal or family calendar management with flexible synchronization; consider another calendar app if cross-platform access or link-based scheduling is central to your workflow.
