What makes a great calendar app?

Several key features make a calendar app stand out, including the ability to manage multiple calendars, integrate with apps or websites, and allow users to view and edit events easily. 

Let’s take a closer look at other features to look for when choosing the best calendar app for you.

Easy implementation 

A great calendar app allows easy implementation by providing a simple and intuitive user interface. It should also offer several ways to view a schedule, such as daily, weekly, or monthly views, and the ability to view multiple calendars in one place. 

Advanced calendar apps should seamlessly integrate with tools like email, contacts, and task lists to streamline your complete workflow.

The best calendar apps will provide a flexible and adaptable workflow that allows customers to manage and organize their schedules effectively. The app should enable end users to create different types of appointments and events, such as work-related tasks, personal appointments, or team meetings. 

Some tools also allow the customization of calendar templates to align with your brand. This can include options for selecting colors, fonts, and branding elements, as well as customizing the calendar layout and view. 

Calendar syncing 

Calendar apps should allow users to sync their calendars from other service providers, such as Google Calendar and Microsoft Outlook. Also, with the ability to link multiple calendars, users should be able to manage their events in a single, convenient location. 

They should also offer a two-way sync feature that allows any changes made through the app to reflect in the other linked calendars instantly. This feature helps reduce scheduling conflicts and ensures the user’s schedule remains accurate and current. 

API & integration capabilities

To ensure seamless integration, comprehensive calendar apps should provide clear and concise documentation, including step-by-step instructions so users can connect their calendars and set up integrations with other tools.  

Some calendar apps will also offer API access, which allows developers to create custom integrations that automate tasks and streamline processes.
