Features of a Calendar App: Mandatory & Additional

What features should a successful plan calendar app have? For some people, organizing their time is important. Someone is looking for a business calendar app to collect online meetings and conferences. If a person is looking for a platform to perform many tasks, then one can only  do with such functions: synchronization, embedding, team use, mobile access, import, and export.

Calendar apps feature reminders, recurring events, and user-friendly search functionalities, significantly limiting administrative overhead and freeing up invaluable time for other tasks. Let’s look at the top six key features of a calendar app. Advanced search and filtering capabilities are important for users to quickly find specific events in a busy calendar.

Features are crucial when considering how to build a calendar app. The essential features are synchronization and event scheduling. The calendar design is also essential to meet user needs.

Event Scheduling

For professionals working remotely, the function of scheduling events in a calendar app is vital. This is useful for a multi-party meeting that can be accessed online, no matter where they are. Using your own calendar app, alongside meeting scheduling, you can also manage the allocation of resources, such as meeting rooms, equipment, and personnel.

The topic of a “smart calendar app” is also relevant, where you can track each participant’s employment. Imagine how convenient it is. You do not have to arrange a personal meeting, plunging yourself into a nightmare. You assign it with one click, adjusting to the free time of your colleagues, which helps avoid scheduling conflicts. Therefore, the event scheduling feature is the backbone of every business calendar app when it is developed. It should also support recurring events, a core calendar feature.

Sharing

Personalize your plans and tell only certain people when you’re busy with embed and event sharing in your calendar app. This feature is similar to the personal secretary you have on your smartphone. You can create a calendar for your team. You create your own calendar schedule in the calendar app and use filters to assign who can see it. They can also create a calendar for their own use and enter completed, current, and future planned things in their work. Build a calendar app with shared calendars to help track progress and leave comments for each event.

For privacy, you may want to generate a private calendar link. You may also want to offer event sharing for easy collaboration tools and managing event invitations. Implementing color coding can help organize events in your calendar.

Synchronization with other platforms

It is possible to update your schedules from several calendar apps, such as Google Calendar, Microsoft Outlook, or other calendars, in one place with the synchronization function across multiple devices. Making a calendar app with such a feature improves efficiency for those who manage multiple organizations, and it is essential to control critical events, especially across different time zones. Centralized management reduces the time to switch from platform to platform. Calendar integration is a must-have for a modern calendar app. This feature can connect your calendar across other apps.

Teamwork Calendar App

For small business owners with subordinate staff, it is important to control the team’s activities  and assign tasks. The team calendar app is the appointment of actions in one place through a single interface, offering shared calendars. Collaboration tools in calendar apps, such as shared calendars, are essential for coordinating plans among teams or families. Such management helps to coordinate employees and increase the productivity of the company. You can group each department this way within your calendar app. For example, the content department can negotiate and suggest the best time to post on social media, perhaps for weekly meetings.

Making a calendar app with this feature keeps everyone on the same page with team scheduling. This makes your calendar app a powerful set of productivity tools. With an app, you can invite more users to join events. A calander with Acuity scheduling improves team collaboration.

Import and Export

Let’s say you travel to work by public transport, which follows a certain schedule. There are in-app calendar applications that inform users about the movement of routes and publish actual bus arrival hours. You can import the suggested schedule into your personal calendar app. 

The import and export function allows you to save everything that interests you to your calendar app from the Internet. You can also upload individual audio, video, or image files with the ability to share them with other users of your calendar app. This calendar app functionality is expected by user needs.
