12+ Best Calendar & Appointment Scheduling Software

With the ever-increasing need to stay on top of daily tasks, calendar and appointment scheduling software have become invaluable tools. Today, there are a variety of calendar and appointment scheduling applications that can help you stay organized, save time, and increase productivity. 

From basic calendar applications to calendar APIs, technology has made it easier than ever to keep track of meetings, appointments, and deadlines. This article will review the best types of calendar and appointment scheduling software, the features they offer, and how to choose the best one for your needs.

Types of calendar and scheduling tools

Not all calendar scheduling software offers the same capabilities. Some are solely for scheduling and managing appointments, while others are APIs that connect to your users’ calendars and allow you to quickly build customizable scheduling workflows in your application.

Let’s take a look at the different types and features of scheduling software. 

Appointment scheduling 

Appointment scheduling tools include: 

  • A web-based application that allows users to access their calendar from any device or browser
  • A backend interface where administrators can view customer information, track attendance records, customize appointment types, apply services, and analyze customer behavior

Employee management

Employee management tools track employee schedules and hours worked, store employee data, and help with payroll processing. 

They help teams track projects, deadlines, and scheduling changes. Managers can also use these tools to plan team meetings, design onboarding schedules, and organize future vacation or sick days. 

Calendar APIs

A calendar API integrates your application with various calendars. Your development team can spend months to years building integrations from scratch, or they can significantly reduce this hassle and use a calendar API. You can reduce your time-to-market with out-of-the box,  intelligent scheduling features that simplify workflows and increase user productivity.

Benefits of using calendar scheduling apps

Calendar scheduling apps provide a range of benefits for both individuals and businesses, including:

Streamlined workflows

Calendar and scheduling applications create a central hub for organizing and managing appointments. They often integrate with other productivity tools, such as project management software, enabling easy collaboration between departments and users. 

They also eliminate potential scheduling conflicts, remove the back-and-forth of scheduling via emails, and reduce no-shows. 

Operational efficiencies

No matter what scheduling appointment software you use, these applications enable businesses to quickly and easily scale their scheduling efforts. For example, if you’re using employee scheduling software, you can quickly adjust staffing needs depending on customer demands and employee availability

Calendar APIs, in particular, are ideal for rapidly growing or changing companies since they can expand their scheduling capabilities without the extra cost of hardware and software. A calendar API vs. a simple scheduling application is ideal for those who need to integrate a scheduling solution into their app, but also need highly customizable functionality. 

Cost optimization

With improved productivity, efficient operations, and reduced development time, calendar and scheduling applications save businesses time and money. 

Instead of a team of developers spending one to two years (or more) creating their own platform, calendar APIs enable engineering teams to add scheduling capabilities into their applications in just a few sprints. These platforms also drastically reduce ongoing maintenance, bug resolution, and unanticipated customer requests that come with building these communication needs in-house

Scheduling apps can also provide intelligent insights that help businesses make data-informed decisions about budgeting for future projects or initiatives.

What to look for in scheduling software

When shopping for scheduling software, it’s important to consider several key factors. Some of the things you should look for in scheduling software include the following:


Good scheduling software should offer you a flexible workflow. It should enable you to 

  • Create different appointment types and lengths 
  • Customize interfaces and calendar templates native to your brand, voice, and style
  • Manage your workload seamlessly by integrating with other business tools 
  • Offer mobile access to run your operations on the go while away from the office

Calendar syncing

An effective calendar scheduling app allows users to sync with any calendar application they’re using. Once linked, any changes made to the user’s calendar through the app will be reflected in the other calendars and vice versa. This allows users to manage their schedules in a single place and ensures that their appointments are always up-to-date and accurate.

Easy integrations 

Calendar scheduling apps should provide simple and intuitive methods for connecting the app with other platforms. This should include: 

  • User-friendly interfaces with simple toggle switches or drop-down menus for enabling or disabling integrations
  • Onboarding and setup assistance like live chat support, email support, or in-app guidance and tutorials

API capabilities

API capabilities take calendar and scheduling software to another level. An API enables you to build a tailored, front-end scheduler unique to your brand and scheduling needs.

Nylas’s calendar API is a single point of integration to connect to your users’ calendars and quickly build customizable scheduling workflows in your application. It removes the complexity of implementation, allowing your developers to focus on product innovation rather than dealing with complex protocols.
