Google Calendar (Android, iOS, Web)

Much of Google Calendar‘s popularity comes from the fact that you can create multiple calendars in one place using a Google account, and then port those entries to almost any other online calendar. Google Calendar also works with nearly everything else on the market. You can connect your Google Calendar not only to other calendar apps, but also to business apps and services that have calendars as part of their features, such as Trello and Asana.

Color-coding for individual calendars makes it easy to see which area of your life an event applies to. You can also show or hide calendars, so you can focus on specific types of events. As you would expect from the company that started as a search tool, Google Calendar offers excellent search capabilities. It also integrates with Google Workplace (formerly G Suite) apps, letting you create a calendar event from Gmail, for example. 

When used across an entire organization, Google Calendar gives you the ability to check your coworkers’ schedules alongside your own. Inviting others to your calendar is a cinch too. You can choose between sharing an entire calendar or just using the invite option to add people to an event.

Although there’s no desktop app, Google Calendar’s web app and mobile apps for Android and iOS are enough to keep schedules straight. If you want a more enticing user interface or more robust features, you can always connect Google Calendar to virtually any other app on this list.

We make scheduling easier by eliminating the back-and-forth emails usually involved in finding a meeting time. Just enter your availability and Calendly creates a link that will take people to your schedule.

You can integrate Calendly with many of the tools your team already uses, from Slack to Zoom. If you integrate with Google, Outlook or another supported calendar, Calendly will automatically add your events to that calendar. (Android, iOS, Web) screenshot
