Best Calendar Software

Doodle is a Switzerland based scheduling tool best known for its group polls, where an organizer proposes several time slots and invitees vote on which ones work, removing the need for long email threads to settle on a meeting time. Alongside polls, Doodle offers 1:1 booking pages, sign up sheets, and calendar syncing with Google Calendar, Outlook, and iCloud so that busy times are automatically blocked.

The core product is free, covering group polls and a single booking page. Paid Professional and Team plans remove ads and add features such as custom branding, reminders, unlimited booking pages, and integrations with Microsoft Teams and Webex, while a custom priced Enterprise plan adds admin controls and activity reporting for larger organizations. Doodle is aimed mainly at individuals, small teams, and businesses that need quick, low friction meeting coordination rather than full appointment management.

Calendly is a cloud based scheduling platform that lets individuals and teams share a booking link so others can pick a meeting time without back and forth emails. It connects to Google Calendar, Outlook, Office 365 and iCloud, checks real time availability across up to six calendars, and automatically creates video conferencing links for Zoom, Google Meet or Microsoft Teams. Users define custom event types, buffers, and daily meeting limits.

Beyond one to one meetings, Calendly supports collective scheduling for co hosted sessions, round robin distribution for sales and recruiting teams, and routing forms that direct visitors to the right person. It integrates with Salesforce, HubSpot, Slack and Zapier, and offers an API for custom workflows. Plans range from a free tier to enterprise level security controls.

Google Calendar is Google's web based calendar and scheduling application, available free to anyone with a Google account and included in every Google Workspace subscription. It lets people create events, set reminders, and view multiple calendars side by side across web, iOS, and Android. Built in tools such as Find a Time, working hours, and out of office status help teams book meetings without back and forth emails, while automatic sync pulls in flights, hotel bookings, and restaurant reservations straight from Gmail.

For businesses, Calendar is bundled into every Google Workspace plan, from Business Starter through Enterprise, adding shared meeting rooms, booking pages, appointment scheduling with Stripe payments, and admin controls. It integrates natively with Gmail, Google Meet, and Drive, and connects to third party tools such as Zoom, Slack, and Microsoft Outlook through its public API. Because it is free for personal use and already familiar to most users, it remains one of the most widely adopted calendar tools worldwide.
