BusyCal

BusyCal is a calendar application for Mac and iOS that extends the built-in Calendar app with features like Smart Filters, Calendar Sets, natural-language event entry, and travel-time calculations. It integrates with the Reminders app for task management and adds extras like weather, moon phases, and a menu bar heat-map view.

Calendly

Calendly is a scheduling tool that helps manage meetings and appointments. It allows users to share their availability with others, eliminating the need for back-and-forth emails or phone calls to schedule a meeting.

SavvyCal

SavvyCal is a scheduling tool that generates booking links, allowing invitees to overlay their own calendar against the host's availability. This reduces the back-and-forth of finding meeting times, making it easier to schedule meetings. With SavvyCal, users can share their availability and let others choose a time that works for them, streamlining the meeting scheduling process.

Reclaim.ai

Reclaim.ai is an AI scheduling layer that sits on top of Google or Outlook calendars. It automatically finds time for tasks, recurring habits, and focus blocks, then reshuffles them as meetings get added or moved, so your calendar stays realistic instead of just aspirational. Beyond individual scheduling, Reclaim offers Smart Meetings that find optimal times across every attendee's calendar, scheduling links for sharing availability, buffer time between back-to-back meetings, and workforce analytics that show teams where their time actually goes. It syncs multiple calendars together to avoid double-booking across work and personal accounts.

Fantastical

Fantastical, made by Flexibits, is a calendar and task app for Apple platforms and Windows that merges Google Calendar, Microsoft 365, Exchange, iCloud, Todoist, and CalDAV accounts into one unified view. Events can be created by typing plain-language phrases like 'Meeting with Sarah at 1pm tomorrow,' and the app automatically detects and adds video-call links from Zoom, Teams, Google Meet, and Webex. Beyond personal scheduling, Fantastical includes scheduling tools such as Openings for sharing availability and Proposals for coordinating meeting times with others, plus day/week/month/quarter/year views and customizable widgets. A free tier covers basic calendar use, while Fantastical Premium unlocks advanced scheduling features for individuals, families, and teams.
