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.

Doodle

Doodle is a scheduling tool that removes the back-and-forth of finding a meeting time by letting organizers create group polls, sign-up sheets, and 1:1 booking pages that invitees fill in with their availability. It connects to existing calendars so proposed times automatically avoid conflicts, and supports Zoom, Teams, and Webex integration for turning a scheduled slot straight into a video call. Paid tiers add unlimited polls and booking pages, custom branding, Stripe payment collection on bookings, and team-level features like an admin console, activity reports, and workload-aware smart scheduling that protects focus time. The Enterprise tier adds SSO, MFA, and a dedicated success manager for larger organizations, and Doodle holds 4.8/5 ratings on both G2 and Capterra.

Motion

Motion is an AI-driven productivity platform that merges task management, calendar scheduling, project planning, and meeting notes into a single workspace. Its AI Task Planner automatically prioritizes and schedules tasks around deadlines and dependencies, while the AI Calendar Assistant rearranges a user's day as new commitments appear. The platform also includes an AI Project Manager that can generate a full project plan from a text description, an AI meeting notetaker that records and summarizes calls into action items, and workflow automation that turns standard operating procedures into repeatable processes. It combines multiple calendars like Google and Outlook into a single unified view.

Morgen

Morgen consolidates multiple calendars (Google, Outlook, Apple, Fastmail) into one view and connects to task tools like Notion, ClickUp, Linear, and Todoist so tasks can be time-blocked directly onto the calendar. Its AI Planner suggests scheduling, resolves conflicts, and automates buffer and travel time around meetings.

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.

Vimcal

Vimcal is a calendar app designed for speed, aimed at busy professionals who manage a high volume of meetings.
