Calendar Tools

Leanback is your personal AI assistant for managing engineering teams. It checks in with your team, reads every ticket and calendar, and delivers a clear action plan inside Slack, before your first coffee.

Most calendar apps assume you'll glance at them. Ahem! assumes you won't. On Mac and Windows, full-screen reminders interrupt deep focus, and one hotkey reveals your day. On iPhone, live countdowns, Lock Screen reminders and Dynamic Island nudges keep your next meeting in sight. Built for ADHD, time blindness and deep focus. Works with Google, Outlook and iCloud calendars. Available in 17 languages. Pay once per app, no subscription.

Most planners help you make a plan. Flowo helps when the plan stops matching the day. It builds your day from tasks, fixed events and limits like sleep and meals, then rebuilds what is left when something runs long, and shows what moved and why. Brain dump by typing or voice, habits that scale down in hard weeks, and a Pomodoro timer that starts from the plan. No account; planning data stays encrypted on your phone. Free on iPhone and Android, with an optional Pro plan.

Takweem is an AI-first calendar. Ask in plain language, or by voice, to find time, move meetings or protect focus. You see every change before it counts: requests that only touch your own time are applied at once with Undo, and anything involving other people waits for your approval. It adapts when plans change, holds a weekly focus goal, and offers team availability and booking links where AI picks the best time. Integrates with Google Calendar — Outlook coming soon.

A time blocking app for Mac that puts your tasks and calendar in one place. Drag a task onto your day and it becomes a block, and a countdown shows how long is left on it. Syncs both ways with Google, Outlook and Apple Calendar, and pulls in Apple Reminders. Save a good day as a template, or ask Claude to plan your week. Your data stays on your Macs and syncs through your own iCloud. No subscription, 7 days free no card required.

Calnio syncs Notion tasks and Apple Calendar both ways, real iCloud events with alerts, not a read-only webcal feed. Edit in either app, the other updates. Free, built by an indie dev and hosted on a Raspberry Pi at home.

Let the shape of your day tell the story. Reassign is a 24-hour circular planner for busy makers. Midnight up top, noon at the bottom. Drag to block time. Reshape it when plans fall apart. It speaks AI. Brain-dump or brainstorm into the command palette and watch AI rebuild your afternoon, live. It mirrors everything. Google Calendar, Outlook, Todoist, Linear, all in two-way sync. Plus focus mode and an energy curve from your sleep. One dial. Every source. Full control.

Donna lets you combine a sequence of meetings into a single booking link. Instead of sending different links for every call, one link chains all meetings together with conditions like setting time gaps between meetings or keeping the next meeting locked until the previous one is completed. It also includes built-in workflows to prioritize important meetings, fill cancellations, route meetings across teams, and more.

A native Mac app for planning your day. Press ⌥⌘ K over anything, or hold ⌥⌘L and just say it, and it lands on the right day. Your Google Calendar sits beside your tasks, reminders ring at their time, and it all works offline.

Stop wasting 3 days scheduling a 30 minute group meeting or starting over every time someone cancels. Like a real executive assistant, Toki will email attendees, negotiate a time that works for everyone, follow up if needed, and send out invites. Toki will also help protect your time, architect your schedule, remember your preferences, and help you prioritize your most important tasks and urgent deadlines. And instead of paying tens of thousands, it's now free.

Grimo AI turns one spoken or typed sentence into tasks, calendar events, and notes — no forms, no switching apps. Say the words and Grimo files it exactly where it belongs, dated and prioritized. Built for messy weeks: a calendar that shows overlaps at a glance, hands-free voice mode for when your hands are full, and one chat thread so nothing gets lost across five different apps. Free to start. iOS only.

Your week lives in a calendar, your to-dos in a list, your plans in a group chat. Work Life Panda puts them in one calm place — a real task manager and real calendar, together, starting with the life you already have. Every task and event has its own chat.

Outlook Google Calendar Sync for Mac keeps your Outlook events mirrored into Google Calendar without needing Microsoft admin approval. It runs locally on your Mac, supports multiple calendar sync jobs, avoids sending duplicate invites, and quietly keeps your schedule up to date in the background.

Chronock combines scheduling and cross-calendar sync in one workspace. It checks availability across connected Google and Outlook calendars, turns open time into a booking page, and syncs events between work, personal, and project calendars to prevent double bookings. Guests see only bookable times, while you can review every connected event in one Integrated Calendar. Start free with no credit card.

Compass is a simple, keyboard-first calendar that helps you manage your time. It's built around vim-style shortcuts that make scheduling feel like a fun game of Tetris. If you live at the keyboard and in your calendar, Compass will make your life easier. Although Compass is built around speed, sometimes the most productive thing to do is nothing. That's why we also have a "life" view, which shows your life as a grid of dots. This visual will help you filter out non-essentials.

Your services, prices, calendar, payments, and reminders — all in one beautiful page. Clients book in 30 seconds. You set it up in 10 minutes.
