Time is your most valuable asset, but it's too easily lost, stolen, or misspent. Mayday aims to fix that.

Mayday is a helpful calendar that gives you control of your schedule and helps you spend time in more meaningful ways. Mayday develops a comprehensive understanding of demands on your schedule and helps you to prioritize what matters most to you.

This release currently supports Google Calendar and Zoom accounts. Additional integrations are coming soon.

— One Timeline —

Break down the silos between your work life and your personal life. Mayday brings all of your calendars into one place to create a unified timeline for you. You get a complete picture of the demands on your time and help those you work with to understand when you're available.

- Privacy-first event duplication across calendars
- Unify duplicate events in your timeline
- Mark non-critical events as "FYI" to minimize their impact on your timeline

— Calendar Shield —

Calendar Shield optimizes the structure of your day so that you have plenty of time to do your work, during work. If a particular day starts to fill with too many meetings, Mayday automatically blocks the remaining time before you can get overloaded and at risk of burning out.

- Protect time across multiple calendars so your availability is always made clear to others
- Settings to adjust for more or less meetings depending on your role
- Customizable event descriptions

— Notifications —

Mayday analyzes your calendar for potential issues that need your attention, and brings them to your attention before they blow up your day. For example:

- Double-booked two meetings at the same time?
- Upcoming meeting without a location?
- Invitation to a meeting that you haven't yet accepted?
- Is an upcoming week unusually busy?

— Quick Meet —

Scheduling time to meet should be based on priorities, not by playing calendar Tetris. With Quick Meet, invite others to meetings based on flexible parameters that align with your priorities and let Mayday do the heavy lifting to find the best time to meet for everyone.

- Quickly send disposable scheduling links that reflect your availability
- Book meetings that match the structure of your ideal week, not whenever your calendar is empty
- Copy and customize your availability to suit the situation

— Your Day at a Glance —

With global shortcuts, Mayday lives in your Mac's menu bar and can provide a heads up overview of what coming up next without needing your full calendar.

- Menubar access gives you an overview of your schedule and how much time remains in your current meeting
- Join your next meeting link with one-click from wherever you are

What’s New

Version 3.1.0

New features:
- Ideal time suggestions between Mayday users. You can now find the ideal time for a meeting when creating an event in Mayday with other Mayday users. Mayday assesses everyone’s True Availability and indicates which times work best for everyone. Invite your team using the icon in the bottom left corner of the app and start scheduling your meetings at the ideal times for everyone.

General improvements:
- Recurring event performance. Updates to recurring event calculations now render your recurring events instantly on the timeline as they are being created so you can see the impact on your schedule at a glance.
- Attendee lookup improvements. Changes to significantly increase the speed of past attendee lookups and to highlight potential matches as you type.
- Location lookup improvements. Changes to location lookup logic so that location names will better parse and display alongside address information.
- Keyboard logic improvements. Added new keyboard logic when creating events to support the understanding of more date and time inputs.
- No connection indicator improvements. Updated the no connection indicator to better inform you when your internet connection has failed and your calendar is offline.

Bug fixes:
- External display interactions. Fixed an issue where certain clicking interactions weren’t registering for some users using external monitors on their Mac.
- Dragging events during editing. Fixed an issue where event tiles could be dragged to reschedule while being edited but new time wasn’t updating in event edit side panel.
- FYI calendars writing non-FYI events. Fixed an issue where calendars set to display in FYI state were writing new events as regular non-FYI events.
- Individual event FYI toggles reverting. Fixed an issue where individual events from FYI calendars could not be successfully toggled into a different FYI state.
- Issues with syncing copies of recurring events across calendars. Fixed an issue where recurring events that were synced to multiple calendars weren’t always writing copied “Busy” blocks for all events in the recurrence.
- Event scheduled notifications. Fixed an issue where notifications weren’t being received after a guest picks a time for a meeting from a Scheduling Link.
- Scheduling Links not capturing phone number or location settings. Fixed an issue where new Scheduling Links weren’t capturing user defined phone number or location settings for the link at creation.
- Editing Scheduling Links. Fixed an issue that prevented users from editing Scheduling Links to change the fixed date range options.
- Buffer time fixes. Multiple fixes to improve option selection when editing events to add/remove buffer time.
- Multi-day events showing date as “Today”. Fixed an edge case where multi-day events incorrectly display the event dates on the event tile.
- Attendee availability. Fixed an issue where some attendee availability options weren’t displaying correctly when editing events.

Hoping for access soon!

Hello! I've never actually written a review for an app before but this one just seems like a must have. I have had issues with Google Calendar and just never felt like it was right for me so I switched to bullet jounraling but I would forget about deadlines in case I ever forgot to bring it with me. I'm hoping that Mayday is it, and from the looks of it will likely be something that I will invest in getting if a pro version were to come out. I would love to start right away and get access to the app ASAP if possible since I am busiest right now. If there is someone I can email to let them know which email I used to sign up, that would be great. Thanks!

Great app .. read the comments

This is a fantastic calendar app, however you need an invite to use it. If you read the low reviews they are all complaining about not being able to use the app, and not because the app is bad.

Do your self a favor, go to the website and request access.


not available yet

WHen the software becomes available I will update this review, if I have not found one that meets my needs. Disappointed in app store that it has an app on here that is not available.
