## What is Mayday?

Mayday is the next generation of scheduling software, that uses AI to personalize productivity. Combining an AI Assistant with a calendar and task manager, Mayday learns what’s important and ensures everyone spends time on what matters most.

This release currently supports Google Calendar, Google Meets, Microsoft Outlook, Microsoft Teams, and Zoom accounts. Additional integrations are coming soon.

— AI-based Scheduling  —

Mayday analyzes your calendar and scheduling patterns in order to determine when the ideal time for different types of events and tasks will be. Automatically find an ideal time for anything you need to schedule or re-schedule.

- AI that applies different scheduling hours for different types of events and tasks
- One-click reschedule to a new ideal time as priorities shift
- Assessment of your and your guests’ true availability based on multiple shared calendars and timezone constraints

— AI-scheduled Tasks  —

Block out time for the things that you need to do with Tasks for Mayday. With flexible tasks created in Mayday, your AI assistant can reschedule your tasks as priorities evolve:

- Create tasks with unique attributes across multiple different calendars
- Auto-rescheduled tasks find new ideal times automatically as soon as conflicts with other events or tasks arise
- Incomplete tasks from the previous day will automatically reschedule to a new time if left unfinished

— One Timeline —

Mayday brings all of your calendars - work, personal, shared - 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

— Scheduling Links —

With Mayday Scheduling Links, 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.

- Easily create custom single-use or reusable scheduling links that reflect your true availability
- Book meetings that match the structure of your ideal week, not whenever your calendar is empty
- Create event limits to ensure the same link isn’t used too often

— Smart Tag Automations —

Create automations for different types of events and tasks with Smart Tags and give your calendar more context. Use Smart Tags when creating events in order to quickly set defaults and organize common types of events.

- Create new events and tasks faster with Smart Tag based defaults that fill in your ideal parameters
- View the makeup of your week at a glance with Smart Tag colours
- Automatic event syncing rules so certain tagged events can be reflected in multiple calendars

— Protect time with Calendar Shield —

Calendar Shield ensures 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.

- 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

### 5/5 — DONT CLOSE

*2024-04-22*

Please don't discontinue your app, i use it everyday

### 5/5 — Sad to see a great app go

*2024-04-05*

This was such a great calendar app. I’m so sad to see it go. It was the perfect blend of simplicity and functionality. I loved being able to contribute ideas and reporting bugs I encountered. This really was an amazing app and I loved how they had it set up.

### 2/5 — Very nice UI but totally useless

*2024-03-25*

The team for this app clearly spent too much time making it look all nice and fluffy. It promises all the features we want but fails to do basic things like integrate with iCal. How does an app that only exists within the Mac user ecosystem not integrate with iCal!? The obvious issue for me appeared as I was excitingly starting to use the app and it started repeatedly crashing when I tried to add events. Not clear what's going on but the user experience is not smooth. Needs more work.

### 3/5 — Great idea!

*2024-02-28*

Using AI to map out the day,  help plan projects, etc. is a fantastic idea. Unfortunately like others have mentioned I couldn’t get my Microsoft 365 work calendar to sync so I couldn’t really go from there. Giving it a hopeful three stars that this will be fixed soon.

### 2/5 — Unfortunately fails at its most basic job

*2024-02-25*

I want to love it. The auto-tagging is useful, buffer time is great, condensed display of the same event in multiple calendars is fantastic, and copying events across calendars is well done. It’s got so much good stuff.

But. It doesn’t sync events from Google Calendar consistently. It just doesn’t. There have been *many* times now where a meeting just doesn’t show up in Mayday, even days after it’s added. I used both the iOS app and the macOS app. I don’t know if it’s because I just keep them open without restarting, but either way, not having your actual events visible in your calendar app is a table stakes failure that makes it categorically unfit for the job. I missed multiple meetings because of it until I realized what was happening.

There hasn’t been an update for 3 months, and that bug is too egregious to bear. I kept having to check Google Calendar to confirm what I was seeing in Mayday was real, until eventually I realized I was back to using it full time. A real shame.

### 3/5 — Great Potential

*2024-01-11*

This is a really innovative calendar app. The integration of tasks and automatic rescheduling of them is nice. The intelligent sync across multiple calendars is fantastic. Buffer time is really useful. Tag-based defaults for events also really useful.

Unfortunately, I can't use it as my primary calendar, because events just don't stay in sync with Google Calendar. I've turned up multiple times to meetings that had been moved or where folks had cancelled, and it wasn't reflected in Mayday. There is a manual sync button, but if I have to press it multiple times a day because I'm not confident that it's up to date, I might as well just use the original calendar.

I really, really hope they fix this because I love everything else about the product, and I'd love to use it and nothing else.

### 3/5 — Still Not For Me

*2023-11-07*

The app is designed well and I love how it works. There been iCloud support coming for a long time and it’s still not here, so I can’t view my full agenda. Without that, the AI and stuff isn’t helpful. Any developer that puts an app on Apple’s App Store should be ashamed for not including iCloud. That should be ready to go day one. I kept the app to check every so often but I give up, it’s just vaporware and this app seems like it’ll never be for me.

### 5/5 — Great Calendar App

*2023-10-16*

I live in my calendar and being able to book tasks and events that automatically shift based on what’s going on in the day is a game changer!

### 2/5 — I so wanted to use this

*2023-08-17*

Unfortunately, iCloud calendar isn’t supported (yet?) and you have to have admin rights to approve access to Exchange calendars…so I can’t hook up my work calendar OR my personal one. 

Bummer :(

### 3/5 — Nice start, but a little ways to go

*2023-04-05*

I've been searching for a killer calendar app for Mac for a while that balanced beautiful design with great functionality. So Mayday seems to be heading in the right direction to be that app. It's design is top notch with decent functionality. I understand the app is in beta, so it's completely understandable that there are still some issues to iron out. Once ironed out, I think Mayday could be the hidden gem of calendar apps. I'm looking forward to watching this app evolve.
