Hi! I am Roy, your personal assistant.

At times, there are simply not enough hours in the day. This is the app that helps you in everyday life. Whether it’s to keep track of your to-dos, to find the best restaurants or to see all your calendars in one place. I am an artificial intelligence that helps to plan your daily life more efficiently, from to-do's to booking a restaurant, from calendars to events I have you covered.

Here’s how I can help you to be your most productive self:

** First smart to-do list **
- Automatically scheduled to-dos at the best possible time. I'll consider things like your schedule, work hours, holidays, the weather and more.
- Don't worry if you forget about a to-do. This sometimes happens. I'll make sure to reschedule it for you automatically.
- Tag your to-dos to get even more organized.
- Drag and drop your to-dos in the Eisenhower matrix and I will take care of the rest.
- One step to-do creation.

** Beautiful agenda and dark mode **
- Butleroy supports the native iOS dark mode feature and comes in a beautiful dark color scheme (if you want)
- Calendar marries to-do. It's 2019 and you can finally see your calendar events and to-dos in one place.
- Powerful filter options, so you only see the right things at the right time.
- Access to over 9.5 million calendars of sport teams, tv shows, moon phases, public holidays and more. From NFL to second league volleyball in Slovakia, we have them all.

** Powerful integrations **
- Combine your favourite calendars and other apps in one.
- Integrate Google Calendar/Tasks, Microsoft To-Do and Outlook to see your tasks next to your events.
- See your iOS Reminder so you have the best possible overview.
- Hook up Todoist to make use of the intelligent scheduling and to see your to-dos right in your calendar.
- Connect Trello "cards" so you can see everything that is going on today at a glance.
- Wunderlist To-dos
- Hubspot tasks

** Smart personal assistant **
- If you need an Uber or a Lyft to your next event or simply the directions, I have your back.
- Parking near your appointments is shown whenever you need it.
- Find the best restaurants in town from Google Places and Foursquare.
- Citymapper shows you the best way to get to your appointment.
- Message all event attendees at once with one click.
- Siri shortcuts allow you to automate tasks, schedule your to-dos even quicker or get an overview of your appointments and to-dos. All controlled with your voice and Siri.

What’s New

Version 1.2.0

You can now plan your day with ease. This update allows you to select all to-dos that you want to get done today and Roy plans them automatically.

You can also set a duration for Reminders now. They are saved into the notes of the reminder as well, so you can even see them in the original app.

Good app with great potential

I've been looking for an app to help manage my time for awhile. This app has almost everything I need: integration between to-dos and calendar, smart scheduling of to-dos, etc. There are a few minor bugs. I've sent feedback to the dev team, and they've been responsive, so I am optimistic they will continue refining it into a truly great app!

Great integrated view of calendar & to-dos!

So nice having everything together in one view and so easy to setup where it simply pulls in all the data you've already setup in your MacOS Calendar and Reminders apps. The "intelligence" is pretty cool too and I see a lot of potential there for future versions. Development team is very responsive and friendly when it comes to reporting issues or suggesting new features. Well done!

As others have noted, the user interface is not intuitive, but I was able to get over that and set it up. However, since set up, calendar events keep disappearing- when I quit and re-open they appear again, but inevitably disappear again. Reminders aren't working and without my calendar being correct and up-to-date the product is useless. I tried to contact their support via email to see if I had something incorrect with the set up, but never received a response (it has been 4 days, no word). So, back to using Todoist and Fantastical instead.

Developer Response ,

Hi JenFAZ, thank you very much for your feedback. We really appreciate if users take the time to leave a review. Disappearing events is cumbersome and I can understand that this is annoying. As this sounds like an individual issue we would have to investigate in that together. We contacted you via email today. At the moment we are getting a lot of requests and the whole Butleroy team only consists of four people, so we have somehow limited resources and can't reply to everyone immediately. Nonetheless, we take customer support very seriously and everyone gets a reply. We are happy to help and make the app work for you. Many thanks!
