Currently we cannot sync UK Bank Holiday Dates into One Calendar on an iPhone from the iCloud calendar

Currently, you can add an address to an appointment, but if you need directions you must copy and paste the address into your maps app. It doesn’t even come up as a suggestion in maps like it would if entered in the Apple calendar or even searched in Yelp. This makes One Calendar feel a bit clunky and behind the connectivity curve. 

I know, that you can not change the app icon itself, but other calendar apps show the current date by using the app icon notification. I don't think, that you use it for other messages, so it would be very helpful, if the notification at the app icon can show the current day of the month as number (1-31).

Beside this, I love this app, thanks.

Monthly widget is nice but needs capability to be full screen and smaller font so more events can be easily seen

1. The option to add/open attachments in calendar entries
2. The ability to create and edit recurring/repeat appointments 
3. Apple Watch integration

Thanks, Neil

it would be great, if there was an possibility to define alarms per account. e.g.: disable alarms per account even if there are alarms within the appointments

Add a new feature to show other calendar in one calendar app such like lunar calendar, which has been became built in calendar in Apple calendar and Google calendar

Please add the ability to add and check odd tasks!

Could you please add the possibility to minimize the area for full day events or set it to a maximum size for this area and make it scrollable. We have that much full day events, that it take more than the half of the screen.

It's good to run the program, but I want you to add a widget function that you can see directly on your desktop to Windows 10 like mobile

I was wondering if it could be a good idea to add a facility where you could remove the greyed out days of the following month being shown on the current month

OneCalendar is s great app. Is there a way to have the icon show a badge with the date? Thanks!

Display or sync reminders of iOS devices like Fantastical does. it will save using Calendar and Reminders separately, and also boost the market of one calendar. 

Draw backs-

Also a very few updates has been available. would be nice if it has updates every 8 to 10 months so that it is current to the current needs.   the syncing time from my different calendars into one calendar is approximately 10-15 seconds. 

Would like to be able to add multiple reminders instead of just one

For people who have a busy day, a strikethrough feature that you could mark off tasks, appointments, or meetings would be beneficial to keep track of your day even more.

It would be really nice to be able import calendars instead of having to fork over account names and passwords. There are specific calendars from each service that I want to track with this app but I am unable to simply import an .ics or .olm file. Being a third-party app, this makes me leery about security.

Currently in month view, the date is red and in slightly bigger font. I’d like a border around the day that I can customize the color for maximum contrast.
