OMG it is perfect!!

I was going crazy with the bad graphics of the native windows 10 mobile calendar app. This app has solved all these problems. Graphically wonderful. Clean and so easy to read and customize. Solved the problem of windows calendar and mail app themes being linked. Can now configure the calendar just how I like it without affecting the mail app. I am so pleased. Finally a developer with great graphic sense and who gave us the ability to customize. One feature request. Give us the option to choose to have days that have past get grayed out so that one can VERY quickly see where we are in a month view. Thanks for your great creation.

Pretty good

I love that it syncs with all my calendars. What I don't like, is there is no way to change the alarm when your appt. is alerted.

Perfect calendar for windows 10

This calendar has a lot of versatility, makes appointment making easy and birthday reminders are a breeze with this.

It works well, I like it

It's very functional, allows me to pull in multiple google calendars, outlook 365 etc... I live by my calendar, but use multiple to keep work/play/family time organized and shared with the appropriate need to know parties and this does that terrifically. UI leaves much to be desired in terms of aesthetics, but for free you can't really complain too much. I'd like to see better theme options, or at the very least more color choices to match my windows theme. Putting the color selection tool into a color wheel format or RGB/HSV sliders would help tremendously. Adding a "To do" functionality/task list would be great also.

Excellent app

Syncs well. Easy set-up. I would give it five stars if they added darker colors for the events.

Seems to be a great app!

I like that you can immediately sync you Google Calendar. With the Win 10 Calendar app you have to wait a bit for the new appointments to show up. I like the calendar app on Win 10 - it is "prettier", but this app seems more functional. I also like that you can see a list of appointments on the Live Tile on the Start Menu. The built in Win 10 app doesn't.

Good but slightly messy

The app itself is good, I like the fact that I can see up to 4 appointments in a day in month view (MS Calendar shows 2 1/2), but it's generally a bit messy: the font is too big (would be nice to change the font size); background colour in appointments gives me headaches (I have around 7 calendars and the colour mix is too much), maybe would be nice to choose whether to display a colour block behind the appointment or colour just the text (like MS Calendar); week number in Italy is not used that much, so that info just takes up space (would be nice to turn it off). All this makes the page a bit messy, so "only" 4 stars instead of 5.

needs work

The app could use a 4 week feature like in Google Calendar. Also the colors are way too bold for appointments. Only the ALL DAY events need to be color barred. Hourly events should be just printed in color without the background.

Like, dude...

All I need say, is that this "thing" blew my mind. Best calendar/schedule app out there... I can't possibly ask for more. -Thanks Spark!

I think it is great

To be honest, I didn't know about One Calendar until Microsoft went and messed up Microsoft Mail & Calendar to where I couldn't use it. So, I went to the app store and downloaded One Calendar and it does everything I use a calendar for. It sync'd with my Hotmail calendar and you can add different accounts, what else could you ask for. Thanks. Now as of 11/20/15 Microsoft Live changed their Outlook format online, now Live won't let One Calendar access, or sync with My Microsoft Live Account.
