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.

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!

Very Good Workable App!!

I would rate this app good, even though I've only had for a couple days. I need to take it through its paces before I can file a review. UPDATE: I find the synchronization properties of this app awesome. The app helps me keep appointments because it's connected to my phone's lock screen and I never miss a date! Outstanding!!! I have had the app for about eight weeks now, it is still the best! I've had to download it to my laptop again but it still works the same. The best apps are the simplest.

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.

Better than built in calendars

Locked into time increments - need to be able to select something other than on the quarter hour; no ability to set repeating events; need more flexibility in setting reminder times. Need to allow for "calendars" created by the user - for example - "Anniversaries" "Class xxx"; I have a number of different calendars set up to make it simpler for me to track events - if there is a way to choose from more than one calendar, have not found that flexibility.

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.

Great app for basic planning

I love that it coordinates with all my calendars. It is aesthetically pleasing and easy to read/use. I wish I could view more items for each day.
