Best experience - Google calendar and Surface Pro

Tried several calendar apps but had poor luck keeping in sync with phone and surface pro. This one seems to work well, update and sync done quickly. Colors help me identify calendar source, which also helps me evaluate event priority. Easy to use. Also would like option to set series for 1st day each month, 2nd, 3rd, etc.

At 69 I need a better memory, this does the job !

The absolute best feature is the ability to Search. A larger range of colors would nice, along with font size changing (tad small on a phone). Much nicer than the pre-loaded calendar program it came with. I highly recommend !

Nice Calender

Good calendar. Easy to choose different views. Much better than the default calendar on Win10. It does take a little bit of experimenting to figure it out since the how to was clear, at least to me. Once I figured it out, I've been pleased. ***They made a few changes to simply set up that I really like. It is much easier to find settings and the sync button. Very good calendar app. Now the only thing it is missing (for me) is the ability to copy an event to another date. It currently allows you to repeat, which isn't the same thing. All-in-all, great app.

Seamless issues with Google Calendar

Installed on with Windows 10, works great and the live tile is great. Great App! Would love to be able to zoom out to see different years. I constantly have to look at the next couple of years to schedule events and having to scroll one month at a time is a bit of a pain. That is my only gripe which is not a major thing for the vast majority of the people who would use it.

Best calendar app on any platform

I use an iPhone every day, a Mac for some work, a PC for other work, my husband's on Android, and we have a lot of calendars to sync. OneCalendar sets the bar. It's so easy to use! The different colors make individual calendars easy to separate with a glance, and it's simple to put a new appointment on any calendar. Outstanding--only calendar I use to organize all the schedules I have to keep track of through my work week.

Really, Really Awesome App

This is a really cool app. You can sync your accounts and keep track of events, birthdays and of course holidays. You can also have your reminders and other info. on your lock screen which is helping me get things done just a little bit quicker. And No one is getting angry with me because I forgot their birthday. I also get a kick out of all the cool colors. Great job guys this is a good one thanks.

PERFECT for my busy work schedule

I'm constantly making business trip plans, I needed something sinced across all devices, with cosmetic options and a widget. This is perfect, attached to my gmail accounts no problem too!

Received Surface Pro for Christmas, and trying to get everything in one place is a little challenging. Now, my calendars, and the calendars of others ARE in one place, thanks to this app. Gave it a 4, only because I've only been using a short time... Now that I've been using this for a while, I think it is better than most of the apps out there. I like the ease of having all the calendars in one place, different colors, and the family can "share" dates by syncing each others calendars.
