1. I just wish there was a way to have the multi day events that have a specific start and stop time be pushed to the top bar, like an all day event.Works well to sync Google calendar, Outlook and Windows 10 calendar apps.

2. App did what it was intended for.I have been struggling to get my Outlook calendar to 100% sync with my Google Calendar, so I tried this app and it pulled both my Outlook and my Google calendars in and they update within seconds across my devices.

3. When notifying the developer the response was to vote for it in a blog?! After you pay for premium you find out that this functionality doesn't exist!🗓️ FANTASTIC CALENDAR APP! Of all the calendar apps I've used/purchased, One Calendar is the best! I have the paid version on my phone & laptop and it keeps everything coördinated as it should.

4. In short, this appndoes everything I want, reliable, and looks very good while doing so!This is a very comprehensive calendar app that seamlessly supports both Google calendar as well as Microsoft Exchange/Office 360.

5. If you have multiple calendar apps on your phone, tablet or computer, it will result in multiple reminders.

6. For example, I display events from my Outlook and Google calendars (for different subject areas) in this app and events added via those apps show up almost instantly in this app.

7. Finally, I've found the One Calendar app to rule them all! 🙌I purchased this calendar to resolve a sync issues that I was having with my old calendar app .

8. For reminders from OneCalendar you have to go into the calendar entry to change the reminder time.

9. I use One Calendar daily, with ease.Worth the 1 time price to have it work across all devices.

10. Google and Microsoft calendars just refuse to consistently sync, meaning you have to always double check (rendering syncing less useful between the two).

11. Out of all the calendar apps I've used, this is the easiest to read and see.
