About One Calendar:

the place where all your schedules are harmoniously grouped and performed. It’s you who chooses which calendars will be displayed in the application and on its widgets. And you can also create new calendars and appointments right from the application.

Registration will take no more than a couple of minutes – depending on how many calendar accounts you will connect.


One Calendar has a lot of flexible settings. Choose the type of presentation you want and customize colors and other design elements. The large fonts are very eye-friendly. As for the color choice – there are two to five shades for each main color. So you will not have any problems distinguishing between types of activities with hues.

The themes are also highly customizable; you can choose a foreground color, an additional one, a background pattern, transparency, style, and many more options.


Why One Calendar:

The One Calendar app is simple and easy to use. It’s the only calendar app to combine so many different calendar sources and also the only one running on all platforms; Windows, Android, iOS, and macOS. This is due to the fact that we are using one codebase and doing all synchronization in the app instead of in the operating system.



One Calendar has an excellent support team that can be reached anytime via email support system. In my experience, they proved themselves to be very helpful and quick to respond. They resolved every last problem that I had set up.
One Calendar is one of the few calendar app that offers full 24/7 email support. I have found their support department to be very quick to solve issues, especially when it comes to handling site-specific issues or anything other than answering generic tech queries.

Affordable Price

One Calendar proudly claims themselves as one of the most cost-effective calendar app on the whole market. And to be fair, they do a pretty good job of keeping that claim factual.
Something that makes Calendar app unique is that their prices are displayed clearly and openly on its Google app store for their visitor. I think One Calendar deserves the praise for doing this.
None of One Calendar’s competitors have this level and type of transparency. Other competitors will hide the prices or make you sign up before you can even see them. This is often done to sneak in hidden charges that they don’t want to reveal until they’ve gotten you to register (and partially commit to going with them).

Our Experience:

There was no drawback up to this point, to be exact. It was easy to set up thanks to their support team, and the processing power was on-par with other similar apps available in the app store.
