Is there anything new? Please tell everyone.

Backward step! Had this app on previous phone, Samsung A70, upgraded to Samsung A73 cloning old phone settings & google account to new phone but sadly this app lost translucent background setting in the changeover so am now stuck with boring white background unless I pay for premium. Not happy.

Finally a calender I like. Great subtle lavender and lilac colors. I set it on weekly setting Very clear and easy to read Finally!

Very useful, no nonsense. That says it all. Very useful to aggregate multiple calendars from multiple accounts, and also from other sources (ical feeds published by college clubs, for example). Suggestions for future improvement: - Ability to sync more frequently than every hour - Filter on/off calendars individually, rather than grouped by color

Simple and effective. Nothing fancy. Connects all my calendars in one place. Makes me happy. Ad Free, the way I like it.

Totally useless because it depends on other calendars if you want to do ANYTHING besides just looking at dates.

Excellent app with many useful features, have been using it for years and highly recommend it. I recently had reason to contact support - it was actually an issue of my own making but they were very responsive and helpful, eager to find a solution.

Not only is One Calendar a great app with great support, but from what I can tell its the only one that can combine Google and Outlook calendars without having to do a direct sync between them to get Outlook on an Android device. I like having a monthly calendar widget and this is the only one that works for me. Most others will only include the Outlook calendar if it is synchronized with Google directly. Ideally Outlook would have its own monthly calendar widget but they choose not to.

Unable to do anything with this. It does nothing. Cannot add any events. Cannot change the theme after accidentally selecting one from the initial start up options. It's gone.

Attractive and mostly clear interface. Calendar management options a bit simple. This connects to anything and you dont need a third party CalDAV connector. That makes it well worth the money. Devs cannot always work for free, just like anyone else. On the downside the app is quite big (134mb on my phone) and the Xamarin framework pulls in all the tracking info. Its MS for you. Website looks a bit neglected. This is a tiny market. Please support your independent app devloper.

Best calendar app I've found for synchronising my many calendar accounts between my phone and Chromebook and viewing them all in one place.
