Software Reviews and Criticism

  Random Repeatable Crashes iPhone 12 Pro

  iPhone 12 Pro, iOS 14.4 - One Calendar crashes at random times when I switch between viewing modes (list, day, week, month, year). The crash is random but very repeatable and easy to duplicate. A few days ago I sent crash information (screenshot and crash log dump) to the developer but have not received any response whatsoever. When the app doesn’t crash it works alright for a free app. Hopefully the developer will act on the crash information that I provided. ***UPDATE*** Still no response from developer or any update to the app. I could not handle the crashes with the app as they were too frequent. I uninstalled the app and reinstalled the app in an attempt to resolve the crashing issue. Now the app wants to charge me $4.99 to go premium just to gain the features back that I had before. NO WAY will I pay $4.99 for an app that crashes when I change viewing mode. I have moved over to Google Calendar as it has plenty of features and works without crashing. Bye, bye One Calendar!

  Great app for all devices

  To get the most out of this application you’re going to have to buy the premium but it is well worth it. As a college student I constantly switch between my devices (iPhone, iPad, and PC) and OneCalendar is perfectly harmonious with every one of my devices. It’s easy to use, the app syncs fast, and you can link every account you could ever want to use to access birthdays and events. Wonderful app and I would recommend to anyone looking for a simple and effective scheduling tool.

  Good app needs more features

  I have used several different calendars. I really like this one, but don’t like that you can’t copy and paste an event. Would also like the ability to change the calendar that an event is attached to once it is created. I have multiple calendars set up for different people in my family so that I can keep track of their events in addition to my own. But if I accidentally create an event in my calendar and need to change to another calendar, I have to delete the event and recreate it. Overall, I like the look of the calendar and ability to customize the look as well.

  Clean, Uncluttered Design

  I love this calendar app. I appreciate the simplicity and clarity of the display. So many other calendar apps are so complex, offering so many different options, that even the settings are hard to understand. The simplicity of the interface is intended by the developer. Just enough options to have the calendar look the way I want, but not so many options as to make it confusing. The developer is also quick to respond when I have made contact.

  Finally - a calendar which provides applications for my Windows PC, my Windows, and my iOS devices!

  I use a Win 11 laptop, an iPhone, an iPad, and a Windows Mini. I used to rely on iCloud for Windows to integrate my Microsoft calendars with my Microsoft Outlook calendars. Always quirky, it finally stopped working. Now I use this wonderful tool which rapidly presents my Microsoft, Google, and Outlook calendars and lets me update them from every platform. Love the fact that it doesn’t need a browser, but instead provides native apps for Win, iOS, and Windows OS. Thank you, thank you, thank you - well done!! Update: I had one intermittent problem in Windows OS. After a couple of e-mail exchanges, the developer figured out the problem, told me what to do, and now it’s fixed. Couldn’t be happier!
