Amazing to centralize calendars across devices
I use Microsoft Exchange for work, Google for personal life and follow other calendars (e.g. church, holidays). I heavily use my calendar for task management keeping them as all-day events that I constantly drag and drop to block time in my calendar to work on tasks, or to put them back as all-day events. I use iPhone, iPad and Windows 10. I’ve tried TONS of calendars to centralize all of them, such as Apple’s, Google’s, Calendars 5, Outlook’s, etc. None of those calendars managed drag and drop of events easily and the views were not good. One Calendar is GREAT. I have the free version for iPhone and iPad, and purchased premium for Windows 10.
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.
