User Reviews

Most reviews focus on reliability problems, especially data loss where events and reminders vanish, and instability such as crashes. Time zone bugs and post-update UI changes worsen usability. A few reviewers praise reminders and the visual design, but the recurring theme is that reliability and smooth navigation are the main issues.
Pros
  • Reminders/notifications help you remember tasks and deadlines.
  • Clean, visually appealing interface (looks nice).
  • Core calendar features are straightforward for day-to-day scheduling.
Cons
  • Data loss: events, birthdays, reminders disappearing across updates or randomly.
  • Instability/crashes: app freezes or crashes when performing actions (e.g., inviting others, with Exchange calendars).
  • Time zone handling issues: times/dates not staying correct or not adjusting with time zones, and old event times being reused.
  • Negative updates/UI changes: new design/depreciated readability reduce usability and intuitiveness.
  • Limited/buggy view and navigation: lack of full-week view, difficulties editing in Month view, and occasional search/navigation issues.

I’m having a hard time sharing my calendar events with my husband, he gets them doubled to him! When he sends them to me, they come doubled. When I go to delete one, it deletes both. It worked at first but now it’s doing this. We have had fights over it as I’m OCD and can’t do two items the same in my calendar! Please someone help me with this issue. We do a lot of things and he’s always asking me what are you doing today? I have also lost the ability to color code events, it only gives me 5 colors and no where can I add any. Frustrating and I will not go to Google Calendar, it’s crazy to try to navigate.

Lacks many tools other apps, like google calendar, have. The coloring system, the event details, the actual mechanics, everything is just lacking. I was going to say maybe this app might be good for someone just logging some sporadic events in their personal life, but even that is way better on google calendar. Not even the desktop version on the mac gives you more options to customize. And I’m not even going to talk about tracking and reports. Zero capabilities.
