  1. [R2] Calendars 5/5 · US Excellent: So easy to use, everything color coded makes it easy to see at a glance.
  2. [R5] Calendars 5/5 · US Best calendar app in existence: update: they gave us so many new color options! I still would love to be able to label the colors! Also thanks for bringing the month’s tab back to the lower part of the screen! Makes the UX and UI sooo much better! What a great design team! This is my all time favorite app because it’s soooo much easier to use. Only things I wish it had were more color options an
  3. [R6] Calendars 3/5 · US Don’t bother if looking for free: Can’t even have weekly events repeat without buying Pro. Thanks but no thanks.
  4. [R7] Calendars 1/5 · US Not the best: I have used many calendar apps and you have to pay for repeat events like wth!! Over rated in my opinion. Use time tree!
  5. [R8] Calendars 5/5 · US Love iT: I have been using it for 5 years now. I use it everyday for my crazy work schedule . It works great for me . I love the month at glance !
  6. [R11] Calendars 5/5 · US Not easy to use: This new version is not an improvement. I used Calendars 5 as long as I could. I would prefer a physical date book to this new one.
  7. [R1] Calendars 1/5 · US Disappointed: Had this app for an about two years have lost all of my important dates twice! Look for a better and more reliable app!
  8. [R3] Calendars 3/5 · US Calendars kept dissapearing because you have to have an apple or Google calender already: My whole calender disappeared and the whole reason I had it was because I had deleted the Apple calendars app but it needs it for it to work? Defeats the whole purpose of a calender app
  9. [R9] Calendars 3/5 · US No longer worth the money: I bought this app when it was a one time fee. Then they changed it to a subscription and I paid because it’s what I’m used to. But it is consistently behind in syncing with shared calendars, and my phones calendar now offers all of the same features, further making an annual subscription a waste of money, when I’m having to go into my phone calendar regularly to see thin
  10. [R16] Calendars 1/5 · US Dates are not showing in a widget view: The dates are not showing any more when the app is set a a widget on my phone. It’s just a blank white box.
  11. [R10] Calendars 2/5 · US Free version does not allow recurring events: Looking for free basic cal but lack of ability to make events recurring makes this an incomplete calendar. Other functions seemed great.
  12. [R14] Calendars 5/5 · US Best calendar app!: Not only is the app itself easy to use and fully functional, if there’s ever an issue, their support team is top notch.
  13. [R33] Calendars 3/5 · US Phone Sync: Waaaaaaaa, Calanders worked fine, then one day poof, would not sync with my phone. Tried to reach help but got AI… I have not learned how to talk to AI, ended up with all these things to try…no luck. Try something else, I paid for the year or I would leave.
  14. [R47] Calendars 5/5 · US Best Calendar app ever: I have used this app for several years now. I especially like the fact that I can look at the month and see the beginning text of each scheduled event of the month, so that I can see what event I have planned without digging into the individual date. It synchs perfectly with the Apple calendar so tapping on a date and time in my email creates the event in Calendars automat
  15. [R64] TickTick:To-Do List & Calendar 1/5 · US Not working on Vision Pro: The app crashes on the Vision Pro seconds after it opens. I have asked many times for many months for this to be fixed and I am only told that it is being worked on. I use this on all my platforms and cannot use it on the Vision Pro. PLEASE FIX THIS !
  16. [R13] Calendars 1/5 · US Very Sneaky! Features taken away and locked behind a monthly subscription: I was using this app for a long time on its basic level. Now, after the last “update”, they took several simple features away and locked behind a monthly subscription. Editing colors, multiple alarms for events and reminders have been stripped naked. That’s a hard NO for me. That’s like car manufacturers would suddenly ch
  17. [R40] Calendars 2/5 · US Disappointed: I’m disappointed that Calendars now requires you to upgrade AKA pay, just to have things like family birthdays , repeated yearly, onto your calendar . It used to be free and seems like such a standard , that it still should be
  18. [R20] Calendars 5/5 · US Sync: Been using this app since 2018 and still love it but it’s doesn’t seem to be syncing my changes in this app to my Google Calendar and therefore not on my watch. Maybe it’s just slow?
  19. [R36] Calendars 3/5 · US Works most of the time: I’ve been using this app for a while and it’s definitely caused me some headaches but I haven’t found a layout I like better for seeing all my appointments in one space and being to read them. This app has a rough time syncing between other calendars like your Google and Apple calendar. Beware! I’ve missed some appointments because of this.
  20. [R22] Calendars 2/5 · US User interface: It’s hard to navigate between weeks and I’ve noticed some of my events I’ve made have just disappeared without a trace.
  21. [R24] Calendars 3/5 · US Couple things: Setup is great. 2 things I’m not a fan of. List view shows my todos. I don’t always want to see them so wish I could chose either way. Also it tends to erase my last scheduled items after like 2 years. There have been times I go back to find something from a specific date and it’s gone
