  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. [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.
  6. [R17] Calendars 5/5 · US Practical: It makes my life more easy!!
  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. [R4] Calendars 1/5 · US Could not even use because it wouldn’t load: Just like the title says.
  10. [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
  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. [R38] Calendars 4/5 · US Too Dark: Love the Calendar, but I’m still trying to get the background lighter. The developer sent a note and his suggestion worked perfect.
  14. [R45] 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.
  15. [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
  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. [R46] Calendars 1/5 · US Blocking things behind a paywall that should not be: There are some basic features that are blocked behind a paywall that should not be. Feature 1. Being able to set multiple notifications separated to keep you reminded about what you need to do. Say you have an appointment at 6 pm and you want a reminder 1 hour from it, 30 minutes from it, and 15 minutes from it. You have to choose one of them o
  18. [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.
  19. [R19] Calendars 1/5 · US Spam spam spam: When I bought the older version of this app a long time ago I was happy to have something that worked well and software I owned. Since then all they do is spam you to download their other apps. F off
  20. [R58] Calendars 1/5 · US Harassment: I’ve been a user of this app for years and have the lifetime access. After a new update I am consistently harassed to “upgrade” even though I have lifetime pro access. It will block features from me until I close the app and reopen it. I’m worried that either myself or my wife is going to accidentally hit subscribe and end up paying for an app we paid for life years ago. People who sup
