  1. [R2] Calendar 4/5 · US Good but add specific times for events not just times that end in zeros and fives: Wonderful organization but add specific times for events not just times that end in zeros and fives and stickers and more colors that personalize it
  2. [R3] Calendar 3/5 · US I’d like a refund: I like this app, I use it for everything. I would like more access to change things; example: how are Jewish and Islamic holidays considered “U.S. Holiday” ( which is not true) and I can’t remove the holiday so it’s not in my calendar reminder
  3. [R5] Calendar 4/5 · US Decent but needs improvement: Widgets need more options. Specifically, you should be able to mark a reminder complete by clicking on it in the widget. You should not have to open the app to mark a reminder complete. Also, need a widget that shows events in a month/weeks long calendar view. Something other apps offer.
  4. [R6] Calendar 3/5 · US Optional Holidays: Apple, please make it possible to filter different holidays. We don’t all want to see Christian, Jewish, and Islamic holidays wholesale or none at all. Please add filters!
  5. [R8] Calendar 4/5 · US Almost Perfect for Any Apple User: Apple’s calendar app has one leg up over the competition, and that is the integration with its products and services. I can ask Siri for the next event on my calendar from any of my Apple devices, and I can get personalized suggestions for new events as well based on conversations in iMessages or Apple Mail. There is one problem with this app, though, and it is t
  6. [R9] Calendar 3/5 · US Update failure: Not happy Can not sort any more I updatedmy phone and transferred all apps. Why can’t I search for prior events
  7. [R13] Calendar 1/5 · US Confusing for me: I might just be bad at navigating, but I hate using this app. It requires some scrolling and clicking small buttons, which is not my kind of thing. I tried to add a new calendar but it didn’t even alert me and a birthday was still there.
  8. [R18] Calendar 3/5 · US Requires Manual Intervention: Pro: I think you’re able to add pics/attachments unlike Google. Cons: Notifications won’t go away until you touch it. Some apps will only use Apple even though I prefer Google, and I have to manually sync every single important event because it defaults to the wrong calendar.
  9. [R1] Calendar 1/5 · US Frustrating: All my events are gone, and are no where to be found. Incredibly frustrating
  10. [R4] Calendar 2/5 · US Whyyyy: Why whole calendar keeps getting deleted I feel like every other week…
  11. [R7] Calendar 1/5 · US Alerts don't work: My alerts don't work like they use too!! Apple sucks!!
  12. [R10] Calendar 1/5 · US Disappear: I used to like this calendar. Not anymore. I constantly lose my past schedules. It is July 2026 and June 2026 is gone. I schedule reminders for Birthday’s. They never happen.
  13. [R61] Calendar · Planner & Reminders 2/5 · US Not Getting What I Paid For Again: I paid for the Pro version of this app, and I am experiencing for the third time this year not getting what I have paid for. When I use the contact link on the developer site, I continually get an error that my message cannot be sent. This app is fine if you don’t mind constant ads but be aware that you will get them even if you pay not to.
  14. [R63] Calendar · Planner & Reminders 3/5 · US Good but…: I love this app but it constantly makes me “restore” my subscription. Which is not a be deal in theory, but when you have to pull up your calendar fast but then have watch a one minute ad (when you pay 5 dollars a month), it’s not ideal… please fix this problem!! I might have to look for another calendar app if it’s not resolved.
  15. [R67] Calendar · Planner & Reminders 1/5 · US Ads?: Why do I get ads? I pay for subscription
  16. [R70] Calendar · Planner & Reminders 2/5 · US Pop ups?: Not sure why you get a pop up every time you open the calendar? I payed for the premium subscription and still get pop ups? Very disappointing
  17. [R20] Calendar 4/5 · US Very useful in iPad: This is a great app on iPad due to being able to use it in landscape mode and the bigger screen real estate. Would really really like the ability to edit (and delete) unwanted holidays. They get in the way and it would very useful to be able to reclaim the screen space they take up.
  18. [R40] Calendar 1/5 · US Sexual Calendar Entries Allowed: Allows uninvited calendar entries to show up on the calendar from junk mail. I have a whole bunch of junk email every day with people sending nasty calendar invites that I have never accepted showing up with sexual meeting invites that I cannot make go away they just keep showing up on the calendar, making it useless to use without seeing these things. The whole
  19. [R16] Calendar 1/5 · US Rouge Calendar: Just recently whenever I put Inneh project item, reminder event it always and save the information it erases all my login information on Calendar. Something needs to be done to fix this bug.
  20. [R45] Calendar 3/5 · US Good, except…: I don’t want islamic anything on my phone, ect. How do I remove them?
