  1. [R1] Calendars 1/5 · US Lost info: I lost every entry on my IPhone calendar 5 days ago
  2. [R12] Calendars 3/5 · US Not sure what happened: I’ve been using this calendar for years and have LOVED IT. Randomly in the last week, my calendar events all disappeared. iCloud backup is on and everything so I have no idea where it all went and it was really stressful. If someone reads this, I would love some help because I WANT to keep using this app!!!
  3. [R18] Calendars 3/5 · GB Good but it goes missing: I use this calendar for my classes and quite often classes go missing, disappear which is very annoying. I pay for this app so this shouldn’t happen at all.
  4. [R25] Calendars 2/5 · US Everything keeps getting wiped.: I really like this app so i ended up buying the premium, ever since then there have been a couple times where i open up the app and literally every event or task or anything is deleted. I have a bad memory which is why i yknow use a calendar, i cant keep re entering every single event including every one of my friends and familys birthdays.
  5. [R3] Calendars 3/5 · US Nice app when it works: I’ve been using Calendars/Readdle for maybe four years now? Primarily was using it on my iPhone, but began using it on my MacBook and liked the integration across the two devices. The past several months, it feels like the desktop version has not been updated or has been more glitchy than normal. I am not able to drag the window around, and it seems like it’s crashing my co
  6. [R9] Calendars 3/5 · US Something has happened…: This, and Calendars 5 (the predecessor), have been my go to phone calendar app for years. But recently, it been consistently boning me, by not updating my calendars in the cloud, and not being updated by them. (Multiple calendars, iCloud & Google) I’d love a force sync button or something. Too many times lately, I’ve put things in, or changed them, and it the next day or t
  7. [R16] Calendars 2/5 · US Calendars don’t sync.: I cannot figure out why the app looks one way on my iPad and a completely different way on my iPhone. As of now, I can see a full list of tasks that I created on my iPad but when I open the app on the iPhone, there’s no tab for tasks. I had and paid for calendar 5 but then had to switch to this one because the first one was no longer gonna be supported. Can somebody please
  8. [R33] Calendars 3/5 · GB Poor synchronizing: The synchronizing off my items in-between the devices doesn’t seem to go automatically. I have to open the iOS calendar to synchronise my items. Defeats the purpose of having your “Calendars”
  9. [R4] 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
  10. [R6] Calendars 3/5 · US Great, wud like few more features in free version: Overall good app. I use this on my phone since other calendar apps won’t link w my fam, not sure why. This has been lifesaver for connectivity. Unfortunate that basic desk-top features aren’t available on mobile version- such as setting recurring mtgs (only w “Premium”-fee mobile version). Can’t delete individual items from “pre-made” calendars- i
  11. [R13] Calendars 1/5 · US money-blind company: money-blind company
  12. [R19] Calendars 1/5 · US Regret of any past payment for this xhit: After paid again and again you can’t even set up repeat event . Go to heil
  13. [R8] Calendars 4/5 · US What’s going on?: Why is all this junk being added to my Calendar? I have notices from like 4-5 security places that tells me my subscriptions will be renewed and taken out of my bank! Other notices all spam now added to my calendar! Don’t need that so I will have to delete this one and try another app since who needs more junk coming into our lives?
  14. [R10] Calendars 1/5 · US Lots of spam: I had loved this app until 2 mos ago.. I got tons of spam alerts that went directly into my calendar day, not text message, not email, but This calendar app, 8-10 spam messages a day. I finally had to transfer all of my events to calendar that comes with the iPhone. Very sad to have to delete this app, especially after just paying for another year recently, but now, No spam alerts.
  15. [R14] Calendars 4/5 · US Holiday calendar: I like the calendar, however, I have opted out of the holidays. There are some very questionable holidays that ate automatically inserted. I suggest now that we have option to choose.
  16. [R39] Calendars 1/5 · US Bad service: Someone was able to get in and my calendar and now I have a reminder every single day for the next forever how long about a bill I don’t owe and I can’t erase it
  17. [R5] Calendars 4/5 · US Crashes on app startup(fixed after an update): The app has been crashing for the last two weeks and no fix has been pushed for it
  18. [R7] Calendars 1/5 · US Used to love it: Was my first go calendar, until recently. All the drag and drop features disappeared. You can’t double click on calendar events and have them open in month view. Just a big loss of features. If it gained them back, I’d keep the subscription. Used to be worth it. Apple Calendar is just as bad.
  19. [R34] Calendars 2/5 · US What happened??: The latest updates have made this app practically unusable. It’s so tedious to navigate now, and ridiculously buggy - the worst being a daily app freeze often requiring a hard reboot of my phone just to restore usage.
  20. [R52] Structured 5/5 · US Love: I've been using Structured every day for a couple years now. It's very straightforward to use and the UI isn't overwhelming. Plus, the team actually takes user feedback into consideration when updating the app.
  21. [R53] Structured 3/5 · US Good but could use improvement.: I am trying this app out, but find myself severely disappointed in how app handles “overlapping” tasks. I juggle 2 jobs with variable schedules, and have ADHD which this app claims to be aimed at, so I schedule out work shifts in my calendar so I visualize my week and plan other events around them. I want to be able to nest work tasks within that scheduled time, bu
  22. [R54] Structured 2/5 · US Free version too limited: Can only add 3 events per day with the free version. Want you to pay $30/year. No way to hide the AI button in the middle of the screen that you need to pay for.
  23. [R56] Structured 1/5 · US Too expensive: The price for this ?!? Ridiculously expensive
  24. [R65] Google Calendar 1/5 · US Color Update Broke Colors: The update for the desktop app broke colors. There is no consistency between the colors in the iOS app and the desktop version of calendar. Furthermore, custom colors that are available on desktop are not on the app. This update ruined the organization of my calendar.
  25. [R66] Google Calendar 4/5 · US Needs better notifications sound: Sync is faster than apples calendar app. However the notification sound is very tame and quiet. Not customizable at all.
  26. [R67] Google Calendar 3/5 · US Give Me All The Colors: I love google calendar but I wish I had all the color options that are available when picking the default calendar color for when I am picking my event colors. They are so much prettier and give more variety for the various types of events with a shared calendar. Please let me do this
  27. [R68] Google Calendar 2/5 · US Colors disappeared: Where did the color options for markings go? Now there's only one default color. · translated
  28. [R79] 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.
  29. [R80] Calendar · Planner & Reminders 5/5 · US Reeee-View: Great App to keep ur Bills from bumping into your Oops and ur Laters fom bumping into your Nows!
  30. [R81] 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.
  31. [R82] Calendar · Planner & Reminders 2/5 · US Missing part of words: Don’t like the look
  32. [R93] TickTick:To-Do List & Calendar 1/5 · US Sloppy for overnight workers.: Doesn’t properly add overnight events to the calendar..:treats them as another event past midnight which clutters the calendar and makes you look busier than you actually are. A major critical flaw and won’t be subbing because of that. Good thing a trial was offered.
  33. [R94] TickTick:To-Do List & Calendar 5/5 · US Best App: Best App to keep reminders for
  34. [R95] TickTick:To-Do List & Calendar 3/5 · US So good: I will send reminders like when it would be a good time to drink water
  35. [R96] TickTick:To-Do List & Calendar 2/5 · US Not smooth: Interface is just way too much. Needs to be streamlined massively. Better apps are just like your calendar with two buttons on the side. That's it. Ticktick has like ten pages of shi
  36. [R107] PocketLife Calendar 1/5 · US Hit by Scam: As soon as my calendar was linked, I was hit by a scam.
  37. [R108] PocketLife Calendar 5/5 · US Diana: I love this calendar but maybe in future you could add a drop down box for notes on each day. That would be so helpful for those of us with a bad memory.
  38. [R109] PocketLife Calendar 3/5 · US Overall good App but missing a core feature: Reminders showing inside widget would be a core feature to add will attract a-lot of fantastical calendar users like me since they messed up their widget
  39. [R110] PocketLife Calendar 1/5 · US What is going on: I’ve been using and paying for this app for years then all of a sudden all my schedules have been deleted. Idk how to fix this.
  40. [R15] Calendars 3/5 · GB Love this app but home screen widgets won’t appear: I originally got this as a free upgrade and seem to recall that didn’t include the home screen widgets but I’m now on a paid subscription and the widgets still won’t appear. What to do?
  41. [R37] Calendars 1/5 · US new update makes recurring events require subscription: new update makes recurring events require subscription, deleting and getting something else. i can vibe code a calendar app myself if i want lol
  42. [R47] Calendars 2/5 · GB Great app but basic features paywalled: Used the upgrade from the older app and now the free year has expired, it shows how many features are hidden behind pro. Basic features such as invite someone to the event you just added. Back to Calendars 5 it is.
  43. [R61] Structured 5/5 · US LOVEEE: I have been using this app for over a year now and I love it so much. It helps me plan my day a lot easier than any other way. One thing I do wish was that you could just write things down without worrying about putting a time down. Thats my only complaint tho and I love every other thing about structured! (Update I learned you actually can do that nvm!) I love the app even more now!
  44. [R62] Structured 1/5 · US You can do better: As a Person with severe ADHD, I think this app is not giving me the opportunity to be organized. Without the Structured Pro plan, I can’t repeat some of the tasks that I need to do on a daily basis. To be honest, I do not have the money and patience for having to pay for this pro to only get 2 things unlocked. I know you guys got an Apple Award but the only award I would be givi
  45. [R63] Structured 5/5 · US ADHD girlies, sign up now!: I am fortunate to be an OG lifetime membership user. I believe I got the pro plan early on for something like $20. I have since converted at least a dozen of my close friends and family. This is a perfect app that only continues to grow, improve, and impress. I could not function without it and I could not recommend it enough! The mobile version has reshaped how I can
