  8. [R1] 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.
  9. [R3] 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.
  10. [R5] Calendar · Planner & Reminders 4/5 · US Good but needs some fixes: Basically once a year this app deletes ALL of the stuff I’ve entered into my calendar. It is so stressful and inconvenient. I try to click the “missing calendars?” Button and it never opens to anything. And now all of my birthdays that I’ve been adding for years are also gone.
  11. [R6] Calendar · Planner & Reminders 3/5 · US starting to go bad: it used to work super well, but as of recently every time i open the app i have to "restore" my subscription, and all of my calender notes keep deleting. i missed 2 events because they're deleting from my calender after i KNOW i put them in there.
  12. [R7] Calendar · Planner & Reminders 1/5 · US Ads?: Why do I get ads? I pay for subscription
  13. [R10] 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
  14. [R19] Calendar · Planner & Reminders 1/5 · US Restore Purchases sometimes doesn’t work & no reminders: Clicking the reminders check box does nothing and can’t get reminders showing in the calendar anymore. Even though I’ve paid, sometimes I get loads of ads. Happy to change my review to 5 stars if these are fixed permanently. Tried to contact the company via their website form, but after submitting it says, “There was a problem sending your m
  15. [R60] Calendar · Planner & Reminders 1/5 · US TRY TO MAKE YOU PAY TWICE!!!: I have a subscription to this app that is paid up till 2027. However, it is suddenly acting like I have no subscription and showing me the most annoying ads. When I try to get rid of the ads, it tells me that I have to sign up for a new subscription. I have done some research and found out that I’m not the only one having this problem. I have contacted the developers
  16. [R76] Cozi Family Organizer 1/5 · US No customer service: I’ve used this app since 2012, 14 years!!!! Has been amazing, but had an issue and the help link immediately sends you to a blank web site but won’t let you click the links within the help page on the app. I’ve been charged twice! $39. So if it doesn’t get resolved, they may have charged me $78, but it’ll be the end of our 14 year relationship and they won’t get any more refer
  17. [R69] Cozi Family Organizer 3/5 · US I LOVE IT BUT….: I really do love this app! I’ve had it for many years w/o issue. The shared calendar & grocery list are at the top. I’ve always used the free version. A couple of years ago we had no choice. Pay $40 annually or delete the app. I really think my time here is limited.
  18. [R120] Cozi Family Organizer 3/5 · GB Full calendar appears to have been reinstated again for the free version: I’ve been using Cozi for several years now - just the free version. It’s been really handy, but now they have suddenly stopped allowing you to access more than 30 days ahead without paying to upgrade to Gold! Which means I can’t now access all my diary entries past mid-June. The free version only gives you 30 days! Who wants
  19. [R87] Cozi Family Organizer 3/5 · US Cozi: Been with Cozi a very long time. It’s made changes but so far not affecting me until now. Kept wanting me to sign on and when I did it said wrong password. It wasn’t. But I ended up having to sign up again and new password. Tried reaching out to anyone but there is no way to contact Cozi if you have issues. That’s my beef.
