### 1/5 — Cant repeat event without pro

*2026-08-26, version 5.37.35*

Iv been using this app for years and now I suddenly can’t repeat anything without pro. Shocking

### 5/5 — Artem

*2026-08-25, version 5.37.35*

Can’t find the habit tracker in the planner section. Lifetime license

### 5/5 — Great Calendar

*2026-08-25, version 5.37.35*

Nice way to record upcoming events as well as past ones and it is free.

### 5/5 — Great system

*2026-08-25, version 5.37.35*

It’s and easy and great system to use

### 1/5 — Don’t waste your time

*2026-08-25, version 5.37.35*

Basic features such as repeating events, editing synced accounts, and using multiple accounts locked behind ‘pro’ - things that any calendar should contain! Constant popups and interuptions. It’s a calendar, how hard can it be?? I wanted to try a independent creator other than apple and google.

### 5/5 — I LOVE Readdle Calendars

*2026-08-24, version 5.37.35*

I love this app so much! Been using it for years, and the Weekly view is my favourite. I colour code various aspects of my life and can see it all at a glance. I couldn’t live without it, and I’m retired now!! Thanks so much for your wonderful app. PS Your support has been great too when I’ve needed it with syncing issues when Outlook was messing things up!

### 1/5 — Has deleted my schedule

*2026-08-23, version 5.37.35*

For the second time now my whole calendar has been deleted. I’ll have to go old school and use a paper calendar! That’s if I can afford to buy one because I’m going to miss all my appointments and work schedules and possibly lose my job and become homeless. Thanks

### 2/5 — Everything Deleted

*2026-08-22, version 5.37.35*

I have used the app for years. I’ve enjoyed how easy it was to navigate. I kept my entirely life in it. I also own a business and it helped me tremendously to stay on top of things. 

Unfortunately, if I had known that simply going to the settings to unsync my iPhone calendar that it would delete everything within the calendar I would have never paid for the subscription nor downloaded this app.
I didn’t even use my iPhone calendar. I just wanted it unsynced so it would not display the same holidays redundantly in the app calendar or birthdays I didn’t want there. 

Everything is gone. I’m extremely stressed from this as everything was held in this calendar.

### 2/5 — 1 annoying thing

*2026-08-21, version 5.37.34*

It forces you to connect to your other calendars during setup, so, if you wanted it for something separate, you’re out of luck

### 3/5 — Love it but forced to pro to invite some one is a joke

*2026-08-17, version 5.37.34*

I have loved and used this app for YEARS but the recent force to upgrade to pro just to add an invitee to the calendar	item is a non-starter. $21.95 seriously? I am out.
