Dear Readdle!

I love your apps! But, I am hoping you all can offer me some clarification between subscription Calendar VS. Paid Calendars 5.
I paid $30 for Calendars 5. Loved it. But I noticed that Calendars 5 does not have some or the functions that subscription Calendar offers; such as TV Guide and the other special calendars. If I paid $30 for the Calendars 5 app, I feel like I should have access to the special calendars. So, I ended up also purchasing a one year subscription to reg Calendar just because I felt I was missing out on the special calendars. If you’re offering a paid Calendars 5 app that’s $30, shouldn’t that app have it all!? Now I’m not sure which calendar to utilize bc I have purchased both of your calendars. Side notes: Readdle Calendar apps are the best of the best. Otherwise I wouldn’t be writing this excessive review. Also, it would be awesome if you added the ability for users to be able to change the app style; diff colors perhaps. Anywho, I’ll keep giving Readdle my money bc I know I’m getting quality apps. What updates can we look forward to for the new year, Readdle, for Calender/Calendars 5?

Hi, thank you for your kind and detailed feedback about our work ❤️

Indeed, Calendars and Calendars 5 are similar apps however they have few differences. The main difference between the two apps is in their business models. Calendars by Readdle (blue icon) is a free app that lets you easily create events and manage your schedule. The app has an optional premium subscription with advanced features. Calendars 5 (yellow icon) is a one-time purchase.

The only difference is that weather updates and Interesting Calendars are offered only in Calendars by Readdle. If you’d like to have these features, we suggest Calendars by Readdle.
I've also added your request to our Wish List, so our developers will keep it in mind for future updates.

I`d like to suggest you visit our blog or subscribe to our newsletter here to be the first to know about our updates 😊 Best wishes, Alina

I love this app so much that I fought with my company... let me download it on my work phone. Calendar preferences are uniquely personal; as a busy professional, I demand a lot from my time management software. I need to be able to see the days’ meetings in detail, but also simultaneously in week view. This is something I have long lamented about the woefully subpar iCal app: I have to click on individual days to see the events or sacrifice a more bird’s-eye view.

It’s hard to fit both into one phone screen, but Calendars manages splendidly. The trick: vertical week-view lets you see the entire week + each day’s events at once. It’s a UI miracle!

I’ve been using this app exclusively for years now, and it has withstood the test is time, as well as the transition from thinking I was busy in law school to actually being busy at a law firm. This app is free so you should try it and see if it meets your needs. Then, buy the pro subscription (for a measly few dollars) for full blown functionality. There are a million calendar apps out there, but none have made me send protracted emails to IT begging them to let me put it on my work phone. That’s how good it is.

Worth the upgrade cost

I am still not sure almost a decade later why Mac choose to separate out task reminders and the calendar on the desktop. Figuring out when to do the stuff you need to do - and to have it all in one place - seems like the logical efficient approach. Luckily Readle fills this gap really well. I have found the app extremely efficient, and impressively reliable - it updates my iOS calendar instantly- and imports reminders that I write by talking to Siri without a problem. I also integrated my trello calendars without issue etc. My favorite is how easy it is to set multiple reminders. And the logical way you can write a calendar event. Why Apple can’t get this right is just mind boggling. My biggest disappointment is that they don’t have a version of the app for my Mac (as far as I can tell.) It’s not a problem per se., only insofar as I’m spoiled now and really notice all the inefficiency in the old calendar. Ugh. Kudos Readdle, and please let me know if you do make a desktop version - I would happily pay another 15-20 dollars to escape the iOS one!!
