Software Reviews and Criticism

  • By JuliaEspinosa

    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 Windows 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 Microsoft 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 Windows (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!!

    Not meeting my needs

    This might work very well for many, just not me. I’m not even sure why, I am not niche in my needs. I find where I used to do somethings with ease (reoccurring calendar items) now it has been locked away for paying members. I like to tap on the day I need an appointment to make the date. Instead, if I am not paying attention ( busily trying to record an appointment while being rushed out of the dentist office,) a March 20th appointment becomes a March 1st. Because it makes the user manually scroll through even when they click the exact day they want the appointment. I need more control to see MY dates on the calendar instead of the preset holidays and observances. As I write this, I can’t see my feb 14th zoom meeting because they have 2 different listings for Vday that takes up the place on the visible square. The ability to easily discern that there are more scheduled events in a given day is not there. The month view, the day had special global observances that I didn’t care about and (couldn’t delete), that ranks higher than seeing what I manually typed in. I am actively searching for a better app for my needs, and just based on personal experience, would not recommend this app.

    Very upset

    Are used to think that this calendar program was the best one out there. I thought so highly of it that I purchased the full version. It worked great for a while. Then it started duplicating the events every time there was an update, or changing the dates in the future years for recurrent dates. It became quite cumbersome to keep going back and fixing everything every time there was an update. I contacted you about this and you tried to troubleshoot it saying that it wasn’t working right because of the calendar program that comes with the iPad. I did everything that you asked me trying to fix problem. But the problem still occurs. Tonight I thought I would uninstall it completely and then go and reinstall it and start all over again to try and see if that would fix the program. Even though it would be annoying and cumbersome to re-enter all of my dates and events, I thought to try that. Guess what? I can’t reinstall it without paying for it again. This has me even more annoyed. I paid for something that I now cannot access. And even though it didn’t work the way it should I still prefer it to any other calendar program out there. Guess I’m just out of luck. Very unhappy.

    Excellent App! Just one question... (see bottom)

    First I just want to say that this app his single-handedly changed my life. I have it always showing on the face of my Microsoft Watch, as well as have reminders on my phone and iPad. I have a lot of trouble keeping myself in a routine, and due to that it is very difficult to manage everything I need to do; I often find myself falling short. I use this app to schedule my days a week at a time, with everything from “Shower” to “Eat lunch” to “Meditate” to “Work” to appointments/etc. The User Interface is unparalleled - it is very easy to quickly read and comprehend the various items on my schedule, they are all color-coded and laid out beautifully in whichever view-setting or device I am using. Then there is the actual depth and the functionality of this app, both of which are in abundance. I can do (almost) anything I want in terms of managing my calendars/schedules/items, with a comprehensive “Repeat” algorithm - to just name one example - and an incredible level of integration into my devices’ software. NOW this brings me to my question: Is there any way to create multiple, separate calendars that do not interact with each other, and that I could switch between easily? (So for example view Calendar A only, use it 90% of the time, but then have a separate Calendar B that I can occasionally swap into view for a totally different set of blocks/events.)
