Genius and one of a kind. Perfect.

Im beyond grateful I came across this app in the App Store. Apple just changed their Calendar app with the new iOS update and I was using that app for everything and now it sucks and it’s just like every other calendar app now and I hate it. This app is like the previous Apple calendar app but even better because there’s worded event previews on all days of the month when viewing the whole month. I also think the events of the day are slightly more readable than Apple’s previous calendar. I was able to successfully connect my Apple calendar events to this app for a quick, seamless calendar transition. This app means so much to me because that Apple calendar app had my whole life in it and no other calendar app works for my brain. This app is my only hope now for scheduling and organizing my life so I hope they don’t change it to be like anyone else or anything because this works great and it’s better than all the others in my opinion. It’s extremely methodical and organized to me. Im actually able to sigh with relief while managing my life with this app because it’s perfect to me. I hate that other calendars have too many colors (distracting) and timelines (focused on the wrong things) and they don’t have it where you can view the whole day and the whole month at the same time (you can’t see the whole picture). I’m so grateful this app is free and the developers told me it’s going to stay free. The ads don’t even ruin the experience like some other calendar apps. Give this app a try.

Disgusting ads

Calendar is fine. No option to share with a family member. Worst part are the ads. They are pornographic. I have kids and I have to keep them away when I open the app bc I don’t know what kind of nasty ads will pop up. Denigrating women isn’t something I want in a stupid calendar app. Do your job. Just be a calendar.
Some pervert must have designed this app.
