★★★★★ The push notification requesting access to my calendar just flashes on the screen and automatically denies access to my calendar.. Which ruins the whole point of the app. I just wasted my money.

3 of the 1 and 2 star reviews.
★★★★★ While a great deal of care was taken in the planning and execution of this program it lacks the flexibility to completely tailor the interface to an individuals needs.
★★★★★ When I started using the iPad the only thing I was missing and I really needed was the ability to invite attendees.
★★★★★ OK BUT CAN NOT CUSTOMIZE A LOT. CAN NOT ADD PARTICIPANTS TO EVENT. @@@@@@ BIGGEST ISSUE IS THAT ALERTS DO NOT WORK IF APP IS CLOSED. APP HAS TO BE OPEN TO GET THE ALERTS MAKES IT PRETTY USELESS. @@@@@@@@@

Latest reviews, Germany App Store.
This app was designed for an iPhone and then ported to an iPad. There are lots of wasted space. The design need to be re-thought as to how to take advantage of the additional screen real estate available on an iPad.
I simply appreciate this app. It works within the rules/structure that Apple controls and does a beautiful job. I use this app daily. I’m pleased, nuf’ said.
I’m new to iOS and have had problems finding a replacement for my beloved a+ calendar app on Android. I bought the Extreme Week calendar and ready liked it. I thought the upgrade would give me everything else I wanted. The tasks don’t pull from my Gmail calendar and the month view is only 1/2 screen vs the whole screen. Very disappointed in wasting money on the upgrade.
Updated review: After downloading the 2nd iOS update to 13.1, the makers of my favorite calendar/agenda app have done an app update & thank goodness I can now save new appointments and save updated/changes to appointments that had to be changed. I am so grateful this has been fixed! Thank you. Been an app user for many years, but ever since I downloaded the iPhone iOS 13 update, I cannot SAVE anything on the Extreme Calendar app. Cannot save new appointments or change existing appointment date, time, etc. Also app crashes when I click on “email support”. Please help ASAP!
I have used this app for years and love the customization with categories and colors. However, since the last iOS update I am no longer able to add new calendar items. The option to save a new entry is gone. I would give this app 5 stars as soon as it is working properly again.
Make this avail easy as a widget! And you’re golden
