This had been my go to app for years. I have to manage a fairly complicated schedule and this has always worked the best for me with it's form and function. However, the newest version has undone all of that. While I agree the GUI needed a refreshing, some of the changes make no sense as it took away features. The day view is just bad now; overlapping events are just odd and most of the text gets cut off. You also used to be able to double tap on a day when viewing in month mode and it would take you to the day in day view, but now it brings up a pop up window that is just a cluttered mess. Same thing when you tap on an event. I'm not even sure how many years I've used this app as my daily driver, but unfortunately with the redesign I will no longer be using it as it's just cumbersome now.

You can (just as before) swipe from month view directly into any date's day view. You can just as before tap on a day to open the event details. Event details are now in a different design, which allows for much better navigation between events and much better overview for packed days where events are cut off in week or month view.

(updated) I read the help (what an idea!) and the recommendation to clear and re-sync calendar storage worked. repeat events now work as expected. whoo! this is a really great app, I'd be lost without it. (original) repeat events won't save after the upgrade. I've been using this app for years and never had this problem in the old version.

I've used aCalendar for a few years. It's always worked well, but the style was always ho-hum (especially the agenda widget). Still, I've tried more calendar apps than I'm proud to admit, usually in search of a more stylistically attractive app, and I always came back to this one. Well, they just did a visual overhaul and it jolted me into finally writing a review. It looks great, it works great, not sure what else you can ask for.
