Calendars 5 and Fantastical are pretty good alternatives.
Fantastical (I think it is $4.99) has a bigger focus on representing events through lists. The Dayticker is a really quick way to navigate between days, but its color-coded representation of days is weird (sequential events appear to overlap with one another). Its monthly view is color-coded as well, so you can see what types and approximate how many events you have on each day. Natural language processing is great. Its app icon badge can be used to show today's date or the number of remaining events in the day.
Calendars 5 ($4.99) is pretty good as well. I just downloaded it, and it is much more flexible in terms of providing you multiple ways to see your events. You have the typical list view that continuously scrolls through multiple days. You have a Day view to see a visual timeline of your day. You have a condensed Week view in portrait mode on the iPhone where each event occupies same-sized boxes. The landscape Week view is basically Day View but with multiple days showing up. Month view gives you lists of events, and it may seem cluttered at first, but you can pinch to zoom into each day. It also has natural language processing, and includes a section for tasks/reminders as well.
I previously used Fantastical but then moved on to Calendars 5 because Calendars 5 is more flexible and does not rely on lists as much.
Hope this helps! 🙂
