What's New in Chaos Calendar
1.14
October 20, 2026
We've made improvements in this version for iPad users who resize the app window while in the middle of using the app so it keeps your place when the app window compacts to or expands from a stacked view (like most iPhones) instead of the side by side panels. We've also made updates so this app will be ready for the new iPhone Duo foldable!
