Release 3.0 delivered an enhanced user experience. Algorithm updates included comprehension of army size to automatically adjust radio buttons, as well as providing a more readable Battle Summary. This release (4.0) provides everything release 3.0 did, plus the ability to use the app in landscape mode.
Developer notes: Jetpack Compose was used to produce releases 3.0 and 4.0, fully replacing the use of fragments, a view model, and databinding in release 2.0.
