Not comprehensive, nor complete
The maps included in this app give only one or two static representations of the situation and fighting in that place. They are by no means interactive, nor are they clear depictions of unit movements. Similarly, the historical descriptions of the units involved, their tactics, intentions, and casualties are fairly rudimentary. (And could benefit from a copy edit for syntax & grammar, at least.) That being said, this app shows potential. I hope that it’s further developed.
