It shows the thickness of armor and placement of internal modules, but why do we need to pay for the ability to have tier 8 vehicles and up as the target in encounter mode? I understand the reason for requiring payment to have premium vehicles, but why something that is normal? Also, there are many tanks that are not in the databases, or have incomplete databases. For example, most British and Japanese vehicles have no internal module placement data. This is also true with more recent tanks like the German light tanks, German separate medium tank line, and the US turreted tank destroyers. Also, a new feature that would calculate ramming damage is advertised as part of "the next major update," but when is the next major update? When the Jehovahs Witnesses fully disband? The point is that there is no definite time that would happen. I do recommend this app to give an edge by knowing the placement of modules, but dont expect much.
