ChessBase (the company) has several chess analysis programs available: Fritz, Komodo Chess, Houdini Pro, Deep Junior and Deep Rybka. Do all of these programs use one and the same graphical user interface?
From the question Confused about ChessBase, the answer by @Apasserby sums the GUIs up nicely:
Deep Fritz 14, Houdini 4, Komodo 9 and Rybka 4 all use the same Graphic User Interface (GUI).
So yes, ChessBase uses the same GUI.
