From the developer:
The Pitch Grid Test is a relative pitch test that evaluates your ability to discriminate pitch-distances. For the test, the notes are laid out in form of a grid: There are 4 rows of octaves starting from C2 to C5. The number of columns depends on the selected the grid sensitivity. E.g. 100 cents correspond to 12 columns (chromatic scale); 33 cents correspond to 36 columns. In this way pitch-distances beyond half-step precision get assessed.
