Golf Pad now supports World Handicap System (available on Android now, coming soon to iPhone). It follows the guide published by USGA to implement the system. However it was brought to our attention that the formula for computing playing handicap (also called daily handicap) is different between WHS Australia and WHS USGA. Specifically, there is 0.93 multiplier applied to the computation in the Australian version.
We confirmed the difference with Golf Australia officials and will be updating Golf Pad to use the correct formula in Australia. An updated version is expected to be released in February 2020. In the meantime you can manually specify playing handicap: just uncheck the 'compute automatically' checkbox and input the value.
