I friggin' love the score tracking app Pindigo, especially in its newer version, but I just felt compelled to throw this out there.
The ultimate purpose: to track ones high scores. Perfect, great, awesome!!
Other than that there really isn't a way to standardize scores between players on particular tables at different locations because of the custom gameplay and score settings the owner sets for each table. Even if you know what your settings are for bonus multipliers, extra ball threshold and max spinner scores ECT, someone playing the same table in a public space can't tell what settings they have as easily, so how can we compare these scores?
Not being negative at all, I track all of my personal high scores through Pindigo, and encourage my friends to do so as well. I just wanted to encourage players not to feel underskilled when their hard fought high scores is still several billion under someone else's!
