Is there an iPhone app that can count things AND calculate a percentage?


iMore Question

I'm practicing my tennis serves. I'd like an app that can count the number of serves I've taken AND the number that are in, and calculate my accuracy percentage. I've found a TON of "tally counters" in the app store, but none that let you qualify the items you're counting. Obviously, it doesn't have to be specific to tennis. Any app that lets you conditionally count items would work.

Anybody got any ideas?

I'm not sure about percentages, but have you looked at an app called Tennis Keeper or Swing Tennis Score Tracker. Both work with iPhone and Apple Watch...

This counter is on sale today for free. I don't know of a counter app that would also do accuracy percentage. You may have to do that with a calculator.
