RShellhouse:
Handicaps are already included for 14.1 (points heads up and multiplicator). Handicaps for 8-/9-/10-Ball might be something for the future.
Chadk:
No, sorry. Although it'd actually not be too hard as my app is a natively wrapped web app. But I don't own a Mac (for development), an iPhone or iPad (for testing) and the iTunes stores charges developers yearly (opposed to the Play Store with a one-time fee). There is an iOS app though of which I hear good things, even if it doesn't have the same feature set as mine. Not sure if it's German only, but I'd guess that it comes in English too.
Greetings
