As a hack, i'm using the badminton score tracker right now, but it feels like misuse. E.g. i can't keep scores if i play both games, that way.
So i'm looking either for a generic score tracker or maybe the source code of the (official?) badminton tracker to maybe modify it to track Pétanque instead. You know, change some texts, the background image and what datafield is used.. etc.
I am registered Garmin developer, so i could probably contribute those things to achieve that.
Cheers!
