This weekend I came across this sports betting app that offers advice from professional tipsters called "Winning Sports Betting Advice" The app is free to download but you then purchase advice from professional handicappers and tipsters. It doesn't cover every sport but you can get betting advice on Basketball (CBK & NBA), Football (CFB & NFL), Baseball (MLB), Hockey (NHL), International Soccer, NASCAR, Tennis and Boxing. You pay between $5 and $10 dollars for advice on each league or sports. I'd happily pay this if the advice improved my winning average even slightly. Has anyone tried any of these iOS tipping apps and have they had much success with them?
