Health Pack Games creates physics based games and has discovered the power of NAX. Michael Kloubkov, the owner of Health Pack Games, says that since they switched to NAX, advertising revenue has jumped from a few cents a day up to 800 dollars a day. 'It's really incredible,' says Michael, who also notes that it took them less than a day to switch to NAX. A key to their success has been the way Health Pack Games implement ads in their apps. 'It's all about placement and when you show the ads that really grabs users' attention,' says Michael. He is also very impressed with the in-house campaigns feature — which enables you to cross-promote your apps and websites.
