I heard about this app from the SGU podcast. It was billed as a science based sexual health tool. While I dont doubt that that is true as far as it goes... It doesnt go very far. The UI is sub par for a paid app and the content has less depth than the average magazine you could pick up for the same price in a grocery store checkout line. Good idea, poor delivery.
