I think for an app to speak "I Love You" in different languages for a while. And took some time to design an android web app using mainly html, JavaScript (I'm not sure if it is the html5 website...) in Feb.
It is a simple and fun (I think it is :P) app when you press the heart, it speaks out the "I Love You" in different languages.
