There is no single kiss to express different emotions, and in this application there are many, one for every occasion.
To send an "e card" with the App, browse in the iPhone book for who to send a kiss to, add a text message if you want, find the most appropriate theme for the occasion, and send the "love card" that’s closest to your emotions at the moment.
Kiss On The Fly is the best way to send "free greetings cards", "cards love", "greetings ecards", "valentine cards", "online birthday card". It is a nice "romantic idea" to rest in contact with your lovers.
