“The idea of waiting for something makes it more exciting” (Andy Warhol)
With Jack, rediscover the pleasure of anticipation. Send a message to your friends: the message will be delivered instantly but you decide how long the receiver must wait before he or she can read it. The waiting can be an hour, a day, weeks, or more … you decide!
In a world dominated by instant and ephemeral communications, Jack combines anticipation, patience and reward, for a truly unique experience.
