So there’s BBM and iMessage for Blackberry and iPhone respectively which users to chat to each other but when it comes to a cross platform app for chatting, Whatsapp is your best bet!
Frankfurt, Germany-based screen designer Julian Kraske thought that the current interface design of smartphone app, WhatsApp, looks—in his words— “not really pretty”. His re-design gives it a fresh, sleek minimalist interface that’s seems visually simplistic and more intuitive when it comes to navigating.
So he didn’t like it and decided to give the app familiar to us all a new look. He’s not actually been commissioned for the project but i think the big shots at Whatsapp should seriously give this guy a call, What do you think?
