Mobile chat apps like WhatsApp, Viber and Facebook are taking over mobile communication, replacing texting (SMS) and phone calls. WhatsApp is the biggest player in mobile communication in The Netherlands and most of Europe. WhatsApp's user base grows with roughly one million users a day world wide. But the resent acquisition of WhatsApp by Facebook (involving 16 billion dollars) creates a fear for privacy issues. People start doubting if they want to keep using WhatsApp. I suggest a cool alternative: Telegram!
