Back in February, Facebook announced it was buying popular mobile messaging app, WhatsApp, for a whopping $19 billion. We later compared WhatsApp to Facebook’s in-house chat service, Facebook Messenger. We learned that, despite their core differences, they had a lot in common.

But how does WhatsApp compare to, say, another popular mobile messaging service like Kik?

WhatsApp is powered by your mobile number – it requires a working number for activation. Kik, on the other hand, doesn’t require a working number and it doesn’t require other people to have your number to work. One of its best features is anonymity. Yet neither chat service can be accessed from desktop; they’re both strictly mobile.

So which is the better chat app for mobile? Find out in the WhatsApp vs Kik comparison video below!
