WhatsApp is clearly a great messaging app — it just reached one billion daily users. But it's not always ideal to be holding huge conversations on your smartphone. You might not know that WhatsApp isn't just bound to your phone, though. You can use it on your computer, too. This lets you get a better look at photos, makes reading lengthy paragraphs a little more manageable, and allows you to scroll faster through group messages to get to what you're looking for.
