WhatsApp can save marriages.
Scientists have found that the messaging app gives rowing husbands and wives "another place to fight and make up" and that written correspondence provides spouses with the time to re-read and process the point made by their partner.
The researchers explain that the app allows couples to "hash it out digitally" in order to be more relaxed for later face-to-face conversation while emojis help partners express their feelings better.
Dr. Gali Einav, of Reichman University in Israel, said: "Correspondence over WhatsApp not only offers another venue to conduct the relationship, but it can also help save it.
"It actually provides an additional platform to maintain a relationship.
"We can re-read messages to better understand our spouses, hash out anger digitally, and become more relaxed face to face.
"We can also send nice emojis to help express our feelings."
