The Most Popular Chat Apps in the U.S. (2024 Update)

U.S. consumers use chat apps like Facebook Messenger and WhatsApp to keep in touch with friends, family, and their favorite brands and businesses. The demand for over-the-top chat apps grows every year. Which chat apps do consumers prefer today? And most importantly, which makes sense for your business? Today, we’ll compare the most popular chat apps in the U.S.

What Are Chat Apps?

Chat apps enable users to instant message on mobile devices and computers.

As mobile devices became ubiquitous, so did the availability of digital communication channels. Worldwide, 2.52 billion people use messaging apps on mobile devices, with usage expected to reach 3 billion by 2022.

Over-the-top (OTT) chat apps let users communicate without incurring data charges. As long as a user has access to a WiFi connection (rather than a mobile network carrier), chat communication is usually free.

OTT messaging apps are now the most popular smartphone apps, with almost 90% of global smartphone users utilizing at least one messaging app.

Communicating through mobile apps has all but replaced voice communication as the preferred means of distanced dialog between people. Businesses have also jumped on the bandwagon, using chat apps to engage with customers, improve service, and drive sales.

Top 5 Chat Apps in the U.S.

Are you interested in pursuing chat marketing for your business but unsure which app is best for you? Let’s review the top five chat apps in the U.S. today.

Use Cases:

  • People use Messenger as a separate utility, enabling them to converse in or out of Facebook, Instagram, Oculus, and Portal.

As the fourth most popular social networking app in the U.S., Twitter is a critical piece of any omnichannel marketing strategy.

  • People tweet publicly and use Direct Messages (DMs) to have private conversations within Twitter, individually or in groups.
