Why do people use WhatsApp? The answer is: mostly to make voice calls.

However, younger Brits (16-24) more or less equally used WhatsApp, Zoom and FaceTime for calls.

WhatsApp vs Other Messaging Services

21. WhatsApp Messenger tops the list of most popular messaging apps in Britain.


A 2020 survey of 18-64-year-old instant messaging users showed that 81% of them preferred WhatsApp Messenger over other platforms, using it regularly, followed closely by Facebook Messenger with 76%.

Snapchat was far behind with only 25%, whereas Telegram was among the least used chat services in the UK, with just 3%. When it comes to WeChat vs WhatsApp, in turn, the latter blew the former’s 2% usage rate out of the water.

22. Four out of ten adult internet users in the UK sent texts via WhatsApp daily in 2020.


While the daily use rate of WhatsApp for texting (40%) was similar to that of SMS (41%), the overwhelming majority of adult British internet users used texts for communicating throughout 2020. Specifically, 94% of them had sent texts, whereas 71% had used WhatsApp to message people at least once in the preceding year. However, only 57% used it on a weekly basis, in contrast to the 73% who sent SMS.

Facebook Messenger, in turn, was used by 44% of the UK’s online adults weekly for this type of communication, while the percentages of people using other services for texting were as follows:

Whatsapp 2021 Trends

24. In 2020, changes to WhatsApp messages were made to curtail the spread of fake news.

(Ofcom) (BBC)

Amid concerns that it was at the nexus of viral disinformation about Covid-19, in April 2020, the app imposed a limit on forwarding messages that had been copied and pasted upwards of five times, now allowing users to only share them with a single contact or WhatsApp group chat at a time. It resulted in a 70% reduction of such communications.

Further, in August that year, it introduced a search button that indicates that a message has exceeded the above number of forwards, allowing recipients to quickly check the veracity of the claims it’s making by searching the web about the topic.

25. The app dropped to 23rd place in terms of downloads in the UK in January 2021.

(The Guardian)

The WhatsApp growth data show that in early January, WhatsApp was the eighth most downloaded app in the UK, but dropped to 23rd by January 12. What happened!? Well, the company announced controversial updates to its privacy policy which drove prospective users away. This caused Signal, which on January 6 hadn’t even been in the top 1,000, to become Britain’s most downloaded app by January 9.

26. WhatsApp has some exciting new features in the works for 2021.


The popular app has a few novelties in the pipeline, including:

  • Support for multiple devices—at the moment, the service supports only two devices at a time: a phone and a computer. However, the new feature is expected to allow WhatsApp users to combine up to four different devices into a single account. An addition to this will be a new logout option facilitating the implementation of this multi-device update.
  • Instagram Reels integration—likely as part of the ongoing Facebook-owned apps synergy, WhatsApp will be displaying these short videos as well.
  • Read messages later—this means that the app won’t send you notifications if your chat is labeled “read later”.
  • Audio WhatsApp message speedup and disappearing images—this update would allow users to set the speed at which voice messages play and have image files auto-delete after some time.
  • Join missed group calls—you’ll be allowed to hop on group calls that you’ve been invited to even after they’ve started.

Wrapping It All Up

Looking back on these stats and facts, it’s pretty clear why this messaging service has become the behemoth that it is, particularly in the past year or so. Not being able to see our friends and family safely has made everyone far more reliant on digital ways of communicating.

However, will the changes WhatsApp is making keep it on top, or cost it significant chunks of its user base? Only time will tell, but there’s always the next “hot” app ready to take its place, after all.
