The social video platform, TikTok, which was already a favourite of teens is increasingly being used by adults looking for ways to pass the time during coronavirus lockdowns.
Users post short videos, no longer than 60 seconds but often as short as 15, to showcase their bite-size dance skills or share relatable experiences with a humorous twist.
The application, owned by Chinese tech company ByteDance, saw 65 million worldwide downloads in March, according to analytics site SensorTower.
In addition to the existing 800 million reported in January by DataReportal, the app is nearing a billion users - though TikTok itself does not publish such data.
