Work-from-home policies, social distancing and government lockdowns have increased the demand for video conferencing apps, for both business and personal use. According to a new report from App Annie, business conferencing apps have been experiencing record growth as a result, and just hit their biggest week ever in March, when they topped 62 million downloads during the week of March 14-21. Meanwhile, social networking video app Houseparty has also seen phenomenal growth in Europe during lockdowns and home quarantines.

The jump in business app downloads to 62 million across iOS and Google  Play earlier in March was up 45% from just the prior week. It was also the highest growth among any category across the app stores that week, the report said. And it was up 90% from the weekly average of business app downloads in 2019.

Much of the growth in the category is due to the increased adoption of apps like Google’s  Hangouts Meet, Microsoft  Teams and Zoom Cloud Meetings.

Zoom topped the charts worldwide in February and March, and continues to see high numbers of downloads in the U.S., U.K. and elsewhere in Europe.

Video calling and educational usage of Microsoft Teams productivity software had risen in recent weeks as employees work remotely and schools cancel in-person classes.
