Since Google Meet is now a free service for all users, it comes as no surprise that it has surpassed 50 million downloads on the Play Store. COVID-19 increased demands for apps like these, so Google opted to give all of its users access to the app that used to only be free for GSuite users. It's not surprising that it went from five million downloads at the start of March, then 10 million users 20 days later, and now over 50 million. The platform has hosted three billion minutes of video meetings daily, through its iOS, Android, and web apps.
Google Meet is similar to Zoom in that it can have a single host with up to 100 participants. Skype and Facebook Messenger, on the other hand, are limited to 50 participants for its free users. Google secures Meet by requiring users to have Google accounts and lets users create and join meetings using codes. If you use Gmail, you probably see the option to start or join a meeting on the left sidebar of the web app, making it easier to use its service.
