In fact, of the top 10 iOS apps for the quarter, 6 of them (Zoom, Facebook, Google Meet, Facebook Messenger, WhatsApp and Microsoft Teams) could be said to have this kind of use-case. Zoom's success was attributed to the effects of Covid-19 on interprofessional communication and collaboration. The video-conferencing software took this #1 spot away from TikTok, who held the record for most downloaded onto iPhones or iPads in 1Q2020.
This was found to be the case in the US market as well as for the global Apple-device sphere. A new Sensor Tower report for 2Q2020 concludes that Zoom took the title for most downloaded from iOS' App Store over those 3 months.
