I am sure there is an article on this. For me, I try to limit screen time being WFH is with less social interaction, being glued to a screen and notifications. I downloaded Star Maps, fitness trackers and a flight tracker to know where planes are flying to (beyond the world of WFH). :)
Zoom, Google meet,- all the live broadcasting apps. Clubhouse jumped in at the best time as well. Not only that, but all training/ exercise apps on mobile phones. Overall all app marketplace rised up during pandemic period IMHO.
