Week one showed an average of 2 hours 54 minutes of screentime a day. Last week was 2 hours 9 minutes average. The big thing I wanted to stop was randomly scrolling Reddit and that went from 4.5 hours to just over 2 hours. The other big issue was scrolling Facebook Marketplace for cool stereo equipment, that I realistically can't afford right now, which went from just over two hours down to 1.5 hours.
Both weeks Tuesday seems to be my highest usage day, but given it's winter in northern British Columbia, that's also the day I do 3+ hours on my bike with the Zwift companion app running so I can control some of the online cycling experience. If anything the Zwift usage going up is a good thing as that means I'm riding more.
