There’s a recent BBC documentary titled Secrets Of Silicon Valley, its not a bad watch at all. In part 2, the presenter installs an app to see how much time he spends on his phone through out the day. Very similar to what happened at the Quantified Self 2017 conference, but even I almost coked on my tea when the final figure of over 5 hours was announced for the day.
Looking at my own usage, over the last month I spent 19hrs 1minute over 384 pickups, looking at my mobile phone.
I admit this is so very low in comparison to others.
By the way I’m still looking for a decent way to do this without abundance of features, battery use and in a data ethical way.
