I started a new project a few days ago that documents each app I use on my iPhone, by day. Every day, my first and last used app is the Alarm Clock. In the morning, to wake up; in the evening, to make sure it’s ready for the next day.
Because I do this, I can easily see which apps I’ve used each day, because the Alarm Clock will only be accessed at either end of the day. I don’t use any other function of the app during the day.
Just a fun little thing to see which apps get used each day (and which don’t).
I’ll post the results for the next few days with the same title as above, but with the day after it.
