> That first week, the activity increase was significant—a boost of 955 steps, or an estimated 11 minutes of additional walking a day, according to study author Katherine Howe.

Isn't that already making users more active?

Pokemon GO is free. Not everyone can buy a Fitbit or other walking "interventions"...

Not a big Pokemon GO fan but I'd like to think it did make people more active even if it was just for a week.
