A scholarly resource must be written by a scholar - an expert in the field, usually with a PhD or equivalent qualifications. Scholarly resources usually tell you about the author, so that you can assess whether s/he is a reliable expert on the information presented.
Walkmeter uses GPS to measure the distance of your walks and hikes outdoors. It functions much like a stopwatch. Open the app, tap Start, and use Lap when you want to log an interval. It maps your walk, and you can view time, speed, distance, and pace as you walk.
As a result, technology keeps finding new ways to give people a much-needed boost. One of the best recent examples is the augmented reality game Pokemon Go. The popular app rewards players for walking, and this has led people to walk as much as six miles per day in search of new and rare Pokemon.
