^aMARS: Mobile App Rating Scale.

^bPercentage of apps determined to be of high quality, determined by an overall score that reached above the minimum threshold score of above 3.0 out of 5.0.

^cItem 19 of the information subscale was excluded from the final calculation, as only 1 app supported the scientific literature published in this emerging field of inquiry, a similar methodology adopted by other researchers in this context [41].
