⁎
Overall quality score was calculated by taking the mean of the scores from the four objective MARS sections: Engagement, Functionality, Aesthetics, and Information.
⁎⁎
The condition(s) the app targets: S – Stress, A – Anxiety, D – Depression.
a
App was only available on iOS at the time of evaluation.
b
App was recommended for COVID-19.
c
P-values were determined by conducting independent t-tests on the 20 apps that were available in both iOS and Android platforms. Statistical significance was defined as p < 0.05. Shapiro-wilk tests were conducted to confirm normality of the data.
