 This rapid review aims to identify current methodologies in the literature to assess the quality of M-Health apps, understand what aspects of quality these methodologies address, determine what input has been made by authors from LUMIX, and examine the applicability of such methodologies in LUMIX. The results show that there is no all-encompassing appropriate means for evaluating the quality of M-Health apps, and limited consideration of current generic methodologies for application in LMIC settings has been identified.
