There are contradictory findings regarding the validity of cephalometric analysis apps compared with the manual and digital tracing programs ( 5). Smartphones as an electronic training resource are useful for clinical decision support and to prevent medication errors ( 4) however, there is a lack of a systematic approach to evaluate the accuracy and evidence resulting from the use of mobile apps. Specially designed medical and dental apps are one of the fastest growing categories of software, and as of today, more than 350 orthodontic apps exist, many of which can be accessed for free ( 3). In addition, superimposition of serial radiographs can be performed faster, and it also allows the user to obtain several analyses at a time ( 2). With the rapid advancement in technology, the manual method is gradually being replaced by digital cephalometric analysis software, which has numerous benefits, such as reduction in radiation doses, facilitated image acquisition, archiving and sharing, faster measurements, and easily determined treatment plans, as well as the elimination of chemical and associated environmental hazards. Since its introduction in 1931, cephalometric analysis has become a widely used diagnostic and clinical tool in orthodontics ( 1).
