The purpose of this review is to assess the overall state of publicly available mHealth apps that claim to treat depression. This will be done by reviewing systematic reviews published after December of 2015, in follow-up to a systematic review published by Huguet et al. (2016). The apps discussed in this review were chosen as examples of noteworthy apps, and an application’s inclusion in this study is not an endorsement of the application, but rather a result of its review by a previous study. By reviewing previous systematic reviews, this study will highlight research gaps in the literature and identify methods by which the overall efficacy, usability, and sustained use of publicly available applications for the treatment of depression could be improved.
