This study aims to assess the safety and efficacy of HPDT-DA-013 digital therapeutic in adults ages 22 years and older with MDD or GAD. Participants access HPDT-DA-013 on their smart device or computer and complete treatment over a period of 8-10 weeks. During the treatment period, participants complete PHQ-9 and GAD-7 assessments, as well as safety and medication use questionnaires. After 8-10 weeks, participants will complete end-of-treatment assessments, and access to HPDT-DA-013 will be removed. Participants are then followed for a period of 12 months.
