The study will be conducted in two phases with the following aims: (1) To passively assess the adherence to hepatitis C virus (HCV) treatment with ledipasvir/sofosbuvir using a wireless pill monitoring device in 33 patients (Phase 1, months 1-3). (2) To test the impact on adherence of using the active wireless pill monitoring device in conjunction with the HepCure web-based tool kit in 66 patients (Phase 2, months 4-9). Participants in phase 2 will be randomized 1:1 to one of two conditions: (a) Patients using the HepCure patient app linked to a provider using the HepCure Provider Dashboard; AdhereTech passively monitoring adherence. (b) Patients using the HepCure patient app linked to a provider using the HepCure Provider Dashboard; AdhereTech actively monitoring adherence (chimes and reminders enabled).
