No_intervention: Usual Care

Usual care refers to the normal standard clinical practices immediately post-transplant to the 18 months following. Liver Transplant Recipients at sites have lab values taken weekly for the first 8-10 weeks post-transplant, shifting to every 2-4 weeks for the next 3-4 months, then monthly to every 3 months thereafter depending on clinical needs.~All sites follow a similar schedule of tapering clinic visits ranging from weekly in the first 4 weeks to every 2-4 weeks in months 4-6, every 3-6 months in months 7 12, and every 6 months in months 12-24. All sites assign each patient to a specific transplant coordinator, first paired with a transplant surgeon (first 3-6 months), and then a transplant hepatologist for the remainder of follow-up.~All patients and caregivers receive standard medication teaching prior to hospital discharge and then ad hoc. No routine text message reminders, caregiver reminders, or adherence alerts are used in usual care.

Experimental: TEST Intervention

Clinical activities for Usual Care will also be provided in the TEST arm. The TEST intervention is a technology-enabled strategy to routinely monitor regimen use, adherence, and persistence via a 'low touch', easy to use, online behavioral toolkit - Way to Health . It was developed by University of Pennsylvania researchers to automate behavioral intervention. The TEST approach includes monthly adherence assessments, with tailored adherence support. The following components will be included in the intervention:~* Monthly W2H Adherence Assessment \& Clinician Alerts~* Medication Reminders~* Laboratory and Appointment Notifications~* Supplemental Self-Management Support
